SQL Developer data Modeler: Straighten Lines functionality

Hi,
Found out that the Straighten Lines functionality on relationships in the Logical Diagram does not work.
In the Relational Diagram is does work.
Is that a known bug?
Erik

Philip,
Found out in documentation that Straighten Lines functionality removes elbows, but in Relational diagram it also makes lines horizontal or vertical. That is, as mentioned, not how it works in the logical diagram.
Thought that that was also functionality, but now it proves not to be documented. So the releational behaviour is just an extra undocumented feature.
Still, this undocumented feature would proves very handy in the logical diagram.
Regards
Erik

MySQL functionality within Oracle SQL Developer Data Modeler

Hi all,
I've read a few forum posts here that lead me to believe that MySQL is not currently supported by the data modeler tool (Link #1 I got to by clicking on the Statement Of Direction link on the main page SQL Developer Data Modeler</title><meta name="Title" content="SQL Developer Data Modeler"&g… Link #2 I got to by doing a search on the word MySQL within the forum search):
Link 1:
SQL Developer Data Modeler Statement of Direction
Link 2:
Can datamodeler be used with MySQL?
SQL Developer (not the Data Modeler tool, but the database admin-type tool not for modeling) does support MySQL using the latest MySQL Connector J 5.1 driver but, strangely, it doesn't seem the Data Modeler supports it, though. Can anyone please confirm that MySQL is currently unsupported for the Data Modeler tool? Thanks in advance.

Hi,
it doesn't seem the Data Modeler supports it, though.
Data Modeler doesn't have specific support for MySQL - i.e you cannot generate DDL for MySQL. Though you can import form MySQL server using JDBC connection in standalone DM or using created MySQL connection if you are using DM inside SQL Developer.
You can import definitions for tables(columns, PK and UK constraints, indexes, foreign keys) and views.

SQL Developer Data Modeler Information Flow descriptions

Hello
I am new to SQL Developer Data Modeler. Is there a way to display on the Data Flow Diagram the descriptions on the Information Flow lines.
Regards
Ade

1) Is there a cross reference report so that I can check my information structures on the DFD diagram with the attributes defined at Logical Model diagram?you can use "File>Export>To Reporting Schema" functionality to export your design into Oracle database. Two tables there give usage of attributes/entities in processes - DMRS_PROCESS_ATTRIBUTES and DMRS_PROCESS_ENTITIES. look for "reports\Reporting Schema diagrams" directory under installation of Data Modeler - there are PDF files with diagrams of reporting schema tables.
2) How can I create a copy (synonym) for any of my information stores or external agents on the same DFD diagramgraphical synonyms are supported only for objects in Logical and Relational models.

SQL Developer Data Modeler scripting

Hi,
I'm looking for a new modeling software for my company. SQL Developer Data Modeler (SDDM) has many features that fit my requirements. But there are some things that I'm not sure can be done. I work mostly with Oracle databases but still need to support some legacy and non-sql databases. Please look at problems below and tell me if and how those things can be achieved. Any suggestions for alternative solutions are welcome too.
1) I need to be able process Database Model from command line without human intervention and starting any GUI applications, for example generate DDL script form the model. Does SDDM have any interface for that?
2) I want to be able to export Database Model into a file in a custom (legacy) format.
3) SDDM stores database description in xml files. Is xml format defined anywhere? Are xsd schema files availabe?
4) Is there a SDK available that would allow reading SDDM Database Model into a custom application for further processing?
5) Is there any Java library available that parses Oracle-11-compatible SQL and PL/SQL?
Thank you in advance
Tomasz Grygo

Hi Kevin,
thanks for sharing your thoughts. There will be much more advanced find/search facilities in next version of Data Modeler and scripts also will be covered.

Oracle SQL Developer Data Modeler Versus SQL Developer

Friends,
I'm trying to understand the differences between Oracle SQL Developer Data Modeler and the ability to use the Data Modeler in SQL Developer.
I've looked at both products home pages on OTN, http://www.oracle.com/technology/products/database/datamodeler/index.html & http://www.oracle.com/technology/products/database/sql_developer/index.html and would appreciate your comments on my findings so far
1) The Oracle SQL Developer Data Modeler is a stand-a-lone chargeable product whereas the use of the Data Modeler functionality of SQL Developer is free
2) The Data Modeler functionality within SQL Developer is basically a "viewer" I can create ERD's of my existing tables by dragging them into the modeler from the object navigator but that's about it. I can't save the diagram for later use or use it to change the structure of the table(s)
3) If I need to have "Oracle Designer" like ERD capabilities then I need to use Oracle SQL Developer Data Modeler (after purchase!)
4) Are there any other differences I have missed?
Thanks in advance

You can open any diagram created in the stand-alone product in the SQL Developer Data Modeler Viewer and navigate through all property dialogs and the full navigator, just like you can in the stand-alone product, but with no update capabilities. This allows developers to fully review the model and all properties, without making changes.

Does SQL Developer Data Modeler fit-in??

Hi Everyone,
Wish you happy new year 2011.
Does SQL Developer Data Modeler support conceptual, logical and physical in our modeling or only logical and physical?
We all use Erwin for modeling. Erwin works without database repository storing models in desktop folders and provide additional reporting. I find some place SQL Developer Data Modeler talked about repository need.
Does SQL Developer Data Modeler store the models in local/network folders instead of Database server?
What are the functions need database based repository to work with SQL Developer Data Modeler?
We are thinking of using SQL Developer Data Modeler for our conceptual, Logical, and data dictionary need. Will it help in our need?
Do we need to face any surprises on using SQL Developer Data Modeler for our need?
Thanks in sharing your experience and helping me out.
RI

1) Do we need to have Oracle database at back end to work with SQL Developer Data Modeler?No, Data Modeler use Oracle database only if you create reporting repository.
Data Modeler is free, you need database license only if you want to log service request
2) Will SQL Developer Data Modeler create any tables (as backend repository ) in Oracle database to store Model details? no
3) Do we need to create reporting schema in backend oracle database to generate reports of SQL Developer Data Modeler's items such as Entity/attributes etc?no, reports can be created out of current loaded design. However having reporting repository will give you additional benefits - history (reports can be generated for every snapshot of your designs there) and multi-user usage, you can create your own reports
4) Do we to use SQL Developer Data Modeler reverse engineer from DB2, SqlServer, Terra data etc?Data Modeler has full support for Oracle, DB2/390, DB2/UDB(LUW) and MS SQL Server. Reverse engineering from other databases (including Terra Data) is at generic JDBC level - you'll get some and some will be missing (no check constraints for example).
You can read release notes http://www.oracle.com/technetwork/developer-tools/datamodeler/ea2-releasenotes-185793.html

Oracle SQL Developer Data Modeler start up error

Hi All,
I just downloaded Oracle SQL Developer Data Modeler (2.0.0.57.0) [Released 1 July 2009] by selecting the option "Oracle SQL Developer Data Modeler for Windows (This zip file includes the JRE)"
After I installed the same and tried to run it by clicking datamodeler.exe, I get the following error message
"unable to create an instance of the Java virtual machine located at path:..\jdk\jre\bin\client\jvm.dll"
On the same machine I can successfuly run the Oracle SQL Develper with no errors. My machine is having Windows XP Professional SP3.
Any ideas? If there was a problem with Java, than the Oracle SQL Developer should also not run. But as stated it runs with out any error but the Oracle SQL Developer Data Modeler gives the above error.
Regards,
JAA149

1 - The above problem has nothing to do with the memmory. I tried on a 400 MB RAM, 900 MB RAM, 1.5 MB RAM & 2 MB RAM with the same arror.
"unable to create an instance of the Java virtual machine located at path:..\jdk\jre\bin\client\jvm.dll"
http://i30.tinypic.com/9vkwf6.jpg
2 - There are two "datamodeler.exe: files
One is at D:\datamodeler\datamodeler.exe
2nd is at D:\datamodeler\bin\datamodeler.exe
The same error occurs with both the files.
3 - The Oracle SQL Developer Data Modeler version is "Oracle SQL Developer Data Modeler (2.0.0.57.0) [Released 1 July 2009]" and the file I downloaded is "Oracle SQL Developer Data Modeler for Windows (This zip file includes the JRE) - (57M)"
If I look in "D:\datamodeler\jdk\jre\README.txt" I find
"Java(TM) Platform, Standard Edition Runtime Environment Version 6"
If I run "D:\datamodeler\jdk\jre\bin\javacpl.exe" I get
http://i30.tinypic.com/mt8ocn.jpg
If I run "D:\datamodeler\jdk\jre\bin\jureg.exe" I get
http://i28.tinypic.com/30boiyo.jpg
If i check at the control panle add/remove program
http://i30.tinypic.com/1428tba.jpg
If I go to "http://www.java.com/en/download/manual.jsp" and download "jre-6u16-windows-i586-s.exe" and run it.
If I go to "C:\Program Files\Java\jre6" I find the same files as in "D:\datamodeler\jdk\jre"
I am able to run Oracle SQL Developer with out any kind of error let alone the above one. But with Oracle SQL Developer Data Modeler I get the above mentioned error no matter what I try.
As the error states "unable to create an instance of the Java virtual machine located at path:..\jdk\jre\bin\client\jvm.dll". The file "jvm.dll" is located at two places. One at "D:\datamodeler\jdk\jre\bin\client\jvm.dll" and the second at "D:\datamodeler\jdk\jre\bin\server\jvm.dll"
A similiar problem occurs with JDeveloper with the fllowing solution
http://forums.oracle.com/forums/thread.jspa?threadID=506339&start=0&tstart=0
Which states the following
"hello!
in the problem with JDeveloper i have a solution. The jdk have a file jvm.dll in the path: jdk/jre/bin/client/jvm.dll this is the problem ... now in the path:jdk/jre/bin/client/ojvm has a file with the same name if you copy and paste this file to the another path, now its works fine your Jdeveloper.
Jdeveloper use two files to jvm.dll to work one in the folder /client and other in /server copy the same file to the two locations for precaution
for me work fine thanks..."
I tried to do the same (Copy from client folder to server folder)
D:\datamodeler\jdk\jre\bin\client\jvm.dll
COPIED THIS FILE TO
D:\datamodeler\jdk\jre\bin\server\jvm.dll
Nada. So I reversed it (copied from server folder to client folder)
D:\datamodeler\jdk\jre\bin\server\jvm.dll
COPIED THIS FILE TO
D:\datamodeler\jdk\jre\bin\client\jvm.dll
Does not work. So I tried another solution stated at the same forum entry
"Well,
i solved the problem by this way :
<SQLDEVELOPER>/jdev/bin/ide.conf
In this file, change this line :
AddVMOption -Xmx512M
by

Now, the executable is lauching correctly. No more errors with Java Virtual Machine.
But is it a good thing to solve it like that ?"
But the ide.conf file is only at "D:\sqldeveloper\ide\bin\ide.conf" which is for the SQL Developer and not the SQl Developer Data Modeler
Correct me if I am wrong but
JRE = Java Run Time Envoirment
JDK = Java Development Kit
And Oracle SQL Developer Data Modeler needs JRE and not JDK. In any case I download JDK
jdk-6u14-javafx-1_2-windows-i586.exe (121,306 KB) and installed it but no succcess.
I tried every thing except completely re-install my whole PC.
Any help will be much appreciated.
Cordially,

SQL Developer Data Modeler - 3000$???

The price is a joke, isn't it?
In which point is that tool better than the PL/SQL-Developer from Allround Automations for 180$?

You're not comparing the same things.
Oracle SQL Developer is FREE - compare that with All Round Automations in terms of functionality.
Oracle SQL Developer Data Modeler is a separate tool. It's a separate product and is comparable to tools like CA Erwin Data Modeler and Embarcadero's ER Studio - which are certainly not free.

SQL Developer Data Modeler - MAC Version 2.0.0 Build 570 - Issues

In no particular order
- The Help, About box displays a different version information set then the SQL Developer Data Modeler, About SQl Developer Data Modeler.
- Not able to move any portion of the connection between entities. Thus there is no current way to align the lines as wanted.
- There is no way to scroll all the way to the right side if you have more then approximately 5 entities horizontally.
- Open SQl Developer data Modeler, Click on File, Open, select an XML file and a dialog box is displayed.
- The checkbox needs to be moved to the right as it is partially cut off.
- the text next to the checkbox is cutoff and only displays "Don't show this dialog agai".
- Printing Diagrams does not print correctly unless you have the entities displayed such that you can "read" them. If you have diminished the display so that you are not able to see the table or
field names then the Print Diagrams does not display the entity or field names.
- File, Recent Designs, does not retain the last or any design having been opened and/or saved.
- VarChar2 is not a displayed data type for Oracle 10G.
- There does not appear to be a way to create a set of fields which you would like to have added quickly and easily to selected tables.
- DDL Editor displays the Macintosh HD. It should display my User Directory

Foreign key Mapping based on Data - in SQL Developer Data modeler

Team
Do SQL Developer Data modeler supports Foreign Key mapping based on the Data in the Schema rather defined at the DDL ? For e.g if we implement a Objects Relation ship mapping in Data base, we don't define Foreign keys at table creation.
Toad does this feature through "AUTOMATIC FOREIGN KEYS MAPPING IN TOAD DATA MODELER" more info at (http://toadworld.com/Blogs/tabid/67/EntryId/905/Automatic-Foreign-Keys-Mapping-in-Toad-Data-Modeler.aspx)
any one know how to implement through some scripts also helps me
Regards
Raj

If you have table PKs defined and the candidate columns match those PK columns, then you can use the Discover Foreign Keys utility. Right mouse over the relational model name (node) in the left browser. It is about half way down the menu. I did a blog post about it last week on kentgraziano.com.

Oracle SQL Developer Data Modeler 3.0 Bugs, Resolution and workarounds

The purpose of this thread is to list bugs discovered while using ORACLE SQL Developer Data Modeler 3.0
Mainly with SQL SERVER 2005 and ORACLE 10g models.

SQL Server Physical model doesn't save table identity column.
here are the steps to get this bug:
1. create a table in relational model with a column as an integer to be used as an identity.
2. create or open a physical model for SQL-SERVER 2005
3. open the table in the physical model
4. edit the integer column property dialog
5. tick the identity check box and close the property dialog
6. save the model and close it
7. open it again, you will find the identity check is removed! (probably not saved from the start)

Customising the Legend (Legend Box) - SQL DEVELOPER DATA MODELER

Hi,
Is there a way to customize the legend Box (obtained when you right click Show->Legend in the Relational or Logical model window) in the latest latest version of SQL Developer Data Modeler.
For example i would like to remove a particular attribute from the legend say Changed by or Author.
Thanks in advance.

Hi,
It is not possible.
There will be such option in the future.

SQL Developer Data Modeler - Relation to Foreign Key Generation

SQL Developer Data Modeler 2.0.0 Build 584.
I am having trouble with Relations to Foreign Keys when Forward Engineering a Relational Model from a Logical Model.
First of all, the Naming Standard is not applied to the Foreign Keys when I perform the Engineer to Relational Model.
So I right click on the Relational Model from the Browser and Apply Naming Standards to Keys and Constraints.
I uncheck everything but Foreign Keys.
Now, Foreign Keys are named according to my Naming Standards.
However, this process also performs renames on the Column Foreign Keys even though I specifically unchecked that option.
This appears to be a BUG in the software and I haven't found a way around it.
I tried using {column} instead of {ref column} in the Naming Standard Template for Column Foreign Key, but that simply resulted in renaming my columns to "{column}".
Please confirm and/or let me know of any work-around for this.
Thanks,
Dan

Hi Philip,
Thanks for the reply.
Is this recorded as a bug to be addressed in the future?
Should I submit this problem via Oracle Support?
The other work-around I came up with is to override every Relation name in the Logical Model with the name I want to use in the Relational Model.
When the Relational Model is Engineered, this becomes my Foreign Key name.
Of course, this is not how I want to do things, so I am hoping for a bug fix someday.
Regards,
Dan

SQL Developer Data Modeler: Logical model, unable to create arc

I have a logical model in SQL Developer Data Modeler. Entity A has two 'incoming' foreign key relations to entities B and C. Both releations have the same optionality and cardinality. I want to place both relations in an arc. I see the buttons in my toolbar menu, but they are not enabled. Even when I select both relations it is not.
Bringing the logical model to the relational model creates foreign keys. These foreign keys can be selected and when I do that the 'Create new arc' button in the relational model toolbar is enabled.
What am I missing in the logical model ...? The documentation doesn't give a clue.
Erik

Thanks Sue, that worked. It is different from the way the ERD in Designer worked. Is there any reasoning behind it. As far as I know you should only put into an arc two or more relationships pointing to the same entity with the same optionality and the same cardinality. Selecting the entity with the relationships can only help in identifying at which relationship end the arc should be created but that is obvious.
And asking the question is answering it: it will help in adding an arc to two or more entities originating and ending at the same entity (and same cardinality and optionality).
Is that the reasoning behind it?
Regards
Erik

How can I find out what is causing this error in SQL Developer Data Modeler

Friends,
I am trying to import entities into into SQL Developer Data Modeler from Oracle Designer 10.1.2.3.
In case of need I perform these steps to perform the import:
File --> Import --> Oracle Designer Model --> Select database connection --> Select work area --> select application system --> select one entity --> Click finish --> Import starts
During the import process I see an alert dialog box with the message:
There are errors in import - check Log file Clicking Ok dismisses the alert box and I see the following summary screen:

Thanks in advance for any help you may be able to provide.

No this helps a lot. It's not strange. Firstly, in a versioned repository you should see Private Workareas and Shared workareas, so your workarea may be in either of these. It won't be in the Global Shared Workarea, as this only for non-versioned repositories. (I like to open the RON by selecting the full Repository, that way I can see the private and shared worlareas and the configuration and containers all in the same tree.
Now your workarea is defined by a set of rules, so when you expand the workarea in the RON, and select the object, then that's the workarea and object you'll see in the import dialog in the Data Modeler. So if you check it out and check it back in, and can't see it in the RON, then the rule is not seeing this object. (Did you refresh the workarea in the RON?) If you can't see it in the RON, you can't see it in the Data Modeler. If you're working in a versioned repository, you need to work in the specific work area, i.e V27 and this is what you need to select in the Data Modeler.
It looks like you are selecting the wrong workarea in the Data Modeler.
