Comparison between OWB and PL/SQL development

Hello,
I am preparaing a presentation comapring development in OWB and development in PL/SQL.
Can anybody know the time saved by using OWB (ratio, percentage...) ?
Thanks in advance,

Hi,
1) OWB is simple to use.
2) we need not know the internal logic of PL/SQL to work on OWB.
3) All the cursors will be created automatically and nothing needs to be mentioned.
4) The GUI is very easy to operate and adding conditions are very simple.
5) The loading properties can be set easily and we know how the mapping will behave.
All said above are the advantages of OWB, but OWB is only a tool and a TOOL will always have its limitations.PL/SQL is a kind of programming language with which we can do anything and everything but in OWB we cannot make everything possible.
Regards
Bharath

Differences between TOAD for Oracle and Oracle SQL Developer?

Does someone know the advantages and disadvantages of using TOAD for Oracle and Oracle SQL Developer?
I work making reports with TOAD, but in a few days I will have to use the SQL Developer (because it´s free) unless I justify the necessity of using TOAD.
Could some that used both compare them?
Thanks,
Facundo.

Hello Facundo,
since we are rolling out new client PCs we switch from Toad to SQL Developer. Therefore I'm doing some training for the "normal" users and our developers.
Most users simply want to have access to the data in tables and views. For those there are 2 main issues:
- Filters get lost when exiting table while sorting is still applied. Since there is no way to apply filtering before entering the data tab this can become a great performance issue because sorting is applied to many many rows. For views it is sometimes impossible to open the data tab.
- Exporting date values to Excel needs some know how if you want to sort by this column in Excel, because the date is formatted as "Standard" meaning that the sorting is done as for a text column: 01.01.2009 is less than 02.01.2008. Here you have to use a workaround column with a formula (=1*<datecolumn>)
The greatest Pro is the easy sharing of connections and reports by XML files.
Our developers like the easy debugging in SQL Developer. Though they miss the feature that the source is compiled for debug automatically as in Toad. For this we have distributed a script that compiles any PL/SQL object for debugging.
There are only some Toads installed for DBAs and for users that need access to tables protected by policies that require authentification by OS user since this information is not passed under every circumstance.

Comparison between Forms6i and Forms9i

We have some client/server-based applications built in Forms6i and are considering to convert/rebuild them into Forms9i or JDeveloper as web-based applications. Has anyone done any comparison between Forms6i and Forms9i/JDeveloper? Or, can you point me to such documentation if existed?
Thanks.

For comparison between forms 6i and Oracle9i Forms check out the new features paper on:
http://otn.oracle.com/products/forms
Comparison to JDeveloper? How about the fact that you develop with Java language in JDeveloper and with PL/SQL in Forms.
I would suggest that first you try to run your application on the Web using forms 6i. This should be a very simple test to do. See how you like it and only then ask yourself if you really need to go to JDeveloper.

What are the Basic Differences between Oracle and MS-SQL server Database?

Hello,
anybody pls Guide me about the Differences between Oracle and MS-SQL server Database.and also IBM Databases also
Regards,
Balaram

SQL Server only works on Windows-based platforms, including Windows 9x, Windows NT, Windows 2000 and Windows CE.
In comparison with SQL Server , OracleDatabase supports all known platforms, including Windows-based platforms, AIX-Based Systems, Compaq Tru64 UNIX, HP 9000 Series HP-UX, Linux Intel, Sun Solaris and so on.
The SQL Server advantages:
SQL Server holds the top TPC-C performance and price/performance results.
SQL Server is generally accepted as easier to install, use and manage.
The Oracle Database advantages:
Oracle Database supports all known platforms, not only the Windows-based platforms.
PL/SQL is more powerful language than T-SQL.
More fine-tuning to the configuration can be done via start-up parameters.

Real-Time Data Sync-up between Oracle and MS SQL Server

Hi All,
I am looking for a solution to sync-up the data between Oracle and MS SQL Server in real time. Here, the structure of table is different (in the sense, the data in multiple table in SQL Server should be combined and put it in a single table in Oracle and vice versa).
Could anybody throw light on this plz?
Thanks in advance!

Comparison between Purisma and JCAPS?

I am researching several CDI (Customer Data Integration) solutions and I've narrowed this down to two solutions Purisma and JCAPS. I am mainly comparing the matching engines, record linkage efficiency and any machine learning capabilities.
Has anyone done a "head-to-head" comparison between JCAPS and Purisma?
Does anyone have any screenshots of the JCAPS record linkage tool for manual duplicate handling?

Why not write a test class? Shouldn't take long.

Comparison between 3750 and 3750-metro

hi folks,
is there any links which will provide me on the comparison between 3750 and 3750-metro? for exapmple, isis is not support on 3750 but it support on 3750-metro. The product information from cisco site is insufficient in term of the main differences :p

Hi Josh,
The Cisco Catalyst 3750 Metro Series is built for Metro Ethernet access in a customer location, enabling the delivery of more differentiated Metro Ethernet services. These switches feature bidirectional hierarchical QoS and Traffic Shaping, intelligent 802.1Q tunneling with class-of-service (CoS) mutation, VLAN translation, MPLS, EoMPLS, and Hierarchical Virtual Private LAN Service (H-VPLS) support, and redundant AC or DC power. They are ideal for service providers seeking to deliver profitable business services, such as Layer 2, Layer 3, and MPLS VPNs, in a variety of bandwidths and with different SLAs.
The metro switches have the PXF chips (which allow hierarchical QoS on the 2 "WAN" GigE ports, so several logical links can share a connection, and have soft bandwidth limits).
For more details on 3750-M switches have a look at this link

Comparison between PeopleSoft and Fusion

Hi ,
I need to prepare a document to show up the comparison between PeopleSoft and Fusion. For eg: Business Unit in PeopleSoft and what is the concept in Fusion that is similar to Business Unit. Can anyone help me with a document that will give me detailed comparison between PeopleSoft and Fusion.
Thanks,
Fathima Farsatha

I can't find any comparison on the internal database. Can you add more about your goals with the question? Are you stuck with a Business unit issue or functionality. Since Fusion was built form the ground up it is a completely different software product. If you have a very specific question then we might be able to collaborate with different groups and provide an answer or fix.

What is the difference/comparison between AppRf and WebCC ?

Q: What is the difference/comparison between AppRf and WebCC ?
A:
Comparison between AppRf and WebCC:
AppRF
WebCC
2300+ Apps under 21 app categories
Millions of URLs under 80+ categories
Need up to 7 packets to classify
Classified once HTTP GET is received
Classification
Classification + Reputation
Need AOS upgrade to get new Apps
Dynamic update of WebCC database
Static content based classification
Dynamic content based categorization / reputation

Or put another way:
Albums organise Photos
Folders organise Albums
A Photo cannot be in a Folder, only in an Album.

Session storage between Java and PL/SQL

Hi all,
We have made Java servlet using session storage. The data stored is valid until session is changed. Seems that session is changed during logon or even if web page (where the servlet is located) is refreshed!
PL/SQL doesn't lost the session storage data during logon. But is it possible to find Java session storage from PL/SQL session storage?
Java session storage doesn't use domain name or subdomain which are mandatory for PL/SQL session storage.
Portal version is 3.0.9.8.5
Thanks,
Jari

See my answer Session storage between Java and PL/SQL.

How to decide between OWB and ODI?

Having to decide whether to choose Oracle Data Integrator or Oracle Warehouse Builder like tool for creating a dataware house and loading data into it, what should I choose and why?
I'm an old pl/sql developer but new on datawarehousing (I've been dealing with it for few months) and I'd like to undestand what fits better for me. It seems to me that OWB and ODI look not very different to each other, don't they?
My Oracle vers. is 10gR2
Thanks!

Thanks!Oracle corporation's statement of direction says ODI is their strategic ETL tool and if you and investing into Oracle ETl for the 1st time then it is better to invest in ODI .
OWB will be supported and finally OWB and ODI will get merged into a single tool.
For a pl/sql guy like you , the code generated by OWB is easy to understand as OWB mainly generates pl/sql code ( apart from sql loader and sap abap code ) . But that should not deter you to use ODI as ODI generates mainly SQL code (plus sove native code depending upon the technology used and KM) .

MS Access 2010 and Oracle SQL Developer Version 4.0.3.16 Error

OS: Windows 7 Enterprise
System Type: 64-bit Operating System
I can not get MS Access 2010 to work/open with SQL Developer version 4.0.3.16.
ERROR when testing connection to MS Access 2010
"Status : Failure -Test failed: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified"
I added the 32-bit ODBC data source for the MS Access I am trying to use with SQL Developer version 4.0.3.16 with the "C:\Windows\SysWOW64\odbcad32.exe" application, but I still get the same error.
I appears that SQL Developer version 4.0.3.16.is looking at the 64-bit driver (ODBC Data Source) and I have no idea to direct SQL Developer version 4.0.3.16 to use the 32-bit driver (ODBC Data Source) when opening MS Access 2010.
Thank you in advance for your advice.

I downloaded the SQL Developer version 4.0.3.16 "sqldeveloper-4.0.3.16.84-x64.zip" that included the jre.
How do I check which Java JDK I am running (32-bit versuns 64-bit)?
In the command prompt I use "java -version" and I get this message "java is not recognized as an internal or external command"

Import data using Excel and Oracle SQL Developer - I need some help

Dear friends,
I'm using Oracle SQL Developer 1.5.1 and I need to import an Excel file into a database table. If I try to import this file in XLS format, fields and headers are correctly being shown and separated, but if I press "Next" button, it simply doesn't do anything - it stays stopped.
I did some search here in this forum and it seems to me that, when you try to import a file via XLS format, SQL Developer has bugs. Is this correct?
If I save the same file in CSV format and try to import the same file, it goes ahead, but SQL Developer is not separating fields and headers correctly. It combines all CSV fields into one - let's say Column0 and fields 1;TEST;01/01/2000 below the same Column0.
Saving the file in CSV format is not a problem, taking a very little time. But I don't know how to make SQL Developer import it correctly. Could somebody please help me? Thanks in advance.
Best regards,
Franklin

Hello K,
yes, you're right. I found the following topic after posting this question here.
Re: After update to 1.5.1, import from Excel fails
I downloaded version 1.5.0 and I'll use it whenever I import data from Excel.
Thanks,
Franklin

Comparison between cFP and cDAQ

Hi,
I'm looking for (as much details as possible) a comparisons between compact Fieldpoint and compact DAQ hardware. I'm trying to decide which hardware platforms to use.
TIA

Compact Fieldpoint is for installed, industrial type applications. It has a realtime operating system. The controller runs code to read inputs and operate outputs. The application can be distributed on an ethernet network. There are different modules available for different types of inputs and ouputs.
Compact DAQ also has numerous input and output modules. It is more intended for portable applications. It connects to your PC through a USB port. So the code would need to run on the PC
