• Renaming of the foreign keys in the relational model

  Hello
  
  
  I'm new to the Data Modeler, we use v 3.0.0.66.5 and Oracle 11 g, and I am trying to build a logic and a relational model for a new application.
  
  We always call our primary keys as the ID, this causes me a problem with my names of foreign keys in the relational model, as they show as ID #. Is it possible to add the abbreviated of the table of the foreign key?
  
  Thanks in advance
  
  Sue

  Yes it is.

  Take a look at the tools > preferences, select Data Modeler > naming Standard > model, you can specify the standard you want to use for your foreign key. You can apply this designation to existing models and all new created FK uses the same model. To apply the standard to existing templates, select the relational model in the browser, right-click to display the context menu and select the menu "apply Naming standards... ».

• 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.

  Best regards

• 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.

• 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

• 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."

• 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

  I don't think there is much you can do about it outside the use of workaround to reload the page until this problem is corrected.

  There is this bug on this problem:

  • http://Bugzilla.DownloadHelper.NET:8080 / show_bug.cgi? id = 642

  I don't know if other extensions download suffer from this issue, as well, so you can try a little more try the website of the add-on and if possible use a different format like WebM, if they are available.

  Also note that not all videos are downloaded and registered correctly. Some may have a size of 0 bytes and fail to download, so, best is to check in downloads of the toolbar Manager in the drop-down list to make sure that the file size is correct (i.e. neither 0 bytes, but a more likely size).
