Sql Developer Data Modeler 3.0 EA1: Export - To reporting schema

When launching Export -> To reporting schema the schema tables are created and messages show that data is being generated but after indicating that it "Exporting Diagrams" I get the following error message:
"Error occurred while exporting to Reporting Schema. See the log file for details."
and all the tables are left empty.
The message log is not indicating that anything went wrong.
What could be the problem?

  • Sql Developer Data Modeler 3.0 EA1: Custom transformation script

    What is the object model used by:
    Tools -> Design Rules -> Transformations
    From looking at the examples (and guessing) I have managed to create ID attributes on all my entities, but how do I set its sequence number or set it as the primary key?
    entities = model.getEntitySet().toArray();
    for (var e = 0; e<entities.length; e++)
    entity = entities[e];
    att = entity.createAttribute();
    att.setName('ID');

    content of XML files:
    1) class described, parent class if there is one
    2)<property .../>
    describes property - set and get method, data type of property, default value
    3) <collection ... />
    describes collection of objects belonging to class - 5 collections are defined in Table.xml - columns, indexes, table check constraints, column groups and spatial definitions
    - get method - to get collection
    - create item method - method of described class used to create item for that collection; so for columns collection table.createColumn() will create column in table
    - other methods - add, move, remove if are defined
    4)other meta data
    definitions in 1) .. 4) are used by Oracle SQL Developer Data Modeler, so it'll be wrong to modify those xml files
    5)<roproperty ../>
    Data Modeler doesn't parse/process these definitions, we decided to not filter them out however you should not rely that much on them
    6)some junk left
    For each object you can set your own properties and they will be persisted (also included in compare/merge in versioning) together with other information for object - look at "template table" example in transformation scripts. Here are methods you can use:
    void setProperty(String key, String value);
         String getProperty(String key);
         boolean hasProperty(String key);
         boolean hasProperty(String key, String value);
         void removeProperty(String key);
         void clearProperties();
         Iterator getPropertyNames();

  • Sql Developer Data Modeler 3.0 EA1: Auto route off

    I admire that the data modeler tries to automatically position relationships and data flows. I am sure it is very hard to automate and I don't think it works very well in this tool.
    So, I am happy that you have the option of turning "auto route" off as I am quite particular about how diagrams should look.
    In the EA1 it seems that even with "auto route" turned of, all connected relationships and dataflows are automatically repositioned as soon as an entity or process box is resized or moved - even the tiniest bit.
    I think the tool should not reposition relationships or dataflows as long as their current position can be maintained after the connected entity/process is resized or moved. When lines have to be moved the tool should try to maintain a position as close to its original position as possible.
    Let me know if there is a way to achieve this.
    Also, when relationships or dataflows have to be repositioned by the tool, I think they should be placed as far away from each other as possible (giving more room for labels). Currently, it seems that the default behavior is to lump relationships and dataflows close together when they connect the same entities or processes.
    / Marc de Oliveira

    it's the same in Data modeler v. 2.0No, in version 2.0 it is not the same. The line stays in place if you move the entity or process in the same direction as the line, eg a vertical line is not repositioned if you move a connected entity or process vertically. The same goes for horizontal lines.
    Also, when resizing the right side or the bottom side of an entity or process, lines connected to it are not repositioned (as long as the box does not become too small).
    You can get lines "more" fixed if you introduce intermediate point Intermediate point? I never heard of that. Where do I learn more about that? I could not find it in the help file.

  • Sql Developer Data Modeler 3.0 EA1: Preference- Naming standard- Templates

    I am trying to figure out how the naming standard templates work.
    When I go to:
    Preference -> Naming standard -> Templates
    It says that 'Attribute Relation' is '{ref entity} {ref attribute}'
    What is the consequence of this?
    I thought, it would mean that when creating a primary key attribute (ID) on an entity (DEPARTMENT), the related "foreign key" attribute (that is automatically created in related detail entities, such as EMPLOYEES) would be named DEPARTMENT ID.
    Instead it is just called ID. Is that the intended behavior?
    - Marc de Oliveira
    Edited by: marc66 on 2010-10-29 05:59

    Marc,
    you should check "FK Attribute name synchronization" setting in "Preferences>Data Modeler>Model>Logical model" - probably it's checked and you cannot change the name of FK attribute.
    I found another bug here - FK attribute doesn't follow changes in referred entity - I logged it in bug database. As workaround you can apply defined templates at entity level (there is button in entity dialog) or for whole logical model (using pop-up menu in the browser).

  • Sql Developer Data Modeler 3.0 EA1: Process order/number

    When opening my version 2.0 model in version 3.0 EA1, the process numbers are as I originally saved them.
    After saving the model as a version 3.0 model (using "Save as..."), when I reopen that version all processes have been reordered on all levels of my model (about 300 processes).
    Actually, it looks like 1 becomes 4, 1.1 becomes 4.4, 1.1.1 becomes 4.4.4 etc...
    Strange behavior. Is there any way to avoid this?

    thanks for feedback. I logged bug for that.

  • Sql Developer Data Modeler 3.0 EA1: Relationship source and target names

    When opening my version 2 model in version 3.0 EA1 the source name and target name of all my 231 relationships are deleted.

    Hi Peter,
    When I examine an XML file for a relation converted from version 2.0, the XML elements "nameOnSource" and "nameOnTarget" are missing in the converted 3.0 EA1 versionthey are not loaded during "open" of older design. If you define them they will go into XML file.

  • Sql Developer Data Modeler 3.0 EA1: Engineering relationships to relational

    When doing 'engineer to relational model' the relationship names are converted directly to foreign key names.
    So, when the relationship between EMPLOYEE and DEPARTMENT is called 'working in' then the generated foreign key is also called 'working in' (not event 'working_in').
    Is it possible to have it engineered to something like 'employee_working_in_department_fk'?
    - Marc de Oliveira

    Obviously, a property called "Plural" and an option for engineering using "Plural" names instead of entity names.
    This would also allow us to have a nice relationship report where we could translate relationships into natural languages, like this:
    Each DEPARTMENT may be employing one or more EMPLOYEES.

  • Import / Export MySQL database in SQL Developer Data Modeler

    Hello,
    I have version 3.1.2.704 of SQL Developer Data Modeler and version 3.2.09 of SQL Developer installed.
    When I´m adding a new connection in SQL Developer, I can choose the MySQL tab an create a connection to a MySQL database.
    The connection test was successful and I can see all tables.
    I use the same JDBC driver for SQL Developer and SQL Developer Data Modeler (mysql-connector-java-5.0.4-bin.jar).
    But there are two problems.
    1. First there is an problem when I want to import from a MySQL database (SQL Developer -> File -> DataModeler -> Import -> DataDictionary).
    After choosing the MySQL connection and pressing the next button an error occurs: CONNECTION_TYPE
    What is the reason?
    2. In SQL Developer Data Modeler I have not the CONNECTION_TYPE problem. But when I want to export DDL, there is no MySQL type selectable, although there is working connection to the MySQL Database. It´s the same in SQL Developer.
    What is the reason?

    Hi,
    Data Modeler does not explicitly support import from MySQL databases, although you can use a JDBC connection to do this.
    Philip described how to set this up in forum message How to connect mySQL for reverve engineering
    There is no MySQL tab in Data Modeler - you should use "JDBC-ODBC Bridge" - "other third party Driver".
    Set URL like : jdbc:mysql://localhost:3306/database_name
    driver Class: com.mysql.jdbc.DriverAlso Data Modeler does not support generation of DDL for MySQL.

  • SQL Developer Data Modeler scripting

    Hi,
    I'm looking for a new modeling software for my company. SQL Developer Data Modeler (SDDM) has many features that fit my requirements. But there are some things that I'm not sure can be done. I work mostly with Oracle databases but still need to support some legacy and non-sql databases. Please look at problems below and tell me if and how those things can be achieved. Any suggestions for alternative solutions are welcome too.
    1) I need to be able process Database Model from command line without human intervention and starting any GUI applications, for example generate DDL script form the model. Does SDDM have any interface for that?
    2) I want to be able to export Database Model into a file in a custom (legacy) format.
    3) SDDM stores database description in xml files. Is xml format defined anywhere? Are xsd schema files availabe?
    4) Is there a SDK available that would allow reading SDDM Database Model into a custom application for further processing?
    5) Is there any Java library available that parses Oracle-11-compatible SQL and PL/SQL?
    Thank you in advance
    Tomasz Grygo

    Hi Kevin,
    thanks for sharing your thoughts. There will be much more advanced find/search facilities in next version of Data Modeler and scripts also will be covered.

  • SQL Developer Data Modeler for SQL Server 2008

    I am not able to connect to my SQL Server 2008 from the SQL Developer Data Modeler. Although I do have jtds-1.2.jar on my machine and I can connect the SQL server through the SQL Developer, but still i'm not able to connect through the data modeler. I need to re-engineer and generate data model for some existing schemas.
    Here is what I'm following:-
    File->Data Modeler -> import -> Data Dictionary -> Add new connection -> JDBC ODBC Bridge -> Other Third Party Driver
    now when I'm giving the JDBC URL and the Driver, It throws an error message stating that the driver could not be found.
    Please let me know what I can do to solve this, any help would be appreciated.
    Regards,
    AVA

    I'd try 1st to connect to the db from sqldeveloper (through jtds - no ODBC involved) and see if you can browse your db and issue sql statements in a worksheet. Then export that connection in xml format and import that from the modeler.

  • SQL Developer Data Modeler not drawing foreign key relationships

    I'm having trouble with SQL Developer Data Modeler when I importa a DDL that has foreign keys. I export DDL files from SQL developer and choose various subsets of files. Sometimes Data Modeler will not recognize a foreign key if I include say a dozen files in the DDL file, but it will if I include just a few. Worse, even if the foreign key is recognized, sometimes it is not drawn in the Data Modeler and I have no way to make it be drawn. To be specific, I import a file containing the DDL for just two tables -- I see the foreign key! I import a file containing the DDL for a dozen tables including the two, I don't! Is there something I am not understanding about when Data Modeler will draw foreign keys or is the tool simply quite buggy?
    Much thanks!
    -ttamon

    Hi Philip,
    I believe I have isolated the problem. Apparently if a field is named "FOREIGN..." it interferes with the tool recognizing foreign keys. Try to import a DDL file containing the following text:
    CREATE TABLE "SAMPLE"."SAMPLE_ONE"
    (     "ID" VARCHAR2(255 CHAR) NOT NULL ENABLE,
         "VALUE" VARCHAR2(255 CHAR),
         PRIMARY KEY ("ID")
    TABLESPACE "SAMPLE_DATA" ;
    CREATE TABLE "SAMPLE"."SAMPLE_TWO"
    (     "ID" VARCHAR2(255 CHAR) NOT NULL ENABLE,
         "FOREIGN_NAME" VARCHAR2(255 CHAR),
         PRIMARY KEY ("ID")
    TABLESPACE "SAMPLE_DATA" ;
    CREATE TABLE "SAMPLE"."SAMPLE_THREE"
    (     "ID" VARCHAR2(255 CHAR) NOT NULL ENABLE,
         "VALUE" VARCHAR2(255 CHAR) NOT NULL ENABLE,
         "ALT_ID" VARCHAR2(255 CHAR),
         PRIMARY KEY ("ID")
    TABLESPACE "SAMPLE_DATA" ENABLE,
         CONSTRAINT "FK6DF8294F2288190D" FOREIGN KEY ("ALT_ID")
         REFERENCES "SAMPLE"."SAMPLE_ONE" ("ID") ENABLE
    TABLESPACE "SAMPLE_DATA" ;
    You will discover the foreign key is not recognized or drawn! Now, if you swap the location of the third table (put it up first) everything works fine. This is how I discovered the problem, various subsets would work, others would not. To confirm the problem is with the field named "FOREIGN_NAME" use the DDL as specified above but change the first letter in the word "FOREIGN" to something else, and it will recognize the foreign key. Looks like a bug to me (took me about 4 hours to isolate this!). I am using Oracle SQL Developer Data Modeler version 2.0.0 Build 584.

    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.
