Modeling database have reverse engineer functionality ?

whether can use Jdeveloer10g Modeling database functionality to reverse the online table schema from Oracle database ?

Hi,
Yes there are two methods of reverse engineering tables.
The first is with your project selected in the Navigator go to File | New, go to the following node by expanding the tree in the New Gallery dialog 'Database Tier -> Offline Database Objects'. Now select the 'Offline Database Objects Imported from Database' and press OK, this will now invoke a wizard which will take you through the rest of the steps to import the tables.
The second method is create a connection in JDeveloper to your schema, with your project selected in the Navigator go to File | New, go to the following node by expanding the tree in the New Gallery dialog 'Database Tier -> Offline Database Objects'. Now select 'Database Diagram'. Enter a name for the diagram and press OK. A new blank diagram will now be created. You can now expand your schema in the Connections Navigator and multi-select the tables you want to reverse engineer, you can then just drag and drop these from the Navigator onto the diagram.
Thanks,

  • Reverse Engineer Models Using DB Links ?

    Hi,
    I have tables that reside in database A.
    I can access those tables from Database B using db link.
    Is it possible to reverse engineer the tables belonging to database A in a model. If yes How?
    Please reply.
    Urgent Requirement
    Regards,
    Prerna

    Hi Prerna Vij,
    Yes you will.
    - In topology, create a physical schema in your dataserver B. Put the name of the source schema on A and enter the dblink name you want to use.
    - Create a logical schema and map it to the physical schema through contexts
    - In Designer, create a new model using the logical schema you just created and build all the datastore manually
    - Use these datastore as source in your interfaces and choose LKM Oracle to Oracle (DBLINK)
    Hope it helps.

  • Designer 9i reverse engineer my database

    I have Designer 9i with repository on Oracle 9i server.
    I would like to reverse engineer my database from Oracle 8.17 server on a different computer - connection.
    How do I do that? Beging from scratch, what do I need, do I need to create new Application system? I probably would need one... Can I connect this specific applicatino system to a specific database?
    How to get the tables (and other objects)?
    What tool do I use? Database design transformer says - I don't have any entities in a.s.
    Entity relationship diagramer - that would be for designing probably, not for reverse engineering.
    Please help
    Thanks

    Rok
    You can do everything you have asked.
    The best way is to do the following:
    - Create an application system and name it appropriately.
    - Use the Design Editor tool
    - On the menu there is a option to "Design Capture" (this is reverse engineering).The menu path is Generate/Capture Design of/Server Model
    - This will ask you to enter the connect string for the db you want to capture
    - Then you will be presented with the objects in that db and you can choose which ones you want to capture
    The rest is simple from there.
    To help you I would suggest you go to the URL http://otn.oracle.com/products/designer/demos.htm on this site and at the bottom of the
    page is a demo section on Server Design and Generation. Take a look at the one titled: Capturing Database Designs in the Design Editor
    This will demo the step above. The other demos may also be useful as you want to change the data model or generate new schemas

  • Reverse Engineer in models doesnt give the right structure from Essbase

    Hi,
    I have created Hyperion essbase(source)/Oracle(target) Data sources,Physical Schemas,Logical Scemas and have linked them with the context.
    When I create a model - I hadTechnology as Essbaseand the right physical schema -
    In the reverse engineer tab, I have correctly selected RKM Hyperion Essbase,Types pf objects is table.I had set True to multipls columns and had given the data column as Accounts - and the data column members as "Sales","Cogs"
    Now when I reverse engineer, I assumed the columns should be populated as (dim1,dim2,Sales,Cogs) - But what i get is (dim1,dim2,Account,Sales,Cogs,Data) - The account member and data also comes along in the column. Any idea where i am missing out this?
    Eventually when i execute the interface, I am ending up in an error "com.hyperion.odi.essbase.ODIEssbaseException: com.hyperion.odi.essbase.ODIEssbaseException: Invalid column in the source"
    Please share your thoughts...
    Leo jose.

    Hi,
    Please ignore, it is just that when a model is reverse engineered, it is having the old in memory and the new changes made in the model is getting appended along with the old dimension information creating some confusion.just did it with a different application and is giving desired results.I asked and I answered :)

  • Can SQL Dev Data Modeler be used to reverse engineer Windchill PDMLink

    Does anyone know if SQL Developer Data Modeler be used to reverse engineer Windchill PDMLink Oracle database? I need to get the DDL and ERDs from Windchill PDMLink.
    Can SQL Developer Data Modeler be used to reverse engineer object oriented Oracle databases?

    SQL Developer Data Modeler be used to reverse engineer Windchill PDMLink Oracle databaseprobably you mean Windchill PDMLink tables in Oracle database - yes, it's possible to get the structure of tables.
    Can SQL Developer Data Modeler be used to reverse engineer object oriented Oracle databases?It's not clear for me - you can reverse engineer definition of object and collection types, definitions of tables and views including those that use object and collection types in their definition.
    You can try it.

  • Reverse engineer data model

    I was trying to reverse engineer database information into a data model diagram in visio 2000.
    I received the following error :
    Encountered a fatal error during reverse engineer of information from database
    My Database version is
    Oracle9i Enterprise Edition 9.2.0.5.0 64bit
    Is it true that Visio does not support Oracle 9i (as I was told) ? If so, is there any freeware on internet where I can do the same (reverse engineer)
    Thanks

    You can use most any ERD product to reverse engineer an existing system: oracle designer, ERWin ,ER/Studio, etc....
    But it is likely to be a very manual process.
    If the application does not make use of database defined FK, UK, and PK then you will likely be forced into reading source and/or running traces on application processes to follow the DML.

  • Reverse engineer Toplink mapping to a ERM diagram

    Hi,
    We have a Toplink mapping for our application, the problem is that in the database no foreign keys relationship are defined, thus the relations
    are only in our Toplink model and not in our database. Id like to create a ERM model with for instance the new "Oracle SQL Developer Data Modeler".
    Is there a way do reverse engineer a Toplink model to a ERM diagram?
    Regards Jonas.

    Hi Jonas,
    unfortunately there is no support for Toplink.

  • Reverse Engineer / Import Selected Objects

    Hello All,
         I am new to ODI tool and trying to understand, how to reverse engineer / import selected objects? I am unable to do this.
    For instance, I have 10 tables in database, I want to import/reverse engineer 3 of them, how do I this in one go? I am able to do this, one by one.
    Your Help is appreciated.
    Thanks,
    Andy.

    Hi
    Create a model.--> click on selective reverse engineering---> check New Datastore and object to reverse engineer. then you can select 3 tables out of 10 tables.
    what do you mean by import here ?
    Are you trying to  import 3 tables from ODI ?
    Thanks

  • How to use database look up table function in xsl mapping

    Can anybody tell me how to use database look up table function while mapping xsl between 2 nodes.
    I have an XML file coming in and depending on one of XML elements we need to decide which further path to take. But, using this XML element, we need to query database table, get metadata and accordingly take appropriate path. I have written lookup function which returns metadata value.
    Now, the issue is how do I pass the XML element valu as input to look up function? When I tried to drag it to the input node of lookup function, it throws an error like "Maximum number of parameters exceeded"
    Thanks,

    If the lookup table is always going to remain the same (e.g. a character generator or something similar) you can place the values in a 2D array constant on your diagram, with the input value as one column, the equivalent as the other. When you need to perform the lookup you use an index array to return all the values in the "input column", search it using "search 1D array" and use the resulting index number to index the other column's data. If the values may change, then it would probably be best to load an array control with your equivalent values from a file.

  • 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.

    Any comments on this issue?. Please let us know.

  • Reverse engineer using DBMS_METADATA

    Hi,
    Can I use DBMS_METADATA package to reverse engineer a scheduled job from the database. I tried running below statement but it only returns the first job no matter what I do:
    select JOB,WHAT,dbms_metadata.get_ddl('JOB',USER) FROM DBA_JOBS
    I even used a where clause to make sure that I am using a specific job but the output remains same I mean I get statement generated only for first job.
    Any thought?

  • Enquiry:  Any tool to reverse engineer an existing db schema in Oracle 8i

    Dear All,
    Do you know whether Oracle SQL Developer Data Modeler (3.1.1.703) supports Oracle 8i? If not, is there any tool that can be used to reverse engineer an existing database schema in Oracle 8i?
    Your early reply is appreciated.
    Thanks a lot.
    LAWRENCE CHOW

    That's a pity. The initial version of Data Modeler used to support import from Oracle 8i.
    You could try setting up an ODBC connection to your database and using the JDBC tab (rather than the Oracle tab) when entering the Connection details into Data Modeler.
    Alternatively, if you can get hold of an earlier version of Data Modeler (e.g. version 3.0 or earlier), you could try this (and if it works you could then upgrade your model to the current version).

  • Reverse engineer issues in ODI 11g

    Hello gurus,

    Please help ?

    Thank you so much for your reply....Yes thats exactly right it is not considering the deleted columns....when i try to remove the the data store it gives me an error saying

  • When i reverse engineer CSV file into datastore It is not diplaying coloums

    Hi All,
    When am trying to do reverse engineer the CSV file in the datastore it is not displaying all the Coloums at a time.
    Can anyone suggest me , how to do it
    Thanks & Regards:
    Vamsi

    Hi,
    Unfortunately there is no way of changing the delimiter from within DM. It's comma and that's it. I've logged a bug on that.
    Here is a workaround though. Open CSV file with text editor and use Replace functionality.For search mode you have to select Regular Expression, Type this:
    search string : (?![^(]+\)),
    replace string : ;
    This will replace all commas with semicolons, except those in brackets.
    I've tested it with Notepad++ (it's free). I think it can be used for all opened files at same time.
    Hope it helps
    When exporting, could you check that null pointer exception in log file and post stack trace here? Not entire file of course, just first 20-30 lines. Thanks
