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 engineering data model

    Can rational rose reverse enginner data model from database (i.e. read the schema in db and then generate the ER diagram)?

    Yes you can reverse engineer datamodel from database. Following steps will help you in doing it. I did it using Rational Rose 2001(a) Enterprise suite edition.
    1. Go to Tools->DataModeler->Reverse Engineer option
    2. Reverse engineering wizard dialog box will be shown.
    3. Select Reverse engineer from Database
    4. Select your target database. Enter username/password and service name
    for your database.
    5. Test connection option is also provided. You can test the connection using this option.
    6. Available schemas in the selected database will be displayed.
    7. Select the schema of your choice and it will generate the datamodel.
    Hope it helped you.

  • 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 :)

  • Reverse engineer issues in ODI 11g

    Hello gurus,
    We are testing ODI upgrade and we have an issue while reversing a data model.Its an existing sql server table and in ODI when we click on the reverse engineer ODI datastore doesnt sync with sql server DB table.
    Please help ?
    Thanks,
    Mastan.

    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
    "object column : workflow_activity_identifier is referenced by: Txt CrossRef : 12142111, Txt CrossRef : 20617111
    Cannot remove"
    i think i have to edit my interfaces which is using the data store ? is there any way i can know how many interfaces are using this data store?
    Thanks for your help.

  • 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 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.

  • 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,

  • Not able to see executions in operator - Reverse engineer problem

    Hi All,
    I´m starting a new project, this is the situation. I've created the agent (physical and logical), it's running as a service (OPMN instance). When I execute the test, "Agent test Successfull". So I guess that is not the problem.
    I'm creating a new model, I've already created the Data server (SQL server), connection test is Ok, I've also created the physical and Logical Schema. The problem is after creating a new model, when I select reverse engineer option, everything looks like that data is being correctly retrieve, however data do not appear in the model. When I go to the operator to check the log, nothing is there. Any idea?
    Thanks in advance,
    Gonzalo.-

    >
    Do you mean to to say that uou are not finding any infor about the reverse engineering process in Operator ?
    If yes then please note Standard reverse engineering does not list down the operation performed in Operator.
    If you are using some RKM then only it will display the steps performed in Operator

  • SQL Developer Data Modeler suggestions

    Not sure where to post this (unable to connect to the blog from work due to network restrictions), hope this is the correct forum.
    I am testing out the Data Modeler product. I've got a large database that I want to reverse engineer, then work with the resulting model. I used the import feature which successfully imported all 1849 tables from my schema. However, this created a diagram which wasn't really useful. A couple of things I believe would be useful.
    1. Add better connectivity between the browser that shows the table listing and the diagram. When I click on a table, I'd like the corresponding element in the diagram to be highlighted (and vice-versa). Also, an option to have the diagram show that table would be useful (maybe a ctrl-click or shift-click).
    2. Subviews - I don't see an easy way to add to a subview once it is created. So, add an option to the browser and diagram right-click menu to "Add to SubDiagram". Currently the diagram allows you to create a subdiagram, I didn't see an add option.
    3. More keyboard shortcuts. Specifically, CTRL-Z to undo, CTRL-Y to repeat.
    4. Defined column types. You've got naming rules, but I'd like to be able to define columns as a predefined type, like "Dollar Amount", which would make my column become a number(9.2) or something like that.
    That's it for now - may be more to come.
    Don

    Hi,
    Thanks for the feedback. Most of these are in the product:
    +1. Add better connectivity between the browser that shows the table listing and the diagram. When I click on a table, I'd like the corresponding element in the diagram to be highlighted (and vice-versa). Also, an option to have the diagram show that table would be useful (maybe a ctrl-click or shift-click).+
    Go to Tools > General Options: Select Diagram and check the synchronize with tree option.
    +2. Subviews - I don't see an easy way to add to a subview once it is created. So, add an option to the browser and diagram right-click menu to "Add to SubDiagram". Currently the diagram allows you to create a subdiagram, I didn't see an add option.+
    There are threads in the forum about subviews and you can look at the demos available online on the [Data Modeler|http://www.oracle.com/technology/products/database/datamodeler/index.html] page - we'll be adding more, but the import from Data Dictionary demo talks about subviews.
    In short, select a few objects, right-click and create subview from selected, or right-click on the subview node in the browser and select new subview, and then drag the tables you want onto the new diagram.
    +3. More keyboard shortcuts. Specifically, CTRL-Z to undo, CTRL-Y to repeat.+
    We will be adding more shortcut keys.
    +4. Defined column types. You've got naming rules, but I'd like to be able to define columns as a predefined type, like "Dollar Amount", which would make my column become a number(9.2) or something like that.+
    These are Domains. Select Tools > Domains Administration, and add your domains.
    I'm working on adding short demos for all these features and we'll build these up over time.

  • 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).

  • 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.
    Cheers, APC

  • Function based indexes in Data Modeler 3.0

    Trying to create a function based index in DATA MODELER 3.0 but cannot find a way to do it. When I reverse engineer (import from DATA DICTIONNARY) an existing table that contains such an object, the index appears in the physical model as a regular index. I guess this functionnality is not yet available...
    Thanks.

    Hi,
    You can create a function-based Index by going to the Properties dialog for the Index in the Relational model (not the Physical model). If you select the Index Expression tick box, you can then enter the expression into the Expression text area.

  • 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.

  • 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
