Which are the advantages of OWB Mappings over PLSQL code?

Hi,
I was wondering which are the advantages of OWB (10gr2 or 11g) Mappings vs simple PLSQL code when the mappings are, for performance reasons, only generated in set based mode.
Regards
Maurice

I'd say it's the general benefits that an ETL tool is considered to have over hand crafted code e.g. maintainability and traceability. The latest versions of OWB also make it even easier to maintain TYPE2 dimensions etc.
Of course benefits go the other way as well in that if you want the optimum performing code then a skilled PL/SQL developer will deliver that.

What are the advantages of NI-XNET over NI-CAN

Assuming that I'm only interested in CAN, are there specific advantages to going with NI-XNET over NI-CAN?

Olivier: Thank you for the comments about the disclaimer in my recent post here. While re-reading the post, I realized that I mis-stated one substantial fact, and that was the network speed. I have worked with high speed CAN for so long I automatically stated 500 KBPS as the network speed I used to achieve the 95% bus loading. However, in this case I meant and should have said 250 KBPS. It is possible to run J1939 CAN at 500 KBPS (I haven't tried it) but the SAE has not as of this writing adopted 500 KBPS as a bus speed for J1939. As J1939 CAN frames are (to simply state it) merely CAN frames filled out to a full 8 byte data package (albeit with an extended 29 bit arbitration ID vs the standard 11 bit ID of high speed CAN) and having examined the information Olivier pointed out (almost 9 months ago) I have no doubt that the XNET cards can deliver the high performance required to achieve near 100 % bus loading at the higher network speeds.
Now for more disclaimers:
I have exchanged emails and spoken with Olivier and others at NI at length about their CAN technology and have encouraged them to push the limits so those of us out in the field can continue to stay ahead of the competition using our favorite tool, LabVIEW. I have received no compensation for my views on this matter. For those of you that want to put my experience into perspective, I have worked with LabVIEW for 16 years & CAN for 5 years. My compensation comes from being able to get the work I am given done on time and under budget (usually ahead of time) - and I couldn't do it without LabVIEW and the support provided by National Instruments application engineers and the members and contributors to these forums. Thanks!

What are the advantages of forms10g developer suite over forms 6i

Hi All,
Am new to this Oracle Forms-10g developer, so I would like to know what are the new features of 10g over 6i. What are the main differences between oracle versions like forms-6i, forms-9i and forms-10g developer suite.
I even wanted to know what exactly is this OC4J Instance Start.
Thanks in advance.

Chandra Sekhar.

is the most ignorant answer I've ever seen on this forum.That's quite a horrible distinction to possess here. Frank, it's clear you took my post as a personal insult for a product you've worked on in a major way. That was not my intent, and for that, I apologize. I hope you will take most of my other posts here so far (the overwhelming majority of which are to answer questions for others instead of seek help for myself) into consideration.
I stand corrected on overlooking the enhancements related to the interfaces with Java.
There are perhaps a number of viewpoints to Chandra's question. Our users, who are focused on using the applications to do their job-- well, having the forms environment moved from client-server to the web is almost irrelevant to them, and losing client-server was no advantage. I guess I looked at it too narrowly from a pure Forms programmer's point-of-view. One of the things you describe as a new feature-- the ability to see GIFs in the builder, well since I saw ICOs in the builder in 6i, I just don't see an advantage as much as a change/fix to make it work like before.
Since I never looked hard at 9i release (which I admitted), perhaps I am ignorant to some new features. I went to OTN and looked up the 9.0.2 documentation, and didn't see what these 20+ features might be. If you would point me to a specific document, I would sincerely appreciate it.

What are the advantages/disadvantages of using PS/CS5 in 64bit over 32bit please?

What are the advantages/disadvantages of using PS/CS5 in 64bit over 32bit please?

From a practical perspective, besides the 64 bit version being a bit faster at just about everything, limitations on document size are lifted in the 64 bit version. Essentially, how much can do is limited only by how much RAM you have installed in your system. You can do things like have larger documents, deeper history, etc. and have it all work quickly.
On the other hand, many 3rd party plug-ins, especially older ones, only provide 32 bit versions, which will only run in 32 bit Photoshop.
Both 32 and 64 bit versions are installed by default. It's important to note that most of the preferences are separate between the two, so you can have two slightly different setups that might help with specialty operations you might need. This gets pretty subtle, but for example I keep the 32 bit version configured with only 1 cache level, so all previews of high bit depth images are always composited in high bit depth. This aids me with some aspects of astroimage processing. It's slower, but more accurate. By contrast I have more cache levels configured for my 64 bit version, so that's faster for general photography work.

What are the advantages..

Hi friends,
 can you please tell me what are the advantages of using MVC? because i can use ABAP Objects without using MVC.
Thanks in advance,
Regards,
Kannan.

Hi Kanna,
 For Dynamically componentised you need to use controller.In the main page you partition for what you want to present dynamically and then call controller as a response to the user.What the action you have take in case of Page flow logic(Event Handler) need to be placed in controller.
Using the MVC design pattern has the following advantages:
· Structuring BSP applications is simplified, since the view is cleanly separated from the controller and the model. This not only facilitates changing BSP applications, but also considerably improves their maintenance.
· You have the option of generating program-driven layout. The HTML/XML output is therefore created by program code instead of a page with scripting.
· Navigation using the <bsp:goto> element and call using the <bsp:call> element. The advantage of using <bsp:goto> navigation over redirect is that there is no additional network traffic. Furthermore, you remain in the same work process, which can have advantages for creating objects and memory space. The call using <bsp:call> element is more variable than adding them using INCLUDEdirective, since it is triggered at runtime.
With the call option using <bsp:call>, you can also distribute the user interface into components.
· Optimized performance due to fewer redirects.
· Intuitive and east-to-use interface for application development.
Main advantage of MVC is that you can keep these(Model View ,Controller) separately.If you need to change in logic you do not have to worry about presentation(View).

Hi Leela,
Your question is very straight question.

And i'll give some theory answer for ur questions
i.e.,SAP Business Workflow can be used to define business processes that are not yet mapped in the R/3 System. These may be simple release or approval procedures, or more complex business processes such as creating a material master and the associated coordination of the departments involved. SAP Business Workflow is particularly suitable for situations in which work processes have to be run through repeatedly, or situations in which the business process requires the involvement of a large number of agents in a specific sequence.
You can also use SAP Business Workflow to respond to errors and exceptions in other, existing business processes. You can start a workflow when predefined events occur, for example an event can be triggered if particular errors are found during an automatic check.
SAP provides several workflows that map predefined business processes. These workflows do not require much implementation. For an overview of these SAP workflows, refer to Workflow Scenarios in Applications.
Integration
SAP Business Workflow uses the existing transactions and functions of the R/3 System and does not change the functions. You can combine the existing functions of the R/3 System to form new business processes with SAP Business Workflow. The workflow system takes over control of the business processes. If you are already using SAP Organizational Management, you can use the organizational structure created there to have the relevant agents carry out the individual activities. It is possible to have an activity carried out by a position. This ensures that the respective occupiers of the position can carry out the individual activities during execution of the workflow. This means that personnel changes in your organization are taken into account immediately in the execution of a workflow.
Features
SAP Business Workflow provides a number of tools for defining and analyzing workflows as well as for monitoring operation.
The Workflow Builder is for displaying and making changes to workflows. You can make small extensions directly to the original workflows supplied by SAP, such as carrying out your own agent assignments or changing deadline monitoring.
There are several Workflow Wizards to support you in the definition of workflows, with which you can create specific parts of a workflow. The Workflow Wizard Explorer gives you an overview of the existing Workflow Wizards.
In order to make the functions of the R/3 Systems available to a workflow, you use business objects, which you can define and analyze in the Business Object Builder. These business objects are made available to the workflow in reusable tasks. The Business Wizard Explorer gives you an overview of all existing tasks.
The end user receives information about the activities they are to carry out in their Business Workplace. This provides them with a central overview of all the activities that they are authorized to carry out. They can commence the activities from here.
Several tools are available to the workflow system administrator, with which they can control and analyze the current workflows. The workflow system administrator is notified of problems automatically by the system.

What are the advantages of using an internal table with workarea

Hi,
can anyone tell me
What are the advantages of using an internal table with workarea
over an internal table with header line?
thnks in adv
regards
nagi

HI,
Internal tables are a standard data type object which exists only during the runtime of the program. They are used to perform table calculations on subsets of database tables and for re-organising the contents of database tables according to users need.
http://help.sap.com/saphelp_nw04/helpdata/en/fc/eb35de358411d1829f0000e829fbfe/content.htm
Difference between Work Area and Header Line
While adding or retrieving records to / from internal table we have to keep the record temporarily.
The area where this record is kept is called as work area for the internal table. The area must have the same structure as that of internal table. An internal table consists of a body and an optional header line.
Header line is a implicit work area for the internal table. It depends on how the internal table is declared that the itab will have the header line or not.
e.g.
data: begin of itab occurs 10,
ab type c,
cd type i,
end of itab. " this table will have the header line.
data: wa_itab like itab. " explicit work area for itab
data: itab1 like itab occurs 10. " table is without header line.
The header line is a field string with the same structure as a row of the body, but it can only hold a single row.
It is a buffer used to hold each record before it is added or each record as it is retrieved from the internal table. It is the default work area for the internal table
1) The difference between
whih header line and with out heater line of internal table.
ex:-
a) Data : itab like mara occurs 0 with header line.
b) Data: itab like mara occurs 0.
-While adding or retrieving records to / from internal table we have to keep the record temporarily.
-The area where this record is kept is called as work area for the internal table.
-The area must have the same structure as that of internal table. An internal table consists of a body and an optional header line.
-Header line is a implicit work area for the internal table. It depends on how the internal table is declared that the itab will have the header line or not.
a) Data : itab like mara occurs 0 with header line.
table is with header line
b) Data: itab like mara occurs 0.
table is without header line
2)work area / field string and internal table
which one is prefarable for good performance any why ?
-The header line is a field string with the same structure as a row of the body, but it can only hold a single row , whereas internal table can have more than one record.
In short u can define a workarea of an internal table which means that area must have the same structure as that of internal table and can have one record only.
Example code:
data: begin of itab occurs 10,
ab type c,
cd type i,
end of itab. " this table will have the header line.
data: wa_itab like itab. " explicit work area for itab
data: itab1 like itab occurs 10. " table is without header line.

What are the advantages to adding a server to my home/home office system?

What are the advantages to adding a server to my home/home office system?

It's hard to give you specific answers unless we know your current setup. Any server, or specifically OS X server, may not be appropriate for your workflow.
A server is a centralized computer which can act as a file repository for other computers and devices to access. It can also centrally manage authentication for other resources (ie, have a single sign in for multiple services), can act as a web server, a calendar server, and other features. Of course, many of those things are available from other providers, but having your own server means that you have more control (and responsibility) over them.
This is a good place to start:

Converting RAW to DNG! What are the advantages / disadvantages?

I have Canon cameras and shoot RAW, but the question itself is surely also valid for Nikon, Sony or other brand-shooters.
When importing my pictures to Lightroom, I could convert them to DNG but didn't do this up to now, because I do not know what I loose. I suppose that I loose the ability to process my files with DPP, but I will not do that anyhow. I can appreciate the advantage of having the file in an open documented format, where even I could easily write a reader for it. So the answer should not be what I can easily find in the Adobe introduction into DNG. I have also the DNG specification in front of me, and I can read it, because I once wrote a program to read TIFF files. I understand that I could add the original RAW image stream, but I do not want using up the space wasted for this. I know, that all development parameters used for the specific RAW image can be written with the image file instead of having those stored in a database or a side-car-file.
But what I did not find until now a technical explanation about what happens during the convert. Who can enlighten me? Where do I find the missing technical explanations?
Thanks in advance!
Lucien.

That wasn't the question... .
Based on the title of the thread and your initial post, it seems like your question had a lot of
"What are the advantages / disadvantages?"
in it, and only a little
"What happens at a technical level when converting"
But if you want more detailed info about conversion, and you have the aptitude to understand, I recommend doing what Lr5user-pt recommended:
Download the DNG SDK and dig in - all your questions will be answered (and if not, you can also ask DNG-specific technical questions in the DNG forum).
As far as my "sources" regarding the technical summary I presented, they are many and varied, none of which are the DNG SDK. In other words, my knowledge is based more on experience over the years - I don't know all the details under the hood..
Some experiments to consider doing:
* exiftool (-X) a proprietary raw file, then convert to DNG and repeat.
* open a proprietary raw in a DNG-supporting software of your choice and inspect metadata, then open the converted DNG in the same software and re-evaluate. Compare to proprietary raw opened in manufacturer's software, and what you see via exiftool.
Tom Hogarty (Lightroom project manager) and others who know have said: "DNG converter discards no metadata", and I believe them, but haven't verified for myself. Yet once proprietary metadata is in the DNG, most (all?) software will no longer decode it. A prime example is focus points - presumably they're there, but once converted, focus point feature is no longer supported. The amount of work required to support converted focus point data is unknown (to me), but as far as I know, no software has ventured to do it. If you want focus points, don't convert.
If you want the truth, I think for most people it's "not wise" to convert to DNG. Why? because unless you already know why you are converting (and need to convert to satisfy your goals), or you already know why you must NOT convert (e.g. so you can open the files in mfr.software, and see focus points..) the pros and cons are likely to be a wash, and now you have twice the number of raw files, unless you discard your originals, which would be REALLY "not wise", in my opinion. If you find the notion of "openly documented format" sufficiently compelling, then, ya know, more power to ya (I don't judge..), but there is no guarantee that DNG will outlast NEF (or..), and if it does, there will be ample opportunity to convert before you're left in the cold, unless you're stuck in a cave for a few decades, or are kryogenically frozen.. True, if all companies die, you may be able to write your own DNG converter (/reader), given the DNG documentation, but FWIW, NEF is also thoroughly documented (document is in freely downloadable SDK), and reverse engineerable (that's what Adobe and Phil Harvey does), so you could also write your own NEF converter, so not really a very compelling argument, not this year anyway - ask me again in a few decades..
If filesize is a main draw, then be sure NOT to save the hi-rez previews in your DNGs, otherwise you've just lost most or all of the filesize advantage. Also, you can strip previews from some proprietary raws (e.g. NEFs), to reduce filesize.
Personally, if DNG supported sidecars, I would be more likely to convert, because file-management/backup is only an issue if you "forget" about xmp sidecars (and I do not forget), and I'd rather have my xmp in separate ready-to-read xml text files, rather than embedded in binary files, but hey, that's me..
PS - I always use/encourage-others-to-use DNG when distributing raws to others for use in Adobe software, so xmp is not separate and can not get lost.
PPS - proprietary raws and dngs are both just glorified tiff files - raw data, previews, and metadata..
Don't get me wrong: I am NOT anti-DNG, and in fact - just the opposite: I am PRO dng, it's just that I wouldn't (don't) convert my own raws to DNG at this point. If you find the reasons to convert now are sufficiently compelling, you have my complete support and cooperation, fwiw..
Cheers,
Rob

I would like to combine multiple profiles into a new computer. Which are the most important folder or files to migrate?

The user profile in my old computer somehow became corrupted and I can no longer access it to log on. Unfortunately I was not aware of the Firefox sync feature at the time. I used a new profile and had to start from scratch to save new bookmarks and extensions/plugins. I did set up Firefox sync for this new profile. Now I have a brand new computer and desire to migrate the bookmarks to this new computer, including the original bookmarks in the old computer, as well as the bookmarks in the second profile. While I have located the profiles folder for each profile in my old computer (as well as extensions and plugin folders), the content of this folder is daunting. I would like to know which are the minimal folders I should select to migrate and would it be safe to simply copy and paste over the entire folder? Please note that I have also added new bookmarks into my new computer which I would not like erased. I hope these details are not convoluted.

Firefox has two methods of bringing in bookmarks from another Firefox profile:
* Restore a backup (JSON files in the bookmarkbackups folder): this completely replaces what you have, so is not the first step
* Import from an HTML file: this is additive and will create an Imported Bookmarks folder or add them under Unsorted Bookmarks
Restore is best if you tag your bookmarks because the JSON format preserves tags. If tags are not important, then it's easier.
What I suggest is:
(1) Export your current bookmarks to the HTML format; you can reimport these later. See: [[Export Firefox bookmarks to an HTML file to back up or transfer bookmarks]]. Open the file in Firefox (it's a web page) to make sure it looks complete before proceed.
Next, get the bookmarkbackups folders from each of your old profiles that you want to restore, and look for the most-complete-looking JSON files (they will have the most recent dates and largest number of bookmarks indicated in the file name). Proceed from the smallest set to the largest, or oldest to newest; basically, restore the most important one last.
(2) Restore a backup, then export to HTML. This article has the steps for a restore: [[Restore bookmarks from backup or move them to another computer]]. Then export to HTML and check for completeness.
(3) Repeat #2 until you get to the last/most important restore. You don't need to export that one.
(4) Import the HTML files you've made throughout the process.
(5) In the Library dialog, reorganize. Firefox doesn't have a deduplicator, but you might find one or more extensions to do the job on the Add-ons site if you find a lot of overlap.
Make sense?

What are the advantages of compressor and it it even necessary

what are the advantages of compressor and it it even necessary?

Necessary for some and not for others – probably a large majority – who can by with the presets avalaible in FCX.
The users who need Compressor are those who want to control the parameters of the encodes to get the best possible trade-off between file size and quality. Or those who want to do things like standards conversions, complex frame speed changes, better re-scaling capabilities, de-interlacing, re-interlacing, output formats beyond which are available in FCX, chapter markers for DVD and Blu-Ray authoring, batch conversions for multiple purposes through droplets, access to clusters for faster rendering.

Mobile hotspots---what are the advantages? better reception?

What are the advantages of getting a mobile hotspot---such as the Verizon Jetpack 4G LTE Mobile Hotspot MiFi 4620L---over simply using the hotspot feature of a tablet (such as the Samsung Galaxy 7.7" or a Motorola Xyboard 8.2") or smartphone (such as the Samsung Stratosphere)?
More specifically, is the reception better? For example, in an area of marginal data signal strength, would the mobile hotspot be more likely (as a sort of specialized device) to get a usable signal than would a mobile-hotspot-enabled tablet or smartphone?

Mobile Hotspot devices like the MiFi products are likely to be more configurable than the hotspot features you are provided with by your smart phone/tablet.
Probabally the biggest difference is that a MiFi can support more devices than your smart device. Another example would be purchasing a larger battery for a MiFi. Running a hotspot feature on your phone will drain your phone battery quicker. Haveing a MiFi may extend your battery life and connection sessions simply because the connected devices and mifi do not rely on each other for power. As AZ mentioned, performance will boil down to the hardware/radios that have been installed. More powerful equiptment will always perform better.
In reality they both do the same thing, provide you and others a connection to the internet that you can bring where ever you go.

FM7.1 to FM10 : What are the advantages?

Hello,
I have to use FrameMaker on Solaris, in a networked environment.
Currently I am using 7.1 and want to move to 10.
7.1 already has serious issues with importing pdf files.(http://forums.adobe.com/thread/891661?tstart=30)
You see I need to give some good reasons to my boss so as to convince him!
So 1st I want to know if there is a stable 10 ver. that works on Solaris.
2nd-ly it would be excellent if someone can say very briefly, what are the advantages/problems in ver 10 over 7.1 for Solaris environment.
Particularly looking out answers from the user "Error7103 "!
Thanks in advance,
DP

FrameMaker 8 supports Unicode too and is faster and more stable than FrameMaker 10.
Another question that has to be considered is:
SoLarry?
Do you want to make any investments in the former Sun platforms now owned by Leisure Suit Larry Ellison?
If you are running Frame native on Solaris, you are running on SPARC workstations. Sun discontinued those over a year prior to the Oracle Assimilation. Since then, even the Solaris x86 workstations are gone. Oracle is out of the desktop biz, except for thin clients. If a seriously nasty security exploit appears for SparcStations, ORCL may not patch it promptly. As your hardware ages and fails, you may find yourself getting parts from eBay.
I suspect that the bottom line for this inquiry is that it's not likely to be a an FM7 to FM8 upgrade on Solaris, but a total platform migration to Windows. The label on that can reads: Worms: species, quantity and condition unknown.

3. SQL Server provides T-SQL for writing programs, whereas Oracle provides PL/SQLWhich means what? Both products have a procedural programming language. They named them differently, and the languages are not interchangeable. Means nothing in comparing the features/strengths/weaknesses/suitability to purpose.
4. Backup types in both are the same. (Except Oracle provides an additional backup called Logical Backup.)You make that sound like "Logical Backup" is something more than it is. It is nothing more than an export of the data and metadata. Many experts don't even consider it a backup. I'm sure SQL Server provides the same functionality though they probably call it by some other name.
5. Both provide High Availability.Well, I guess they both have a suite of features they refer to as "High Availability". But what does that really mean? The devil is in the details. Remember, the two products don't even agree on what constitutes a "database".
6. Both come in various distributions.???

If you are going for an Implementation, you can try SQL Server Express Edition and Oracle XE which are free to use.
Then you can choose whichever is comfortable for your needs.

What are the advantages of using LabVIEW projects in TestStand, as apposed to just a path to a vi

What are the advantages of using LabVIEW projects in TestStand, as apposed to just a path to a vi ?
I am modifying an existing workspace for a new product, and it seems like more work to add the vi's into a LabVIEW project
does it gain anything in the long run

Hi Rusty,
I wanted to quickly clarify on the integration between TestStand and LabVIEW Projects.
As Jeff mentioned, some of the big benefits of using LabVIEW Projects is to organize code and to namespace them.
For instance if you had a project called "Power Supply" that housed all your power supply code and had a VI in that called "Initialize", and another project called "Temperature Chamber" that also had a VI called "Initialize", both these VIs are namespaced by the project, so there is no longer confusion about which "Initialize" VI is being used.
Now from a TestStand point of view, in prior version of TestStand, we lost some of this benefit because TestStand did not know about TestStand projects and called VIs simply as un-namespaced VIs. However, in TestStand 2010 (released last year, free eval available at ni.com/teststand), we added the ability to (optionally) call VIs within the context of their projects. This means that:
VIs are now namespaced by their project, even when called from TestStand
VIs can use project specific constructs like NI-DAQmx tasks and conditional compilation settings
Note: When creating deployments, the VIs maintain their projects and namespacing, so this benefit holds true for deployments as well.
Additionally, someone had mentioned looking into using lvlibs to namespace your VIs for deployment. Two comments:
With TestStand 2010, this is no longer neccessary since the project itself namespaces the VIs
You might also want to look into LabVIEW Packed Project Libraries, which combined several VIs into a single file. Think of it as a DLL specific to LabVIEW that is as easy to call as normal LabVIEW VIs. TestStand 2010 can call VIs that are exposed by PPLs. In addition, the deployment utility can automatically pack your VIs into PPLs for deployment.
Hope this is helpful!
