Renaming of the foreign keys in the relational model

• Term plurals changes the name of the foreign key in the relational model

  Hello

  I use a glossary with plurals for entities such as Budget turned to the budgets of the table in the relational model. Unfortunately (for me) it also changes the name of the foreign key. In the related entity, an attribute (for example) is Budget_fiscal year, I expect in the relational model, being the same, but it is transformed into budgets_fiscal_year (budgets in the plural rather than keep him in singular form).

  How can I avoid any change in the attribute names (in the process of engineering in the relational model) but always turn the names of entities from the singular to the plural names for tables?

  Thank you and best regards

  Robert

  Hi Philippe

  Your suggestion 1) works - thank you! budgets_fiscal_year is the attribute of pk exercise in my budget of the entity. It seems a standard behavior of the Data Modeler to compose the UID of the relationship of budgets_fiscal_year (for some reason, this column is not taken the logical model, but the relational model). I would prefer that it be appointed budget_fiscal_year.

  I have not defined any parameter for this (intentionally). But maybe somewhere there by default. Could you tell me where the design parameters in Data Modeler to learn how to configure the definitions mentioned in 2)?

  As I'm always busy with the model of reverse engineering data, I'll wait for DM 4.1.1.888.

• Exclude foreign keys from the relational model comparison

  Hello!

  Is it possible to exclude foreign keys for comparison when comparing relational models?

  It's the same and when inporting dictionary of data in the relational model.

  Thank you very much for the help!

  Kind regards

  Dimitar Angelov

  Hi Dimitar,

  Yes it is possible to do using "generate DDL' flag - there is an option in the dialog box"compare models"- tab" Options > compare Options '-C' is a checkbox "use generate DDL settings to filter objects.

  You must make a DDL generation with open physical model that will be used - in the DDL generation options you can deselect items you don't want to have in comparison. You can save as a configuration of generation of DDL or simply do it before the comparison.

  After comparing models of dialog, you can check "Use generate DDL settings to filter objects" box to check (and probably to load a configuration of generation of DDL) and use the buton "refresh trees."

  You can use this method to filter the tables, constraints PK and UK, index, constraints FK and the views.

• Show only the keys in the relational model

  I just got 3.1 and I noticed that the new features announced that:
  
  Relational - Option to display only the columns of the primary key, Unique key and foreign key
  
  I looked around and I can't find a way to show just keys only in my relational model (imported data dictionary). It shows the full column list, and it identifies the PK and FK columns in the relational model.
  
  Anyone know where to find this option?

  Right mouse in the area of model

  In the context menu, select 'view details '.

  Then expand and select 'PK, FK, UK columns only.

  It will not resize the objects in the model, so if you want to save space in your diagram, right-click and choose "Resize visible objects."

  Here's a quick look at how it works
  http://www.thatjeffsmith.com/archive/2011/12/SQL-Developer-Data-Modeler-quick-tip-hide-and-resize/

  Note that the screenshot is EA 3.1 so the context menu to "view details" is a little different, but it's the same idea.

• Change the cardinality of the relationship in the relational model

  With the help of SDDM 3.3.0.747.

  When a foreign key relationship is defined between two tables in the relational model, the cardinality symbol as one-to-many default.

  Is it possible to specify the relationship and so the cardinality symbol, must be something different, for example under the unique name?

  Hi Mark,

  You must define a unique constraint or a unique index on the columns FK and you will get 1:1 line

• Cardinality in the relationship of the relational model FK

  I use the latest data model and tryint to set the cardinality and the required property of a FK relationship. At first I thought its impossible to in the relational model and only possible in logic, but I can see this is done in diagrams PDF file 'schema \datamodeler\reports\Reporting schemas. How can I do? Thank you.

  I use the latest data Modeler

  You can download 3.0 ai2 it was released a few hours ago.
  You can set mandatory (optional) in the foreign key dialog box - double click on the line FK or use 'Properties' on the menu of the FK.
  There are no other parameters of cardinality for foreign keys. However in ai2 they will be shown without leg if you assign the primary/unique constraint on columns FK only.

• Engineer selectively the relational model

  Hello

  I want to include a few tables on an existing relational model, however, even if I select only these two entities on my logic model, whenever I try to add in my existing relational model, it is updated and I lose the layout of the relational model.

  Is it possible to add an existing relational model-specific logical objects, without losing the current provision?

  Thank you

• 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.

  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.

• Entity and attribute transformation of names (case-sensitive) to the relational model

  Hello

  For the names of entities and attributes, I would use camel casing, e. g. AccessRightGroup (or the right access group) and its translation to the relational model in the Table name access_right_groups. I found, I can do in the entity properties > General > abbreviation preferred by writing the name of the table you want in this area. But I guess that there is a more elegant way by setting that breaks are transformed into small capital and underlined and entity (set) becomes plural as table. Is there such a possibility?

  How that would make the camel case attributes?

  Best regards, Robert

  Hi Robert,.

  case-sensitive, you must set 'Title case' as a separator for logic model in the design properties dialog box "settings > naming standards '-c' is for this form of the names AccessRightGroup; for group of access rights that you need not change anything - the default separator is set to 'space '.

  For the plural in the relational model, you need a glossary with defined plurals - however it only works for the entity name unique term. I logged an ER to change this.

  Tiny in a relational model - well you must set to relational model - in the Properties dialog box - "(Naming options > Table, cas de caractères...-mis à baisser et le nom sera mis dans cette affaire àle cours de la transformation) - otherwise you always can use the script provided with Data Modeler to convert the names of all the lower/upper cases."

• 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.

• 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

• Synchronization of the comments of the column from the relational model to the data dictionary?

  I changed/added comments of column to a table in my relational model. When I try to sync the database data dictionary changes are never included the observations of the new column. In fact, I see that the values in the field 'Commentary in RDBMS' are different in the preview window to compare, but the line is not highlighted in red I guess that, in fact it is even dimmed. Also, I can not check the check box "selected".

  Is there a way to get comments to synchronize? I don't miss any option that I first? Is this a bug or an expected behavior?

  I use the version 4.0.3 x 64 of the Data Modeler.

  Any help would be appreciated,

  Charlie

  Hi Charlie,

  but the line is not highlighted in red I guess that in fact it is grayed out even.

  "that means property is excluded from the comparison - the same dialog box click on tab -" Options > properties filters '-you can control the properties to include in compare it it is to say ' comment in RDBMS ' must be checked.

  Press the button "Refresh trees" after the properties are set correctly.

• Data Modeler: changing attribute Table grayed out (in the relational model)

  I use SQL Developer Data model version 2.0.0 build 584.
  
  I have a relational model of appr. 30 paintings. For some tables, the display of attributes is grayed out, not allowing not of any change of the values. I have a feeling that this was due to an import/merge views of database, but for me this quite annoying because it prevents modelling activities further on these tables.
  
  Does anyone have an idea what could be the reason for this? More importantly: how to remedy this situation?
  
  Mark

  Hi Mark,

  Does anyone have an idea what could be the reason for this

  the reason is probably the difference in design name and name in the next item in the XML of the table:
  
  It is interesting how you did this.

  More importantly: how to remedy this situation?

  You can try ' Save as ' to save the design in a different directory.
