Engineer to Relational Model - subtypes have no attributes.

Hello.
Engineer to Relational Model tool don`t show attributes of subtype entity. Some bug or feature?
DM 3.1.0.687.

1) Funny, when I dropped the column, and had it recreated by the engineering process, it worked correctly. But re-engineering the old column kept setting it to mandatory even when I manually set it to optional. I have a sense that some of my objects are ignored by the tool... Only when I drop them and recreate them they seem to be recognized. I had the same issue with some entities that consistenetly did not got engineered into my relational model. Only when I created a new ER-diagram and included the same entities they would get engineered into the relational model...
2) Designer did this. When a supertype table was generated in the "one table" mode there would always be a new column called SUBTYPE with a constraint allowing the short names of each subtype as values (ex: for the table PARTIES the SUBTYPE column could only contain the values PERS and ORG). With this in place you could create constraints such as "SUBTYPE = 'PERS' and FIRST_NAME is not null or SUBTYPE = 'ORG' and FIRST_NAME is null".

  • SDDM EA 3.1: Engineer to Relational Model (subtypes)

    It seems that mandatory attributes of entity subtypes become mandatory columns on the corresponding tables even when you engineer to "one table" (the super type).
    In that case I would expect that the column would become optional.
    Even better: a check constraint would verify that the column was not null for records belonging to the originating subtype.

  • Engineer to Relational Model: deleted attributes / undeleted columns

    Hello,
    I am using Datamodeler 3.3.0.744.
    I'm modifying an existing logical model: I'm deleting one or more attributes in an Entity.
    Then I'm executing "Engineer to Relational Model" in oder to get an up to date Relational Model (it existed already).
    The corresponding columns are not deleted in the Relational Model, even though attributes don't exist anymore at the logical level.
    I can't find any option available in order to do that...
    In the previous release (3.1), it worked fine, I could choose the behavior related to the deleted attributes (deleting or not deleting corresponding columns).

    When your forward engineer for a 2nd time you should see a dialog that has the logical on the left and the relational on the right. Entities that are new or changes have an exclamation point next to them. If you open that you will eventually drill down to see the attribute/columns. Where your dropped an attribute it will say "To drop". The check box is unchecked by default. If you check it then when you forward engineer those should get dropped from the associated table.
    Is it not working that way in 3.3?

  • 'Engineer to Relational Model' Dialog does not open

    Steps to reproduce:
    Open Modeler.
    Create a Glossary file with one row as ATTRIBUTE & ATTR as Name & Abbreviation respectively. Check "Incomplete modifier".
    Goto Naming standards under preferences, choose that glossary file. In the logical model, create an entity with one attribute "ATTRIBUTE 1".
    Right click logical model, click 'Engineer to Relational Model', goto General Options tab, check "Apply Name translation". Click Engineer.
    You'll see ATTRIBUTE is not changed to ATTR in the relational model.
    Now right click logical model again, click 'Engineer to Relational Model'. Nothing happens now.
    Goto Naming standards under preferences, double click the glossary file, uncheck Incomplete modifier", save & close.
    Now right click logical model again, click 'Engineer to Relational Model'. It works now. But still the abbreviation does not happen in the relational model.

    Sorry for the very late reply.

  • Sql datamodeler: Engineer to relational model: General Options

    Hello
    When you engineer your logical model to a relational model you get a wizard. In lower part of this wizard byou have several tabs, one of the tabs is called general.
    On this general tab you have check box: Apply Name Translation
    The corresponding help text:
    Apply Name Translation: Controls whether formal names are translated to abbreviated names when the logical model is forward engineered to a relational model, and whether abbreviated names are translated to format names when a relational model is reverse engineered to the logical model. Name translation is applied only for valid names. In addition, translations between the words entity/attribute/key and table/column/index are performed.
    Does anybody have a clue what is meant here?
    Regards Erik

    Erik,
    you have to create glossary (tools>Glossary editor) with words permitted for usage in names in logical model. For each word you can define abbreviation that will be used in transformation process.
    Example:
    Employee - EMP
    Salary - SAL
    Attribute "Employee Salary" will be transformed to column "EMP_SAL".
    You can define preferred abbreviation for entities and attributes and it can be used instead of glossary definitions.
    You also have to set your glossary in "Tools>General Options>Naming standards>Glossary"
    Best regards,
    Philip

  • Logical model fwd engineer to relational model.  Missing FK relationships

    We are experiencing missing relationships in the relational model when engineering from logical model to the relational model. The logical model objects have properly defined primary keys defined. We are using SQL Data Modeler v3.1.700. Any suggestions on how to engineering these relationships without deleting the objects from the relational model.
    Thanks,
    Ed

    Hi Ed,
    I presume you had some relationships in the Logical Model that you were expecting to be engineered to Foreign Key relationships in the Relational Model.
    Please can you provide more detail to help resolve your problem. For example:
    Was the problem on an initial engineer from the logical model? Or on a re-engineer?
    Are you using Entity subtyping in your Logical Model?
    Are there any relevant error messages in the log file? (This is normally file datamodeler.log in folder datamodeler\datamodeler\log.)

  • SQL Datamodeler: engineer to relational model: column names

    Hello
    Suppose I have an attribute called DAY OF BIRTH. Is there a way I can forward engineer this attribute to a column name DAY_OF_BIRTH?
    (I know you could have a coulmn name "day of birth" but thats not what I want)
    Regards Erik

    Hi Erik,
    1) you should check separator settings in General options>Naming Standard -it should be "space" for Logical model and "underscore" for Relational model;
    2) "Apply name translation" should be selected in engineering dialog
    Best regards,
    Philip

  • Warning icon on Engineer to Relational Model screen

    Engineer to Relational Mode l shows warning icon on Attributes, Entities and Logical labels. I don't see the reason.
    Do you know what this warning icon is about and how to tackle it?
    Thanks,
    Prakash

    Hi Prakash,
    Engineer to Relational Mode l shows warning icon on Attributes, Entities and Logical labels. I don't see the reasonThis mean something is changed. You can click on object and should look at details tab. Entity is composite object and it'll get warning mark also if some of components are changed.
    At "compare/copy options" tab you can exclude some properties from compare process if you don't want them to be considered.

  • Engineer to Relational Model case sensitive?

    I developed my database in the Logical Model using Upper and Lower case. When I`m engineering from Logical to Relational Model, it keeps showing me that all atributes have their names wrong and marks them for change in the relational model. Is there a way to inform data modeler to not consider the change in case as differences?

    The thing is that in the Relational Model, all objects are beeing generated in uppercase. When I'm going to update the relational model by enineering from Logical, the program always shows me that the column names are different, when they are not, because the only difference is case! There is already a parameter for the engineering not to test for different case in the entity's name, but no parameter for it in the atribute's name!

  • Sql datamodeler:  Engineer to relational model

    Hello
    is it possible to add a prefix to all your tables?
    Suppose I have entities A, B and C
    Than I would like to have the following tables as a result
    XYZ_AS, XYZ_BS and XYZ_CS
    This according to the CDM standards
    Regards Erik

    Erik,
    it's possible to replace one prefix with another one in current published build (525). It'll be possible to add (replace) prefix to all tables or to tables in certain subview in next release. There won't be possibility to change name A to name XYZ_AS; there will be no problem to change names A and B to XYZ_A and XYZ_B.
    Best regards,

  • Problem with naming of FK attribute when generating the relational model

    I'm usign Data Modeler 4.0 and I have a problem when I engineer from Logical model to Relational model.
    I have a table SUBJECTS with an unique identifier called ID (pk) and a table BOOKS related to SUBJECTS with a relation named FK_SUBJECT_BOOK and FK attribute named ID_SUBJECT.
    When I engineer to Relational Model, it transforms the original FK attribute ID_SUBJECT of the Logical model into an attribute called SUBJECTS_ID in the Relational model.
    How can I mantain the name defined in the Logical model also in the Relational model, without using abbrevation and without applying name translation when generating the relational model?
    Thank you

    I have already tried it. The problem is that if I check the option you mention, then it uses the pk as it is in the related table creating attributes like ID1, ID2, ID3 and so on for all the relations you have.

  • Setting to Select Elements on a Logical Model and Have Them Pre-selected on Engineer Page

    Is there a setting somewhere that would allow me to select objects on a logical model or in the tree view and have them pre-selected in the Engineer to Relational Model window?  Coming from the Designer world  I keep selecting entities in my model and am surprised they are not already selected when I click the engineer icon.  If not I will submit this as an enhancement.  Anyone else interested in this?
    Marcus Bacon

    It is also necessary to click on the check box twice to select/de-select an item.

  • DataModeler: Cannot engineer from logical model to relational model

    Hello,
    I have been trying for a couple of (very frustrating) hours to engineer a very simple logical model to its relational model. The toolbar button (and also menu option) that should do this just does nothing. No errors, no feedback, absolutely nothing!!! However I could engineer a relational model back to its logical model.
    I am using SQL Modeler version 1.5.1 build 525 on Windows Vista. I have closed and restarted the program many times but to no avail. Are there other factors (e.g. anti-virus, JDK etc) that could be responsible? But then why are other parts of the software working but not this one?
    Please kindly send your advice asap so I can proceed. I really like the Modeler and will not want to discard it.
    Thanks,
    Chiedu

    Hi Folks,
    I was able to figure out the likely cause of the problem. The version of Modeler (datamodeling-1.5.1-525-no-jre.zip) I used was downloaded without JRE. The current version of JRE installed on my computer is Java 6 Update 12 (build 1.6.0_12-b04). I suppose the two don't quite work very well together.
    I have now downloaded and installed another version (datamodeling-1.5.1-525.zip) with its own JRE and the problem was resolved.
    My guess is that the problem was due to the incompatibilities that may exist between Data Modeler and the various versions of JRE.
    Thanks.

  • Fwd engineering entity name changes to relational model?

    I changed an entity name in my logical model after generating a relational model. But, I cannot figure out how to have SDDM (3.0.0.665) propagate this change to the relational model.
    In the Engineer To Relational Model screen, if I select the changed entity from the tree view, in the Details pane there is a "Selected" check box next to the Name property (this line shows the discrepancy between logical name and relational name) but I can't check it. Under the Compare/Copy Options tab in that same dialog, the check box next to Name is checked. But, when I forward engineer the name is not changed.

    BTW I just noticed that if I enable "Name Translation" then it seems to work. This is not at all intuitive or obvious, nor does it seem to be explained in the documentation.
    According to the help:
    Apply Name Translation: Controls whether formal names are translated to abbreviated names when the logical model is forward engineered to a relational model, and whether abbreviated names are translated to format names when a relational model is reverse engineered to the logical model. Name translation is applied only for valid names. In addition, translations between the words entity/attribute/key and table/column/index are performed.

  • Unlink Entity From Table on Engineer to Relational

    I imported a table from an Oracle database, engineered it to logical, made changes for SQLServer and now want to engineer it to a new table but the entity is still linked to the oracle version of the table, which has been renamed.  How do I break the synch and create a new table?  I do want to keep the original table in the relational model.

    I have come up with a workaround.  Two Relational Models, one for Oracle and one for MSSS.
