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

  • 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.

  • 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.

  • Domains usage in SQL Developer data MODELER

    Hi,
    I'm trying to understand how to use Domains in Oracle SQL Developer Data Modeler. We use version 3.1.3 .  before I used Toad Modeler  where domains are just part of your main design.
    Oracle data modeler has some different concept.
    let's assume I'm working on 2 designs:  DesignA and DesignB that include relational models.
    DesignA and Design B should use domains but list of domains in design A is very different than in design B.
    Default domain file is located on c: drive where SqlModeler is installed. It is obviously unacceptable , so I need to change Default System Type directory in preferences.
    And of course I want to have different domain directories for DESIGN A and DESIGN B.
    So when I open design A then I changed   Default System Type directory  let's say to x:\AAA.   Then i close design A and open Design B and change Default System Type directory to x:\BBB
    I checked folders AAA and BBB and they  have necessary XML files there:  defaultdomains.xml, defaultRFDBSSites and so on....
    Now questions:
    can I rename defaultdomains.xls to something else like AAAdomains.xls?  Domain administration can edit any domain file with any name , but how  can I associate certain domain file with my design?  My wish , when I open my design , then corresponding domain file will be open automatically.  Is it possible?
    If I open 2 designs in Sql Modeler and switch between designs  then corresponding domain files should be changed automatically as well.  Currently   I shouldn't forget to change default System Type directory every time when I switch models.  Is it the only way to handle it?
    Thanks
    vitaliy

    Hi Vitaliy,
    We use version 3.1.3
    I recommend always to use the latest version. If you don't want to use beta (DM 4.0 EA is out) you can use DM 3.3.
    Otherwise Oracle SQL Developer Data Modeler supports two types of domains:
    1) DM installation domains - those in file defaultdomains.xml
    2) Design level domains - they are stored in design directories and are visible to particular design only. They can be created in following ways:
    2.1 Manually - there is a property "Domains file" and you id it's not set "defaultdomains" domain will become design level domain and will be stored in file with provided name (without .xml extension)
    You can change later the file for design level domains, however you cannot change file for domain already in defaultdomains.xml.
    2.2 Using types to domains wizard you can generate design level domains
    2.3 Design level domains are created during import of  DDL files (controlled in preferences)
    2.4 You can import domains from specific file with domains using "File>Import>Domains" - you need to rename the source file if it's named defaultdomains.xml otherwise you'll get domains as installation domains
    If the list with domains is too long you can define  a list with preferred domains (or/and logical types) in "Preferences>Data Modeler>Model" and you can use shorter list in Table/Entity dialog if check "Preferred" check box next to "Type:" combo box.
    If I open 2 designs in Sql Modeler and switch between designs  then corresponding domain files should be changed automatically as well
    If you open 2 designs in one instance of DM they will use the same file with default domains i.e. you'll lose domains in one of design depending of setting for "system data type directory". You need to go with design level domains.

  • 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).

    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,

    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.

    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

    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

    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

    I tried every thing except completely re-install my whole PC.

  • Sql Developer Data Modeler all domains lost after changing to version 3.0

Any help would be appreciated.Copy file defaultdomains.xml from DM 2.0 installation to "sqldeveloper\sqldeveloper\extensions\oracle.datamodeler\types" directory (if you use version in SQL Developer) or to
    "datamodeler\datamodeler\types" if you use standalone DM 3.0.

    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.

    Hello,
    you can create sequences and triggers in Oracle physical model - you can find triggers under table node (physical model).
    However it'll be better for you to do development of triggers in SQL Developer. After development of triggers is over you can put your triggers in data modeling physical model.

  • Oracle sql developer Data Modeler -er diagram

    Hi
    I tried to Oracle sql developer data modeler for show relational ER diagrams.
    Tables are came on data modeler but not shown relations between tables.
    like this
    How can show relations between tables?
    http://i54.tinypic.com/30wxq1e.jpg

    SDDM cannot create an ER diagram with only simple table definitions. It requires that primary keys (PKs) and foreign keys (FKs) be defined first. My guess is you imported these table designs from an existing database. If so, that database does not contain those constraints. (I have found this to be an issue in many organizations over the last 20 years - including my current job). You will have to determine:
    1. The PKs for each table (either via data profiling or talk to someone who "knows" what they are supposed to be, or by reading application logic/code used to manage the tables).
    2. The FKs between the tables. You may be able to guess some of that based on column names, otherwise you will have to figure them out (same as above)
    Then you can update the model in SDDM with the PK definiions (manually). You must do that first before you draw in the FKs between the tables. Now if you want a true Entity Relationship model you need create a logical model from this relational model. The SDDM utility for that will convert the tables to entities and the FKs to relationships.
    I have the basic steps with screen shots outlined in a presentation I gave in Denver in late 2009. It was an earlier version of SDDM but the basics are the same. You can find the presentation is here: http://www.rmoug.org/QEW2009/SQL%20Developer%20Data%20Modeler%20(2).pdf. Start at about slide 12.

  • 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)

Maybe you are looking for
