Engineering logical subtypes to Relational model

I have a logical model with subtype (box in box). When I forward engineer to a relational model there is nothing in the model to represent the subtypes. I was expecting (as in old Designer) to see a differentiator "type" column to be generated with a column check constraint based on my subtypes. In the logical model I selected "single table" as the implementation strategy.
Note I also have these entities tagged as Dimensions and did notice the engineering dialog showed the substypes as hierarchies too.
Am I missing a a preference setting somewhere?

Hi Kent,
I was expecting (as in old Designer) to see a differentiator "type" column to be generated support for that will be added later.
Note I also have these entities tagged as Dimensionswhat do you expect - if you change implementation from "single table" to something else you'll get tables also classified as dimension, no other magic will be involved
and did notice the engineering dialog showed the substypes as hierarchies tooI don't see your point here.

  • Strange mapping of Boolean from Logical to DB2 Relational model

    Hi guys,
    Using most recent version of Data Modeler (3.3.0.747) I notice strange behavior:
    Attribute, declared as Boolean in Logical model is engineered to a column, with type CHAR(1) in Relational Model, when "RDBMS Type" is Oracle, but when "RDBMS Type" is "DB2", column type is CHAR(254)
    Is this a bug or a feature?
    Is there any way, where I can control type mapping between logical and relational model?
    Well, I can just go and change CHAR(254) to CHAR(1) all over my Relational Model, but this is pretty frustrating.

    Hi Stoyan,
    Is there any way, where I can control type mapping between logical and relational model?In fact mapping is between logical data type and database native types - Tools>Types Administration.
    You need to change mapping for Boolean logical data type - check "size" check box and put value in text field to define default size. Default size will be used when there is no explicitly defined size in column/domain definition.

  • Problem when engineering to relational model

    I have modeled everything in Logical model and then engineered it to the relational model. Now I have to make some changes, and I'm doing them in Logical model. When I'm engineering it to Relational, although I just altered one single item, I see that it's also bringing some other entities as altered. Inpecting these I see that all of them relate to identifying foreign keys with more than one column. For examplo, I have an entity with 2 columns as primary key, and a second entity with an identifying foreign key to the first, and a third column, based on a sequence, which, all three of them, are the second tables primary key. Everything is OK, I haven't changed anything on any of these entities, but when I'm engineering to relational, it creates a duplicate of one of the columns on the relational model, and alters it's name appendig a number 1 after it. If I try engineering again, it is going to create another column appending a number 2 and so on.... I think this is a bug.... am I right?
    My alternate solution is to drop the foreign key on the relational model, thus dropping both columns, and then engineering from Logical again. Everything keeps working fine, until I close my model. When I open it again, the same problem reappears....

    Philip,
    Sorry for my too late reply, as I forgot to flag this discussion to notify me via e-mail. Thanks for your response, but I was actually using DM 4.0.1.836 and this issue still persisted.
    I just downloaded DM 4.0.2.840, and the issue still persists. I just opened my original model and, without making any changes, tried to forward engineer from logical to relational, and it brings up differences on exactly the same tables.
    Wolf
    P.S.: I've gone through the motions of dropping the FKs on the relational model, dropping any orphaned columns (from these FKs) and re-engineering. Afterwards, I saved and closed all models, closed the application, opened it again and opened my model and the issue persists.
    I also created a new model, with some tables using the same principles, and no error occurred, although in this new model I didn't create a physical model.
    Is it possible that something is wrong with my original model?

  • Error engineering logical data model to relational data model -- name column hierarchies

    Hello,
    I have three entities, Entity1 is logical only , entity2 is a subtype of entity1, and entity3 is a subtype of entity1.
    Entity1 has the abbreviation ( PRUE) and entity1 has three atributes ( PRUE_PPPPPP, PRUE_OOOOO).
    when I make engineering the columns resulting in entity2 and entity3 are PRUE_PRUE_PPPPPP and PRUE_PRUE_OOOOO
    I have unchecked the options apply translations of names and preferred use abbreviations in general options (engineering)
    and the tree comparison is the right name (While the result in the relational model is incorrect)
    ¿Any help?

  • Engineering to and from logical and relational models

    I have tried to modify a logical model entity by adding an attribute or two, tried to engineer to the associated relational model, only to have the engineering process create a brand new table rather than adding the new column or two to the existing table.
    Creating the column in the table first and engineering back to the logical model didn't appear to do anything, although I might have missed a new logical entity.
    Is this how the product is supposed to work?

    Hello,
    I'm sorry but your steps are not evident for me.How it works - you can start from table or entity, it doesn't matter which one is first you should be able to synchronize changes.
    Let's assume you have two relational models RM1 and RM2 and table TABLE_1 in RM1. if you engineer RM1 to logical model then entity will be created that corresponds to TABLE_1 in RM1 (and it will be named TABLE_1 if you don't use glossary that provides replacement of TABLE with something else).
    You can add attribute to entity and engineer logical model to other relational model (RM2) - new table will be created in RM2.
    Add one more attribute to entity and engineer to RM1 - two attributes will appear showing that two new columns can be created - they are not selected and you have to select them if you want columns to be created.
    You'll get only one new attribute (column) if you engineer to RM2 - the first added attributed is already there as column.
    Of course you can add columns in tables and can synchronize them with entity in logical model.

  • Engineering from relational model to logical model duplicated views

    Hi all,
    Several times, also in different projects, when I engineer from relational model to the logical model, the comparator tool show me de differences.
    In these differences there are no view differences, but when I finish the process everything goes right except that in the logical model under views, I see all the views duplicated with [view_name]v1.
    I've tried not selecting the view checkbox, in the compare dialog,but I get duplicated views also.
    I don't know fir sue if this happens with table also.
    What can I do to solve this problem? Is this a bug?
    Edited by: morfeo8marc on 04-abr-2012 2:02

    The problem is fixed in DM 3.1.1.703 and it's published. You can run following script and save design in order to get mappings for views recovered.
    Philip
    lmodel = model.getDesign().getLogicalDesign();
    rmodels = model.getDesign().getRelationalDesigns().toArray();
    for (var i = 0; i < rmodels.length; i++) {
    rm = rmodels;
    eviews = lmodel.getEntityViewSet().toArray();
    for (var k = 0; k < eviews.length; k++) {
    ev = eviews[k];
    tv = rm.getTableViewSet().getObjectByID(ev.getGeneratorID());

  • DM3.0 EA2: Filter engineering changes between logical and relational model

    Hi,
    when I am engineering changes between logial and relational model there are some issues at filter handling for me:
    - When the filter "Show Modified Objects" is activated, the filter works only on the first level, e.g. on Entity level. On attribute level all attributes are displayed, not only the attributes which have really been modified. It is possible, to show on every level only the really modified objects?
    - I think, selecting a Filter condition is circuitous. All filter conditions except "Show All Objects" keeps activated when I choose another condition. So I have to deactivate "Show Deleted Objects" when I want to see only the modified objects. It is possible to choose another control element for filtering, e.g. disjunctive radio buttons?
    I am running Data Modeler on Windows XP with german localization and the JDK 1.6.0_11 from Oracle SQL Developer.

    I logged bug for that.

  • 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.)

  • Why are tables disappearing when Engineering Logical Entity Hierarchies to Relational

    Tables disappearing when Engineering Entity Hierarchies Logical to Relational
    We are using 4.0.3.  We have a model with imported from Designer with a number of Entity Hierarchies. 
    The model has a three of entity hierarchies (ORD, PLAN and STEP) each with a number of subtypes.  Single tables are built for each of the entity hierarchies and are called (ORD, PLAN and STEP).
    If I make a change within an entity hierarchy in the subtype (ORD_METRIC) and forward engineer the only ORD entity hierarchy as single table, the table ORD gets update but the tables STEP and PLAN disappears from the Relational table list.    They only remain if I select all three entity hierarchies when engineering to relational.
    Have I a missed selecting an option?

    Hi,
    in current implementation for entity hierarchies (only) - "engineering to" flag is used also as implementation flag for entity, i.e. if entity is not set to be engineered there will be no implementation as table for that entity in relational model. Attributes of such entity will be implemented in another entity engineered to relational model. If no one entity from hierarchy is engineered (no implementation) then existing corresponding table(s) will be removed.
    We'll change it in the future to be less confusing.

  • 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.
    / Marc de Oliveira

    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".

  • 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.

  • Engineering (logical to relational) does not do name translation/variable population as expected

    I am using OSDDM 3.3.0.747.
    I have set up the following template formats, e.g.
    Foreign Key: {table}_FK{seq nr}
    Unique Constraint: {table}_UK{seq nr}
    When I engineer from logical to relational model, I get generated names like the following:
    {TABLE}_FK3
    TENANTS_UK{SEQ_NR}
    TENANTS_UK{SEQ_NR}v1
    How do I stop this from happening?

    Hi,
    thanks for reporting the problem. I logged a bug for problem related to Unique constraint.
    For foreign key - there is no variable {table} in template  for FK. You can use {child} or {child abbr} instead.
    As workaround for Unique constraint - you can apply naming standards for whole relational model - "Apply Naming standards for Keys and Constraint" in context menu for relational model in browser, or at table level - table dialog

  • 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.

  • Engineer between Logical Model and Relational Model

    I am trying to update changes from one model to the other but there are dublicate entries generated instead of updates.
    The Logical Model was imported from Oracle Designer, the Relational Model was imported from data dictionary.
    Our rule is, that the name of Entities/Tables and Attribute/Columns are identical.
    So I changed the Naming Standard of the Logical Model in Preferences
    from Separator = Space to Separator = Character with char = Underline.
    If the entity is not existing, it is created with the correct name.
    If the entity exists, a new entity is created with Namev1.
    The same happens when I try to update changes in the other direction.
    How can I achieve that the existing entity (or table) is updated and not a new one is created?
    Or in other words, is there a way to link entities to corresponding tables?
    Walter

    Hi Walter,
    The Logical Model was imported from Oracle Designer, the Relational Model was imported from data dictionaryit's good to import entities and related tables from Designer repository together. Data Modeler will import the link between them and use that link in synchronization between logical and relational model. After that you can import details for physical model from database.
    If you don't have tables in Designer repository and keep the same names for entities, attributes, tables and columns then you can engineer logical model to relational and import details from database.
