Oracle Data Modeling tool interoperability with QDesigner models.

Hello,
Would it be possible to get some information on how Oracle SQL Developer Data Modeler works with models from other data modeling tools such as QDesigner.
How can Quest QDesigner read the .cdm (conceptual data models) and the .pdm (physical data models) from QDesigner.
Regards,
Mary

SQL Developer Data Modeler does not work with QDesigner models.

Oracle Data Modeler - Impact Analysis option

Hi
I am using Oracle Data Modeler 3.1.0683 and reversed engineering my existing relational models to logical models. I have 3 relational models and reverse engineering it to 1 logical model.
In logical model under enity's propoerties -> impact analysis how do I add which relational table the logical entity depends on? For example in relational models i have table Class, Student, teacher in 3 separate relation model. Logical i created entity Person which depends on table Student from relational model 1, and teacher from relational model 2, I want to view(add) these tables under "Impact Analysis".
The help window says
<quote>
+"Impact Analysis+
+Enables you to view and specify information to be used by Oracle Warehouse Builder for impact analysis."+
</quote>
Though i couldnt figure out where to specify?
Thanks in advance.
Regards
Lahoria

So any suggestions how can I bring those table ( as i mentioned in original post) to show up in Impact AnalysisIf your entity is result of reverse engineering from relational model then you can find related table under mappings. The same if you engineer logical model to relational model.
If you start from column then you can see related attribute in logical model and usage in data flow diagrams and dimensional models

Oracle Data Modeler commit change seg physical table

Hello,
Sometimes when I record a data model, Oracle Data Modeler (SVN) given as outgoing a chage of segment of physical table , if you committees are to change, duplication of files in the physical model is produced. Later when you open the physical model gives errors that have duplicate files
How you can correct this error? Why the segment change occurs?
Thanks

Hello,
Versión 4.0.0.833.
No pattern is occasionally when shooting in the data model. How you can correct this error? Why the segment change occurs?

Hi everyone,
We would like to install Oracle Data Modeler in the Office. We have seen on the web site that we can download it for free. But if you open the price list it is announced for 3000 $ by machine.
We don't understand how is it working.
Maybe there is a larger version, or it is only free for personnal use...
Thanx for clear that up.

Migrating SAP BW into Oracle data model

We have a requirement where the exisiting data from SAP BW needs to be migrated into Oracle. Since I do not have any prior SAP BW experience, I wanted to ask the forum on what their thoughts are in converting the data model from SAP BW into Oracle. Would that be straight forward conversion for the fact and dimension tables into Oracle or are there certain things we need keep in mind while designing the data model in Oracle. For ex: indexes, keys, attributes etc if they are handled any differently between the two systems.

Hi
ERwin will not give you the functionality to derive the logical data model from SAP BW automatically, however Saphir from Silwood Technology (www.silwoodtechnology.com) does allow you to extract the detailed metadata from the SAP BW system ( as well as from other major standard or customised ERP applications - SAP itself, Oracle, Siebel, Peoplesoft and JD Edwards). Once this information is brought into its own repository, Saphir provides a range of powerful search and view capabilities to allow you to isolate the data you are interested in and then export that information to ERwin (or any other leading Modeling tool).
Saphir will provide you with details of the relationships and detailed definitions within SAP BW.
Hope this helps

Looking for a Good White Paper on Oracle Data Modeling

Hopefully this is the proper area in which to ask this questions - been looking around these boards for a while but can't find what I'm looking for. I'd like to get a good modeling overview for topics such as:
-- pros and cons of normalization, e.g., performance considerations when deciding to normalize some data (and incur the cost of joins) vs keeping it denormalized (and having simpler queries)
-- overall performance considerations
-- warehouse vs mart considerations, esp as they relate to front end tools that will sit on the data mart
A general data modeling white paper or PDF would be very helpful to get me started.
Thanks all!
Mike

You don't need a White Paper you need a college course or a book.
The book I have on my shelf, don't know if it is still in print, is CASE*METHOD Entity Relationship Modelling by Richard Barker
Addison-Wesley Publishing Company
ISBN 0-201-41696-4
Normalization isn't about pros and cons. For performance denormalize. For data integrity normalize. Most systems end up somewhere between 3N and 4N or with what is referred to as Boyce-Codd NF. Google is your friend here but buy the book or take the course. This is not a subject to be read lightly in a dozen or so pages.

Oracle Data Modeler query

Hi All,
I am using Oracle SQL Developer Data modeler tool. Find it a very good tool for database designing and its free. Here I can connect to Oracle database and get complete ER diagram, but I didn't see any place through which I can Reverse Engineer changes made to ER Diagram back to Schema.
Do anybody have any idea about this.
Thanks,
Danish

. Find it a very good tool for database designing and its free.Actually it's not free. The "free" version was an Early Adopter release and not intended for commercial use. The first production release is a very-far-from-free USD 3000 per seat. Worth it? Dunno, I haven't installed the production release yet.
The EA2 version of the tool does support forward engineering but it doesn't generate diffs between the existing schema and the new one, like Designer could.

Oracle Data Modeler Versión 4.1.0.866 -- issue compare model Vs BBDD ( index PK, UK)

Hello,
I have a Data Modeler Relational and physical, the data model has three. The three tables are in a BBDD. The primary key generate is usssing index , and when I generated the DDL only show alter table add constraint .... . until here everything OK.
if I compare the bbdd with Data Modeler , I get differences in indices that generated oracle when I create the primary key.
¿Is a bug or is there some way to fix it by configuration options?
Thanks

Hello,
So you have a Relational Model containing 3 Tables. I assume the Physical Model is for an Oracle database.
The primary key generate is usssing index , and when I generated the DDL only show alter table add constraint .... . until here everything OK.
I assume you are doing a DDL generation of your model (using the Generate DDL button above the diagram or using Export > DDL File from the File menu).
In the DDL Generation Options phase of the DDL generation, can you go to the Tables tab and check that the "Selected" check box for the relevant Tables is selected.
(This should normally be selected, but if you deselected it in a previous DDL generation, it will remember that setting.)
The "PK and UK Constraints" and "Indexes" tabs also allow you to control whether the constraints and Indexes are included in the generated DDL.
if I compare the bbdd with Data Modeler , I get differences in indices that generated oracle when I create the primary key.
¿Is a bug or is there some way to fix it by configuration options?
I assume here that you have input your generated DDL to your database and you are then doing a File > Import > Data Dictionary to compare your database definitions with your initial model.
It is likely that there will be some differences shown, due to defaults used by the database when the DDL is input (e.g storage properties for your indexes and tables).
I suggest you examine the differences (which will be highlighted in red on the Details, Storage Details or Physical Details tabs) for each object in the Compare Models dialog, and provided they are acceptable, select the Merge button to merge them into your model.
If you do not want some of the property differences to be merged, you should unset the "Selected" check box for that property before merging.
Note that it is possible to exclude specific properties from the comparison by selecting the Options tab in the Compare Models dialog, and then selecting the Properties Filter, Physical Properties Filter or Storage Properties Filter tab as appropriate.
I hope this helps.

Oracle Data Modeling

Hello, I download Oracle datamodeling-1.5.1-525 and I create a logical model of my future database. My database have about 127 entities, 974 attributes and 233 relations.
I want generate ddl sentences in oracle and generate my oracle scheme in my database (Oracle SE 10G R2). I tried to create a relational model throught to Designer -> Engineer to Relational Model (Ctrl-Mayus-F) but nothing happend. The program does not anything, no errors no models, nothing.
Can anyone help me, please?
Thanks you very much!!!
PD: Excuseme, but I'm Spanish and my English is horrible.

Hi Roberto,
do you still use build 525? You can try the latest version here [http://www.oracle.com/technology/products/database/datamodeler/index.html] . Please pay attention to "release notes" and remark there - "Note for designs created with earlier versions of Data Modeler – persistence has changed and it’s strongly recommended that you use the “Save As” functionality to create new version of designs".
New version will resolve possible inconsistencies and you can engineer to relational model.

Oracle Data modeler 3.1.0.700 freeze on MAC OSX 10.7.3

Hello,
I was used Data modeler 3.0.x on the same machine with no problems (use SVN+3 active users , atc...)
When I installed version 3.1.0.700 and model migration I have problem with stability of program
With any action, java freeze after a few minutes of using application (no response, 100% core CPU, memory allocation stable).
Freeze was initiated with actions such as import model, commit into repository, working with application (edit table metadata and other action).
Do you anybody have same problem ? Any solution ?
Applikaction use standard lion JDK (installation no con taints packaged JDK).
Thank you

Hello,
I don't have such behavior.
Did you try to run fresh installation of Data Modeler without migrating from previous version?

Oracle Data Modeler - No Table Relationship

I am having problems when I use the import data dictionary function. First I choose my schema and tables. then after the import is complete, the tables are there but, there is no relationship between the table's keys. I am not sure if I do not have it configured correctly or what it could be. All the examples I find online seem to work correctly. ANy ideas?
Edited by: user13161578 on Nov 12, 2010 8:31 AM

Have you tried with one of the sample schemas, like HR? Are you selecting tables with FK relationships between them?
What database version and Data Modeler version are you using?

Oracle Data Modeler Versión 4.0.0.825

Hello,
If open a data model with 4.0.0.825 created with a previous version, the PK attributes that are FK disappear (identifying relation)

Hi Philip,
I have created a new model to be sure of the test details,
I have created two tables in the logical model (T1 and T2) each table has two attirbutes (T1_a1,T1_a2 and T2_a1,T2_a2)
I have checked a1 attribute in both tables as a PrimaryUID,
I have created a relation 1:N source T2 and target T1, without surrogate keys and Identifing,
the T2_a1 has appear in T! table as expected, I engineered to relational model successfully,
I saved the model and my problems start right now,
First issue:
I opened again the model,
I try to engineer again without any changes and the dialog is showing me that the attribute T2_a1 in T1 table is not in the relational model, but it is in the relational model, anyway I engineered again and a new filed has been created,
I repeated this action ,
save the model, close the model, open the model, engineer again and the dialog is telling me that the attribute is missing in the relational model always, and is generating new fields in the relational models (5 until I decided to leave it)
in my real model this is happening for almost all the entities so is impossible to maintain the models, at the end I made the changes in the relational model and wait for the solution to engineer again,
Second Issue:
In the same model, I change the attribute T2_a1 in T1 table to include the attribute into the PrimaryUID
I save the model, in the xml of the entity are no changes, I don't know where is supposed to save this change,
I close the model and when I open again the attribute is not checked as PrimaryUID,
I checked the log and I have no new lines, the issue is not only checking or unchecking the PrimaryUID, is only an example,
I guess you have enough details,
to be honest I think is too strange for me that anyone has the same problem if was an issue so I think could be something related to my configuration but I don't know how to solve this problems,
thanks in advance

Oracle Data Modeler Installation guide

Dear All
I downloaded SQL Data Modeler 3.1 and I unzipped it. Still there is a setting is to be done in the Registry, which I forgot. Please help me to resolve this issue.
OS - Win XP SP2
Thanks
Nazik

Hi,
I assume you downloaded the version of Data Modeler that does not include a JRE?
The Java JRE should normally contain a copy of msvcr71.dll in its folder jre\bin.
If it's missing, you will probably find another copy in its folder jre\bin\new_plugin. You could try copying this to its jre\bin folder.
If you've still got a problem, you could download the version of Data Modeler that includes a JRE.
