• How to set the attributes of the relationship in the logic model?

  Hello, is it possible to set attributes of the relationship in the logic model (using the sql 3.1.0.683 data Modeller)?
  In my case, I want to set some attributes in a M:M relationship between two tables (for example: start_date and end_date) and then these attributes of the relationship which will be included in the relational model in the form of columns of the table created for solve relations M:M.
  Thank you.

  Hello

  There is no support for attributes in relationship. You should go directly with the entity of the intersection.

• Transformation of table names and a column in the logic model (CCM)

  In addition to my previous question on the transformations of the relational model logical I would like to set for the names of tables like school_units to become SchoolUnit when you do: engineer to the logic model. Ditto for the columns for attributes, i. e. I would like to convert a column of class_sign to classSign.
  With the help of Philip Stoyanov, I could set the mixed case to emphasize the shape of logic to the relational model. But now I can't engineer to the logic model without losing all the work accomplished in the logic model (concerning the designation of entities and attributes).

  Hi Robert,.

  You can try to define "Incomplete modifiers" in your glossary so the name validation will not fail (against the glossary) because it is existing only don't not in the glossary of terms.

  If the name is not recognised as valid then separator is changed, but setting camel case is not considered - I logged a bug about this.

• How to fix the corruption in the logic model?

  Hello

  I have a logic model created in SDDM 3.1.2.704.  I have designed a relational model successfully in the past, but recently when I tried the logic engineer-> relational nothing happens.  I get the following entry in the log file:

  [AWT-EventQueue-0] ERROR MDBAction - java.lang.NullPointerException

  Looking at some other threads, I used the script of processing described here

  3.1.3.709: how to check and fix a design may be corrupted?

  This does not solve my problem, but the output file (generated when I press the engineer to the relational model button) shows the following exception:

  Hello

  but the problem continues (even when the model is reduced to no entity at all!)

  The error that you stated (in engineering and import) is not reached, if there is none of the entities and attributes - this is a specific error, probably in connection with the use of separate types that are removed from the design.

  You can use the search feature to find attributes/columns (logical/relational model) with incorrect data type definition based on the separate type.

  And it is better to move it to Data Modeler 4.0 (833).

  What to look for (example on the logic model - it is the same for the relational model - column):

  (1) to activate the search engine (CTRL-F when logical diagram is active, or the Find icon), switch to advanced mode

  (2) for the attribute "object Type":

  -check the 'Kind of Data Type' line and put DT as search text

  -check the 'Distinct type' line, do not put the text search - it will search attributes without separate type

  -change the operand of OR AND expression

  3) press the ' search ' button.

  If you find some attributes, then you will need to decide what to do with them - to define the data type or delete.

  Ditto for the columns in the relational model.

• How to change the name of "Relationship UID" attribute in the logic model?

  Beginner question here, sorry if it was taken already.
  
  In the logic model in Data Modeler, how can I change an attribute name that is used as a 'UID relationship'?
  
  For example, I create two entities, each with a primary UID called 'id', then create a 1:1 relationship. Each entity will now have an attribute called "id1" marked as a UID of Relation, but I can't find any way to change the name of the attribute. Is there a way?
  
  Thank you.

  Hi GuyM,

  You can check the setting in the preferences - "Data Modeler > model > logic" - the name FK attribute synchronization - clear the check box if you want to manually set the name.

• Entity displayed in the browser, but not displayed in the logic model

  Hello

  In a drawing, I got myself in a situation where two entities are identified in the logic model of the browser, but are not as on the logical schema. I have created the entities, but removed later. However, when I engineer the logic of the relational model, two tables based on the entities are created. I do something wrong, or is this a bug, entities having not correctly deleted for some reason any?

  Kind regards.

  John.

  Hi John,.

  There is a problem in version 4.1.1 of maker of data if some entities or other objects are deleted from a template that has already been registered.  On the next saved position, the saved definition only is not updated correctly, and deleted items reappear on the loading of this registered version.

  This will be addressed in the next version.

  In the meantime, the workaround is to use save them as rather Save to save your template.

• Name of the CRA in the logic model is ignored when the Relatation model engineering

  When I use a bow in my logical model and I'll give it an appropriate name, this name is not used when the report model is generated. Data Modeler named the same arc in the FKArc_1 relationship model for example. And I'll have to rename it manually.

  I think it is a bug and probably not known because it is still occurs in Oracle Developer version 4.1

  Is this a known issue?

  Hi Philippe,.

  Thank you! Problem is solved in the Data Modeler 4.1.1.887

• Design-&gt; engineer to the logic model: Nullpointer Exception

  Hello
  I imported into my physical data as a model of relationship model using import-> data dictionary. Made a subview (in the relational model) and reverse engineered model logic. Worked well.

• How to get the logical tab in the main area of 4.1.2 Data Modeler?

  I just installed Oracle Developer Data Modeler: Version 4.1.2.895.

  I was following section 2.1 development of the logic model

  http://docs.Oracle.com/CD/E48219_01/doc.40/e48205/tut_data_modeling.htm#DMDUG36169

  I used the example of library. I added the areas.

  Then I tried to create the books.

  The document says:

  1. In the main area (right) of the Data Modeler window, click the logical tab.
  2. Click the icon of the new entity.
     
     

  But I don't see the logical TAB on the right side at all.

  I see the Start Page. On the far right is the browser window. Basically, I see Messages - Log.

  On the left side, I have the browser window.

  Can someone tell me please how to get the logical TAB in the main area?

  Thanks in advance.

  Hello!

  In the browser with the right button on the logic model and select view.

  I hope this helps!

• ODM 4.0.2.840, how do I see the data in a logical model

  Hello

  I started with the ODM by a new entity in a logic model.

  I can't find the way to see the data type in the box. I see that the attribute names.

  Thanks in advance

  Hello

  If you change the notation for the logic model Bachman or in notation using Engineering Information you should be able to see the data type in the box of the entity.

  To change the rating, right-click on a blank area of the diagram and select rating in the menu.

  When you use these ratings, you can choose whether or not the data type is indicated using the menu to see the details when you right click on a blank area of the diagram.  This menu contains an entry of data type.

• can we create specific diagrams of logic model for the relational model?

  Hi-
  
  I created several diagrams of relational model. I want to create the logical data model diagram for each of the relational model.
  Is it possible to do?
  
  Currently, it is always associated with a logical data model diagram. When I create LD for the 2nd, it is always update the same diagram.
  Please let me know.

  Hello

  Yes you can have the diagram in the logic model. Check there titled "Subview as" at the top right of dialogue engineering - select it and subview will be created in the logic model corresponding to the main schema to your relational model.

  In addition to the definition of the logical = object that the script against the relational model. To prove this, have a script to collect all the table names, and have different names in the two models.

  There are scripts works on the logic model - ability to auto create a primary key column when creating an entity?

• SQL Developer Data Modeler: logic model, impossible to create the arc

  I have a logic model in SQL Developer Data Modeler. Entity A has two 'incoming' relations of foreign entities B and C keys. The two releations have the same cardinality and optionality. I want to place the two relationships in an arc. I see the buttons in my menu to the toolbar, but they are not enabled. Even when I select the two relationships is not.
  
  What is the logic model for the relational model creates foreign keys. These foreign keys can be selected and when I do that the button "create a new arc" in the toolbar of the model relationship is enabled.
  
  What Miss me in the logic model...? The documentation does not give a clue.

  Erik,

  You must select the relationships and the entity, then the CRA buttons are enabled.

• Is engineer to the relational model - possible to force a crash of the relational model

  Hello

  Is it possible to force a crash of a relational model existing at execution of the engineer to the relational model? Example: If I change the order of an attribute (in an entity) and do an engineer to the relational model, the order of the columns (in the table) remains the same. Although as said, I changed it in the logic model. It is with my current settings. I have not found a property to the order 'RM keep' or 'forcing the crash of the RM.

  How can I make such a change to the relational model?

  Best regards

  Robert

  Hi Robert,.

  support - Yes it is in the direction opposite - order of the attributes of logic model is applied to the columns of the tables.

  On the search feature:

  http://www.thatjeffsmith.com/archive/2015/07/search-and-replace-in-Oracle-SQL-Developer-Data-Modeler/

  https://apexapps.Oracle.com/pls/Apex/f?p=44785:24:no:P24_CONTENT_ID, P24_PREV_PAGE:6623, 2

  and here Oracle Sql Developer Data Modeling 3 3 new features

  shortly:

  (1) do simple search - put asterisk and press enter

  2) filter on the tables

  (3) properties of the Commons game - there is a bug on this feature in 4.1.888 but it will do the job

  BTW - DM is distributed with the transformation (named "Columns order") script that reorders columns in a specific way - PK columns, the columns FK, the required and optional columns.

  At the end of the treatment for each table, it sets this property to false - table.setAllowColumnReorder (false);

  So, you can do the same thing with the scripts - there are examples that you can use as a starting point.

• Dm3.0 ai2: Logic model relationship cardinality: Optional Source mislabeled?

  In the logic model, created a relationship 1: n of non-identification between 2 - Parent and child entities. Parent is 1: n with the child. The two entities have a primary key of unique column - parent_id, child_id respectively. I would like to apply LAUGHED as a parent can exist without children, but a child can not exist without a parent.
  
  In the logic model, the properties of the relationship, the cardinality - I change the checkboxes Optional Source and optional target to achieve my goal. I first tried to target control optional and leaving Source option unchecked. Then I have a physical model of the engineer and generate DDL for Oracle 11 g I get this constraint:

  SQL>ALTER TABLE child
    2      ADD CONSTRAINT Relation_1 FOREIGN KEY
    3      (
    4       parent_id
    5      )
    6      REFERENCES parent
    7      (
    8       parent_id
    9      )
   10      ON DELETE SET NULL
   11  ;
  
  Table altered.

  Here's a test case that illustrates this isn't quite what I wanted (starting with two empty tables):

  SQL>
  SQL>
  SQL>insert into parent (parent_id) values (1);
  
  1 row created.
  
  SQL>commit;
  
  Commit complete.
  
  SQL>
  SQL>insert into child (child_id, parent_id) values (901, 1);
  
  1 row created.
  
  SQL>commit;
  
  Commit complete.
  
  SQL>
  SQL>delete from parent;
  delete from parent
              *
  ERROR at line 1:
  ORA-01407: cannot update ("ODS_ETL_OWNER"."CHILD"."PARENT_ID") to NULL

  If I have Source checked and unverified optional target, a physical model of the engineer and generate DDL for Oracle 11 g I get this constraint that produces the effect with my test scenario:

  SQL>ALTER TABLE child
    2      ADD CONSTRAINT Relation_1 FOREIGN KEY
    3      (
    4       parent_id
    5      )
    6      REFERENCES parent
    7      (
    8       parent_id
    9      )
   10  ;
  
  Table altered.
  
  SQL>
  SQL>insert into parent (parent_id) values (1);
  
  1 row created.
  
  SQL>commit;
  
  Commit complete.
  
  SQL>
  SQL>insert into child (child_id, parent_id) values (901, 1);
  
  1 row created.
  
  SQL>commit;
  
  Commit complete.
  
  SQL>
  SQL>delete from parent;
  delete from parent
  *
  ERROR at line 1:
  ORA-02292: integrity constraint (ODS_ETL_OWNER.RELATION_1) violated - child
  record found

  But this seems backwards - and documentation reads as if it were backward. Am I missing something, or are the Source option and checkboxes optional target mislabeled? Should be Manditory Source and target mandatory?

  I would like to apply LAUGHED as a parent can exist without children, but a child can not exist without a parent.

  You must set as optional parent and the child to be mandatory.

  Am I missing something, or are the Source option and checkboxes optional target mislabeled? Should be Manditory Source and target mandatory?

  There is a relationship and both ends of that relationship and you can set for each end whether it is optional or not. And who saw directly using ratings of Barker. Place of optionality source and target is to be exchanged on the diagram if you use the notation IE.
  I expected that a part of cardinality may be more confusing to you because at the end of the source define you the cardinality of the target, but it seems that you have no problem with that.
