Mapping reverse engineered tables to entities

I would like to know how to 1) create the backwards links between tables created in Designer by importing DDL to logical entities in the ERD, 2) identify where in the Designer repository the information that shows up in the Entity.Description, Attribute.Description, Attribute.Notes, visible on properties sheet within RON, is stored

I'm actually not wanting to reverse engineer tables to entities, which is what I believe would be accomplished by the recommendation given. I am trying to establish links (basically, populate sdd_tabent) for tables that I have created by running DDL into Designer to entities that are already in Designer. The reason we are using the DDL, rather than forward engineering the table from the entities, is that there are enough differences from the logical to physical, and the DDL is being reused from an existing system.
I did find out the answer to my 2nd question. All text can be viewed via the cdi_text view; selecting by TXT_TYPE and ELEMENT_TYPE_FOR will give the combinations I was looking for

  • Using Designer to perform reverse engineering for Adabas entities

    Hi Experts,
    Customer will migrate from Adabas to Oracle db. Is it possible to use designer to perform reverse engineering for entities of Adabas?
    Thanks for your help in advance.
    Queenie

    If there is an ODBC driver for Adabas, it MAY be possible, though I have never had an Adabas database to try it on. I know that Adabas isn't natively a relational database using SQL, which is what Designer's Design Capture utility expects, so it will work through ODBC or not at all.

  • Reverse engineering tables of different schema/user in oracle

    Is it possible to reverse engineer tables of another user or schema in ODI if I have read permission on that schema?
    for e.g. I created a data server connection to oracle db with username SE and I'm trying to reverse engineer tables of another user SW. SE has read permission on SW.
    Is this possible?
    Thank you for looking into this.

    It is possible if both users are in the same db and the other schema needs to be selected in the physical schema under topology.

  • After reverse engineering i have still the old deleted tables

    hi ,
    i dropped a table from database schema and go to ODI and run reverse engineering on my model which linked to the database schema through my logical schema, but the deleted table still exist in my model ??? i wish this dropped table automaticly deleted from my model..

    Hi,
    Deletion actual table will not reflect while reverse engineer.
    The Meta data has been taken into ODI. It has become an object of ODI.
    So you have to directly delete the data store to remove it from ODI.
    Hope it helps.

  • PD 16.5 SP03 PL03 slowness after reverse engineering

    Little background:
    We were using PD 16.5 SP03 PL01 and faced a lot of problems like error messages, exception error, slowness etc. I was recommended on this forum to apply patch PL03 to solve the problems. I have applied the patch PL03.
    Current Problems:
    (1) When we try to reverse engineer even one single table, first PD becomes very slow and if we don't save and continue to work, we will get 'PDShell not working' message and PD will just shut down.
    It doesn't matter how big the table is, it might have 30 columns or it might have 100 columns. It definitely becomes very slow once reverse engineering has been done.
    (2) If we are creating a new entity in LDM or a table in PDM and we are working on it for some time meaning adding 30 attributes. After a while, it will fail to save and you have to restart PD. If you are working on existing model, doing some modification work then it's fine. But the moment you start adding entities/tables, attributes/columns, it will fail to save eventually so we have to be careful all the time and to save frequently i.e. after adding 3-4 attributes/columns, because we know at some point it is going to fail saving and we will have to restart PD and that is very time consuming.
    I was hoping the latest patch PL03 would have solved these problems. We have a couple of other colleagues facing the same problems, so it's just not me.
    P.S.: We are using Teradata V14 and PD version is 16.5.3.3 and it's 32-bit.
    Is there any solution for this problem? Is it a common problem?
    Thanks,
    Perry.

    Thank you Benoit!
    Downloading now.
    Btw. concerning the PD crashes: it turned out to be a problem with hardware accelerated graphics.
    I ran PD from a Windows Virtual Machine using VMWare Fusion.
    VMWare Fusion supports hardware accelerated graphics in the VM - if and only if you the VMWare tools running inside the VM are properly corresponding to the VMWare Fusion version hosting the VM.
    For me this was not the case, since the VMWare tools did not properly auto-update.
    As a result, with 3D hardware acceleration activated in the VMWare Fusion Settings, every program that potentially makes use of hardware accelerated graphics (PD, Visio, Internet Explorer etc.) crashed.
    Not sure this helps anyone out there. But if you are facing PD crashes and also face crashes of other programs like Internet Explorer or Visio, malfunctioning hardware acceleration might be the cause of it.

  • JDeveloper capabilities for Reverse Engineering existing instances and data

    We are experiencing difficulty obtaining the indexes, synonyms, and triggers via reverse-engineering capture of existing 10g DB's. Does JDeveloper have the capabilities for Reverse Engineering all objects from existing DB's ?
    Will 10g JDeveloper handle reverse-engineering large 300 table schemas rich with large quantity of indexes, synonyms, & triggers?
    And last, how can a listing of the Data Dictionary be extracted /exported in CSV or excel format for review distribution? Via JDeveloper? We have a large distributed development, test, quality, and integration team which prefers to review various elements of schema updates and changes in excel.
    Thanx.

    Vicki-
    Thanks for the additional info. I was thinking you were most concerned with reverse-engineering existing schemas. I did not realize you were designing new schemas.
    When you mention ERDs, are you interested in logical ERDs (as compared to physical tables and foreign keys)? If you are interested in doing pure logical ERD modelling, then Designer is the way to go. It has been years since I worked with Designer, but it has ooodles of capabilities to forward and reverse engineer between databases, physical models, and logical models of schemas. It sounds like you might be using Designer today and are hitting some snags. Is this the case? If so, I suggest you see if Oracle Support or the Designer forum can help you get past the specific Designer issues. The forum for Oracle Designer is here: Designer
    Sue mention that JDeveloper does support database modelling. Here is a how-to for JDeveloper 11g that shows how it works:
    http://www.oracle.com/technology/obe/obe11jdev/11/db_dev/obe_%20databasedevmt.htm
    The how-to is pretty complete showing you forward and reverse engineering capabilities.
    A few more minor notes:
    1.The JDeveloper schema modelling features work on a physical (not logical) level. In other words, they work on tables not entities.
    2.The SQL Developer report features certainly work on "DATA". But, the "DATA" they work on can certainly be the data dictionary data. In other words, I can write a report in SQL Developer that queries all of the column names, column data types for a subset of tables. Then I can export that "DATA" into excel and use it for whatever your downstream needs are. The potential capabilities are practically unlimited.

  • Custom reverse engineering strategy

    Hello,
    I'am looking for a way to customize reverse engineering strategy (eg : hibernate + reversestrategy class).
    When generating entity, Eclipse default mode remove "_" in property name (naming standard). In my case, if database field was "test_Me", the field become "testMe".
    I can't rename field in database and some entity class have been already defined. So, is there a way to change default generated mapping strategy ?
    Thanks.

    Hello,
    I'am using Netbeans 6.9. It's an old projet and previous entity name match database table field name, I just want be in the "same way". Entity prop are generated with the tag @column. If I want that my property name match the database column name, I need to change it manually. Is the reason why I'am looking for equivalent Hibernate, a callback class that able to change the default behavior.
    Thanks for you help.

  • Unable to generate Logical Model Diagrams through Reverse Engineering

    Hi,
    I am currently using SQL Developer Data Modeler Version-3.0.04.
    I have generated Logical Model Diagrams from Relational Model Diagrams through Reverse Engineering (Done by pressing an" engineer to Logical Model button" on top panel of sql developer) .I saved the DMD file (source file) once i had done generating the logical diagrams.Now if i reopen the DMD and open the logical diagram again I found that most of the tables had lost their relationships.So i tried to regenerate the Logical Model Diagram again from the same Relational Diagram but it is not being generated unless i create a new Relational Diagram.Is there a way to generate multiple Logical Diagrams for the same Relational Diagram rather than creating a new one for each Logical Diagram to be created.
    Regards .
    Thanks in advance.

  • Reverse Engineering a Model

    I am using SQL Data Modeller to reverse engineer an Oracle database to produce a diagram for a data model that was made a while back now. I created the diagram successfully and was very pleased with the results and the process.
    However, since creating that initial diagram the data model has again changed and I would like the recent changes to be reflected in the relational model I created in SQL Data Modeller.
    Is there an easy way to update the model? I click File > Import > Data Dictionary (which is the original method I used) I followed the steps and was presented with a list of changes and asked to merge into the model. This seemed fine. However the new tables were not added to the diagram and when I dragged them on to the diagram from the list of tables I was not shown the relationships?
    How can I easily added these new tables to the model?
    Thanks, Mike

    Check to see if the FKs between the tables you are referring to were captured in the reverses engineering. If they were, they would appear on the diagram when you drag in the new tables. If they were not captured, make sure they actually exisit in the database.
    I beleive that in order to capture a FK in the reverse engineering you must select both tables to be captured. If you only selected the "new" table, I do not think the FKs will come in but rather only the table structure, PK, and indexes on that table.

    1. Bounce the Repository's DB Instance. Usually an indication
    of RME errors.
    2. Goto RAU and perform all of your maintenance
    a. Compute Statistics
    b. View Objects and Recompile all 'INVALID' objects
    c. Clear temporary tables.
    3. If you are reverse engineering with DBA privileges then you
    are going to retrieve alot of uneccessary objects. Be explicit
    in your retrieval.

    Hi
    Pl. use Return Purchase Order process, transaction code ME21N
    At the item details, look for the Return columns and tick it.
    MIGO_GR - Goods Receipt for Return Purchase Order
    Movement type will be 161 to deduct the stock and 162 for reversal.
    During Goods Receipt for Return Purchase Order, you do not have to change the movement type from 101 to 161 as the system will automatically assign the movement type to 161 upon saving the postings.
    However, before saving, check if there is a tick in the Return Column to ensure that it is a return Purchase Order.
    you can also do the outbound delivery ..
    Outbound delivery with VL01n and do shipment with VT01N by referencing to the Out bound delivery.
    I hope this helps,
