What are the advantages of idoc compare to flat file. how data is secure

what are the advantages of idoc compare to flat file. how data is secure in idocs compare to flat file

Hi Ramana,
In simple words, Main advantage with idoc over flat file is security....
I will explain you some scenario here U got a flat file with all the data...Now u r having the flat file if you want u can modify the data in it, or somehow any one can modify the data in it  if they were able to access this file. That means u maintained the file in the presentation server
One level of higher security to the above level is maintaining the flat file in application server, at point also even though lot of people r not having the access to that file, super user who is  having  the access may modify the data or delete the data from it rite....
so in both of those levels u don't have 100% security...
So there come to the picture of idocs, Idocs simply data carriers, those r generated by a program but not manually...data will be divided into number of segments based upon ur program. So manually its not so easy to modify the data in these idocs. If any changes to be made in the data then u have to modify the data in the application and then u have to update the idoc or you have to generate the new idoc with that corresponding data. so in this case not even super user can manipulate the data directly in the idoc....
I think u got my point what I mean to say.....
If you find it useful mark the points

  • What are the advantages/disadvantages to "Save Media Cache files next to originals when possible?

    I just noticed that I have over 7,000 files and 46.7 GB in my Media Cache Files folder.  I know I can just delete all the files in this folder and Premiere will automatically rebuild the files when needed.  But, are there any advantages or disadvantages to saving the files next to the originals?  I assume that means that it will write these files wherever I'm storing my media files...

    I'd say storing your cache with your media would decrease your performance.  Having them on separate volumes/drives means that Premiere can read/write from them at the same time, instead of having to read/write one or the other, one at a time.
    Additionally, PPro is create cache files from your original media, and it's always best practice to read from one drive, while writing to another.
    TL;DR It's for Performance. ! ! ! !

  • What are the advantage of using Oracle Database when compare to SQL SERVER

    Hi,
    There are various differences between the two.
    1. SQL Server is only Windows, but Oracle runs on almost all Platforms.
    2. You can have multiple databases in SQL Server, but Oracle provides you only one database per instance.Given that the very term 'database' has s different meaning in the two products, this "difference" is absolutely meaningless.
    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 SAP ?

    what are the advantages of SAP when compared to other technologies?
    what are the basic advantages of SAP

    SAP's R/3, introduced in 1992, is the most used ERP system in the world.
    The R/3 software package is designed to allow businesses to effectively and efficiently operate a variety of business processes within a single integrated information system.
    The software is customizable using SAP's proprietary programming language, ABAP/4. R/3 is scalable and highly suited for many types and sizes of organizations and runs on six different platforms.
    SAPu2019s R/3 has been designed to be the best ERP system in the four areas of human resources, financial, supply chain management, and marketing. R/3 is also an international product, and meets the local fiscal, language, and tax requirements of most countries.
    SAPu2019s R/3 is very versatile, as it will operate on six different platforms, including the recently added Microsoft NT.
    The R/3 package includes several very attractive features like it has a three-tier client/server system. Providing three tiers offers scalability and easier adaptation to the specific needs of large companies and fast-growing companies.
    SAPu2019s R/3 is available in 14 different languages (German, English, Spanish, etc.) and also incorporates multiple currency features that provide essential information processing capabilities for multinational corporations.
    R/3u2019s modules are organized by the functional areas of financial, human resources, supply chain management, and marketing. While information is entered separately for each specific module, the modules are fully-integrated and provide real-time applications. This means that data entered into one module is immediately and automatically updated and reflected in all oft the functional areas.
    R/3 is composed of a single, virtual file structure with no subsystems.
    In addition, SAP has released u201CMySAP.comu201D which is software that provides for data interaction and processing connections with the Web.
    Financial and managerial accounting tools in SAP R/3 are contained in the financial accounting (FI) and the controlling (CO) modules. The General Ledger function in the FI module provides a comprehensive record of all information needed for external financial reporting. The accounting data is complete and accurate because the SAP system fully integrates all business transactions that were entered from all the operational areas of a company. In addition to the FI and CO modules, the SAP system includes the Investment Management (IM), Sales and Distribution (SD), Materials Management (MM), and Human Resources (HR) modules.
    Management accounting tools in SAP R/3 are cost center accounting, internal orders, product costing, and activity based costing, profitability analysis and profit center accounting.
    SAP R/3u2019s accounting features are modeled on German approaches to accounting, and thus they are well-organized and very efficient in processing accounting information and providing accounting statements and financial reports.
    As stated previously, R/3 offers multiple currency features and a three-tier system that is capable of meeting very high demands from the accounting system for either transaction processing or financial reporting.
    SAP was the first to implement integrated treasury capabilities. This attractive feature allows a corporate treasury department to function as an in-house bank by automating the control of cash flow, investment trades, and portfolio management.
    R/3 provides check writing capability in its Accounts Receivable component which very few other programs offer.
    Additionally, there is equal access to all data in the system. This means that personnel can access financial data directly from a computer screen rather than physically meet with the treasurer, controller, or some other similar person. In other words, R/3 offers real-time, immediately updated reporting.
    R/3 also provides for a "single data entry point" where the data entered from any location is instantly sent to all other appropriate modules in the ERP system.
    The accounts payable component of SAP R/3 contains four types of transaction blocks namely:
    ● The audit block● The receiving block● The vendor block● A manual block
    These blocks make it much less likely that improper payments will occur.
    SAP R/3 is organized with the concept that a business operates as a series of processes, which means that the company implementing R/3 may have to change and reorganize itself to properly fit with R/3 and use it effectively.

    Are you referring to compressed files in your statement?
    If yes, then let me give you a general idea about it -
    Compressed file occupy less memory space as compared to its uncompressed counterpart, and hence can be uploaded/downloaded faster than the uncompressed one.
    Moreover Compressed files are less vulnerable to Malwares and Trojans, provided it is Locked and encrypted as well, Uncompressed files are more vulnerable to Malwares and viruses in general.
    I would love to help you with your query however i need to know that in which context you are asking this question so that i can point you in the right direction. Moreover please let me know if you are facing any type of Technical issue in any Adobe Product or Online service.

  • 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!

    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

  • 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.

  • What are the advantage of using a passive monitoring technique ?

    What are the advantage of using a passive monitoring technique

    Hi Plawansai,
    I saw your question that is still unanswered.
    I believe an advantage of using a passive monitoring technique is that it won't interfer with live traffic, as it does not inject traffic into the network or modify the traffic that is already on the network.
    One drawback anyway, is that post-processing time can take a large amount of time with passive monitoring!
    A combination of the two monitoring methods seems to be the route to go.

    What are the advantages of varying write speeds and burn speeds?

    The slower the speed, the fewer burn errors (or, in other words, you'll burn fewer "coasters"). I've always tried to burn at a slower speed, i.e. 2x - 4x. I'd rather wait a few minutes more and I've never had any burn errors.

  • What are the advantages to using BlazeDS or Granite?

    We have decided to use Flex3 to upgrade our UI. We have heard
    good things about using Granite Data Services, but it requires jdk5
    or higher, and the same for BlazeDS.
    We are currently using Websphere 6.0 and are discussing our
    environment options: replace Websphere with JBoss 4.2 (Sun jdk6),
    upgrade to Websphere 6.1 (IBM jdk5), or keep the current Websphere
    6.0 (IBM jdk4). The concerns are upgrade cost, and time to develop
    and qa any changes to the environment.
    We would like to get some feedback on pros and cons of using
    Flex with these three environments. If we stay with jdk4, will we
    spend nn% more time writing code that could have been done out of
    the box with Granite? Are there improvements with memory, speed,
    etc. using Flex with a later version of the jdk? Will development
    time be shorter with a later version of the jdk? What are the
    advantages and disadvantages of using Flex with WebSphere versus
    JBoss?
    Thanks for your input!

    BBM and PIN messages are messages sent from one BlackBerry to another.  The message is composed by the sender and goes through RIM's secure server before being delivered to the recipient.  They are only available to BlackBerry users.
    The thing I like about them is how you can see if they've been received by the recipient.  Once the message reaches the recipient's phone, you'll notice a small 'D' at the start of your message.  This means it's been delivered.  When the recipient opens the message, that 'D' will switch to an 'R', for 'read'.  So now you know that it's actually been received by the recipient.
    One more great thing about these messages is that there is no limit to length.  As you're probably aware, most carriers limit text messages to 160 characters; not so with these messages, they can be much longer.
    BBM and PIN messages are the same type of message, but with PIN messages you're limited to just that one contact receiving it.  With BBM, you can have many contacts in on a chat or you can broadcast a message to many contacts at once.
    I hope that explains things for you.

  • I just purchased an extreme.  I have an express.  The sales guy recommended setting up a hot spot with the express and use the extreme as a base station.  What does he mean and how do I do this?  What are the advantages?

    I just purchased an extreme.  I have an express.  The sales guy recommended setting up a hot spot with the express and use the extreme as a base station.  What does he mean and how do I do this?  What are the advantages?  How do I set this up?????

    I think he means to set up the main extreme as the main router or "main base station", and then use the express to "extend" the network.
    You can look up the manual for your express here for more details:
    http://support.apple.com/manuals/
    Extend the range of your network by adding AirPort Express to your existing AirPortExtreme or AirPort Express wireless network (this is called a Wireless DistributionSystem, or WDS). "
    Extending the Range of an Existing AirPort Extreme or
    AirPort Express Network
    You can extend the range of an existing AirPort Extreme or AirPort Express wirelessnetwork by setting it up in a WDS. Wireless computers can connect to the network andshare the Internet connection, share files, and play network games. If you connect yourAirPort Express to your home stereo, computers on your wireless network can useAirTunes to play music on the stereo from iTunes. If you connect a USB printer to yourAirPort Express, all of the computers on the network can print to it.
    n Open the AirPort Setup Assistant on a Macintosh, or the AirPort Express Assistant on acomputer using Windows XP. Follow the onscreen instructions to extend the range ofyour AirPort Extreme or AirPort Express network.
    Note: Extending the range of a network using WDS may reduce overall networkperformance.

  • 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.
