Foreign key Mapping based on Data - in SQL Developer Data modeler

Team
Do SQL Developer Data modeler supports Foreign Key mapping based on the Data in the Schema rather defined at the DDL ? For e.g if we implement a Objects Relation ship mapping in Data base, we don't define Foreign keys at table creation.
Toad does this feature through "AUTOMATIC FOREIGN KEYS MAPPING IN TOAD DATA MODELER" more info at (http://toadworld.com/Blogs/tabid/67/EntryId/905/Automatic-Foreign-Keys-Mapping-in-Toad-Data-Modeler.aspx)
any one know how to implement through some scripts also helps me
Regards

If you have table PKs defined and the candidate columns match those PK columns, then you can use the Discover Foreign Keys utility. Right mouse over the relational model name (node) in the left browser. It is about half way down the menu. I did a blog post about it last week on kentgraziano.com.

SQL Developer Data Modeler - Relation to Foreign Key Generation

SQL Developer Data Modeler 2.0.0 Build 584.
I am having trouble with Relations to Foreign Keys when Forward Engineering a Relational Model from a Logical Model.
First of all, the Naming Standard is not applied to the Foreign Keys when I perform the Engineer to Relational Model.
So I right click on the Relational Model from the Browser and Apply Naming Standards to Keys and Constraints.
I uncheck everything but Foreign Keys.
Now, Foreign Keys are named according to my Naming Standards.
However, this process also performs renames on the Column Foreign Keys even though I specifically unchecked that option.
This appears to be a BUG in the software and I haven't found a way around it.
I tried using {column} instead of {ref column} in the Naming Standard Template for Column Foreign Key, but that simply resulted in renaming my columns to "{column}".
Please confirm and/or let me know of any work-around for this.
Thanks,
Dan

Hi Philip,
Thanks for the reply.
Is this recorded as a bug to be addressed in the future?
Should I submit this problem via Oracle Support?
The other work-around I came up with is to override every Relation name in the Logical Model with the name I want to use in the Relational Model.
When the Relational Model is Engineered, this becomes my Foreign Key name.
Of course, this is not how I want to do things, so I am hoping for a bug fix someday.
Regards,
Dan

SQL Developer Data Modeler not drawing foreign key relationships

I'm having trouble with SQL Developer Data Modeler when I importa a DDL that has foreign keys. I export DDL files from SQL developer and choose various subsets of files. Sometimes Data Modeler will not recognize a foreign key if I include say a dozen files in the DDL file, but it will if I include just a few. Worse, even if the foreign key is recognized, sometimes it is not drawn in the Data Modeler and I have no way to make it be drawn. To be specific, I import a file containing the DDL for just two tables -- I see the foreign key! I import a file containing the DDL for a dozen tables including the two, I don't! Is there something I am not understanding about when Data Modeler will draw foreign keys or is the tool simply quite buggy?
Much thanks!

Hi Philip,
I believe I have isolated the problem. Apparently if a field is named "FOREIGN..." it interferes with the tool recognizing foreign keys. Try to import a DDL file containing the following text:
CREATE TABLE "SAMPLE"."SAMPLE_ONE"
(     "ID" VARCHAR2(255 CHAR) NOT NULL ENABLE,
     "VALUE" VARCHAR2(255 CHAR),
     PRIMARY KEY ("ID")
TABLESPACE "SAMPLE_DATA" ;
CREATE TABLE "SAMPLE"."SAMPLE_TWO"
(     "ID" VARCHAR2(255 CHAR) NOT NULL ENABLE,
     "FOREIGN_NAME" VARCHAR2(255 CHAR),
     PRIMARY KEY ("ID")
TABLESPACE "SAMPLE_DATA" ;
CREATE TABLE "SAMPLE"."SAMPLE_THREE"
(     "ID" VARCHAR2(255 CHAR) NOT NULL ENABLE,
     "VALUE" VARCHAR2(255 CHAR) NOT NULL ENABLE,
     "ALT_ID" VARCHAR2(255 CHAR),
     PRIMARY KEY ("ID")
TABLESPACE "SAMPLE_DATA" ENABLE,
     CONSTRAINT "FK6DF8294F2288190D" FOREIGN KEY ("ALT_ID")
     REFERENCES "SAMPLE"."SAMPLE_ONE" ("ID") ENABLE
TABLESPACE "SAMPLE_DATA" ;
You will discover the foreign key is not recognized or drawn! Now, if you swap the location of the third table (put it up first) everything works fine. This is how I discovered the problem, various subsets would work, others would not. To confirm the problem is with the field named "FOREIGN_NAME" use the DDL as specified above but change the first letter in the word "FOREIGN" to something else, and it will recognize the foreign key. Looks like a bug to me (took me about 4 hours to isolate this!). I am using Oracle SQL Developer Data Modeler version 2.0.0 Build 584.

New SQL Developer Data Modeler : name of attributes of foreign key

Hi,
with designer the name of column of foreign key was the " short name of entity/table master" + "_" + "the name of column attribute of the master table" .
Instead in the sql developer D.M. the system uses directly the name of the column/attribute of the master table and if the name exists in the slave table it uses a number to distinguish them .
So, if i have a table with short name gp and a primmary key id and a slave table with even a column id ,
with the D.M i'll have in the slave table a column named id2; in the designer instead the new column is gp_id .
Is possible to have the same behavior of designer even in the SQL Developer Data Modeler ?
Regards
Gianpaolo Giliberto

Hi Gianpaolo,
the columns of foreign keys are generated without the short name of master tablehow do you define that short name? Table and column have property "Abbreviation" - short name should be set there. You need also to set naming templates in "General Options>Naming Standard>Templates". Templates will be used when foreign key is created or you can apply them in Table dialog or for whole relational model using pop-up menu in the browser.
no foreign key index is generated on foreign key columns I assume, you want it for DDL generation only - this is controlled in "General Options>DDL"
Regards,
Philip

SQL Developer Data Modeler, Repository or file based?

As announced, in a next release of SQL Developer Data Modeler it wil be repository based. Ok that is nice. But what does it mean for the current possibility to store your work in files. Will the possibility to store in files be supported in new releases when also a Repository is available?

Will the possibility to store in files be supported in new releases we are not going to remove that run and use aspect of the tool.

Oracle sql developer Data Modeler -er diagram

Hi
I tried to Oracle sql developer data modeler for show relational ER diagrams.
Tables are came on data modeler but not shown relations between tables.
like this
How can show relations between tables?
http://i54.tinypic.com/30wxq1e.jpg

SDDM cannot create an ER diagram with only simple table definitions. It requires that primary keys (PKs) and foreign keys (FKs) be defined first. My guess is you imported these table designs from an existing database. If so, that database does not contain those constraints. (I have found this to be an issue in many organizations over the last 20 years - including my current job). You will have to determine:
1. The PKs for each table (either via data profiling or talk to someone who "knows" what they are supposed to be, or by reading application logic/code used to manage the tables).
2. The FKs between the tables. You may be able to guess some of that based on column names, otherwise you will have to figure them out (same as above)
Then you can update the model in SDDM with the PK definiions (manually). You must do that first before you draw in the FKs between the tables. Now if you want a true Entity Relationship model you need create a logical model from this relational model. The SDDM utility for that will convert the tables to entities and the FKs to relationships.
I have the basic steps with screen shots outlined in a presentation I gave in Denver in late 2009. It was an earlier version of SDDM but the basics are the same. You can find the presentation is here: http://www.rmoug.org/QEW2009/SQL%20Developer%20Data%20Modeler%20(2).pdf. Start at about slide 12.

SQL Developer Data Modeler: Logical model, unable to create arc

I have a logical model in SQL Developer Data Modeler. Entity A has two 'incoming' foreign key relations to entities B and C. Both releations have the same optionality and cardinality. I want to place both relations in an arc. I see the buttons in my toolbar menu, but they are not enabled. Even when I select both relations it is not.
Bringing the logical model to the relational model creates foreign keys. These foreign keys can be selected and when I do that the 'Create new arc' button in the relational model toolbar is enabled.
What am I missing in the logical model ...? The documentation doesn't give a clue.
Erik

Thanks Sue, that worked. It is different from the way the ERD in Designer worked. Is there any reasoning behind it. As far as I know you should only put into an arc two or more relationships pointing to the same entity with the same optionality and the same cardinality. Selecting the entity with the relationships can only help in identifying at which relationship end the arc should be created but that is obvious.
And asking the question is answering it: it will help in adding an arc to two or more entities originating and ending at the same entity (and same cardinality and optionality).
Is that the reasoning behind it?

Erik

Bug report SQL DEVELOPER DATA MODELER

Hello,
I think i found a bug using Sql developer data modeler 2.0.0 build 584.
When importing a DDL file to create a relational model, foreign key constraints might not be created if foreign key uses multiple-field and the fields are not referenced in the same order as the primary key was.
ex:
Table FOO ..... PRIMARY KEY (id_1, id_2)
FOREIGN KEY (id_2, id_1) REFERENCES FOO (id_2, id_1)
Benjamin
P.S: Bellow is a portion of SQL code demonstrating the problem:
-- "_decompte"
CREATE TABLE "_decompte"(
numero_rang VARCHAR2(2),
numero_contrat VARCHAR2(13),
id_decompte VARCHAR2(19)
ALTER TABLE "_decompte"
add CONSTRAINT pk_decompte PRIMARY KEY (numero_rang, numero_contrat, id_decompte);
-- "_decompte_detail"
CREATE TABLE "_decompte_detail"(
numero_rang VARCHAR2(2),
id_ligne NUMBER(4),
numero_contrat VARCHAR2(13),
id_decompte VARCHAR2(19)
-- "_decompte_detail"
-- NOT Recognized by SQL DEVELOPER DATA MODELER (fields are not in the same order as primary key definition)
ALTER TABLE "_decompte_detail"
add CONSTRAINT fk_decompte_detail_1 FOREIGN KEY (numero_contrat, numero_rang , id_decompte) REFERENCES "_decompte"(numero_contrat, numero_rang , id_decompte);
-- Recognized by SQL DEVELOPER DATA MODELER
ALTER TABLE "_decompte_detail"
add CONSTRAINT fk_decompte_detail_2 FOREIGN KEY (numero_rang, numero_contrat, id_decompte) REFERENCES "_decompte"(numero_rang, numero_contrat, id_decompte);

Hi,
Well, I was recently given some database scripts and asked to correct and improve them. These scripts were not generated but rather hand made. Having no access to a DBMS I was just curious about the result of this option in Data modeler and tried it for a better DB overview. I don't need it at all, but I was surprised to discover that the result was a failure. So I tried various scripts until I found the mistake.
regards.

MySQL functionality within Oracle SQL Developer Data Modeler

Hi all,
I've read a few forum posts here that lead me to believe that MySQL is not currently supported by the data modeler tool (Link #1 I got to by clicking on the Statement Of Direction link on the main page SQL Developer Data Modeler</title><meta name="Title" content="SQL Developer Data Modeler"&g… Link #2 I got to by doing a search on the word MySQL within the forum search):
Link 1:
SQL Developer Data Modeler Statement of Direction
Link 2:
Can datamodeler be used with MySQL?
SQL Developer (not the Data Modeler tool, but the database admin-type tool not for modeling) does support MySQL using the latest MySQL Connector J 5.1 driver but, strangely, it doesn't seem the Data Modeler supports it, though. Can anyone please confirm that MySQL is currently unsupported for the Data Modeler tool? Thanks in advance.

Hi,
it doesn't seem the Data Modeler supports it, though.
Data Modeler doesn't have specific support for MySQL - i.e you cannot generate DDL for MySQL. Though you can import form MySQL server using JDBC connection in standalone DM or using created MySQL connection if you are using DM inside SQL Developer.
You can import definitions for tables(columns, PK and UK constraints, indexes, foreign keys) and views.

Does SQL Developer Data Modeler fit-in??

Hi Everyone,
Wish you happy new year 2011.
Does SQL Developer Data Modeler support conceptual, logical and physical in our modeling or only logical and physical?
We all use Erwin for modeling. Erwin works without database repository storing models in desktop folders and provide additional reporting. I find some place SQL Developer Data Modeler talked about repository need.
Does SQL Developer Data Modeler store the models in local/network folders instead of Database server?
What are the functions need database based repository to work with SQL Developer Data Modeler?
We are thinking of using SQL Developer Data Modeler for our conceptual, Logical, and data dictionary need. Will it help in our need?
Do we need to face any surprises on using SQL Developer Data Modeler for our need?
Thanks in sharing your experience and helping me out.
RI

1) Do we need to have Oracle database at back end to work with SQL Developer Data Modeler?No, Data Modeler use Oracle database only if you create reporting repository.
Data Modeler is free, you need database license only if you want to log service request
2) Will SQL Developer Data Modeler create any tables (as backend repository ) in Oracle database to store Model details? no
3) Do we need to create reporting schema in backend oracle database to generate reports of SQL Developer Data Modeler's items such as Entity/attributes etc?no, reports can be created out of current loaded design. However having reporting repository will give you additional benefits - history (reports can be generated for every snapshot of your designs there) and multi-user usage, you can create your own reports
4) Do we to use SQL Developer Data Modeler reverse engineer from DB2, SqlServer, Terra data etc?Data Modeler has full support for Oracle, DB2/390, DB2/UDB(LUW) and MS SQL Server. Reverse engineering from other databases (including Terra Data) is at generic JDBC level - you'll get some and some will be missing (no check constraints for example).

Sql Developer Data Modeler 3.0 EA1: Custom transformation script

What is the object model used by:
Tools -> Design Rules -> Transformations
From looking at the examples (and guessing) I have managed to create ID attributes on all my entities, but how do I set its sequence number or set it as the primary key?
entities = model.getEntitySet().toArray();
for (var e = 0; e<entities.length; e++)
entity = entities[e];
att = entity.createAttribute();
att.setName('ID');
- Marc de Oliveira

content of XML files:
1) class described, parent class if there is one
2)<property .../>
describes property - set and get method, data type of property, default value
3) <collection ... />
describes collection of objects belonging to class - 5 collections are defined in Table.xml - columns, indexes, table check constraints, column groups and spatial definitions
- get method - to get collection
- create item method - method of described class used to create item for that collection; so for columns collection table.createColumn() will create column in table
- other methods - add, move, remove if are defined
4)other meta data
definitions in 1) .. 4) are used by Oracle SQL Developer Data Modeler, so it'll be wrong to modify those xml files
5)<roproperty ../>
Data Modeler doesn't parse/process these definitions, we decided to not filter them out however you should not rely that much on them
6)some junk left
For each object you can set your own properties and they will be persisted (also included in compare/merge in versioning) together with other information for object - look at "template table" example in transformation scripts. Here are methods you can use:
void setProperty(String key, String value);
     String getProperty(String key);
     boolean hasProperty(String key);
     boolean hasProperty(String key, String value);
     void removeProperty(String key);
     void clearProperties();
     Iterator getPropertyNames();

SQL Developer Data Modeler - integration with subversion

I just discovered the release of SQL Developer Data modeler, and found this to be very interesting.
We are still using Oracle Designer for database design, but we are looking for a replacement (for several reasons).
My question is quite simple:
Given that the modeler uses a filebased repository, and also given that we have several developers potentially working on a data-model at the same time, how does Data Modeler integrate with subversion for source control etc.?
Can the repository itself be under source control, and checked in/out directly from Data Modeler?
Or will only the output files be candidates for version/source control?
Let me admit right away that I have not read much of the data modeler docs, and I have also not downloaded/installed it (yet), but does anyone have pointers to docs on this , or general input/knowledge around it.
On a side note, I must say that it puzzles me that a company like Oracle, that delivers one of the best databases doesn't use its database engine to host the repository, but instead chooses to go for files (I assume xml) "scattered all over the place"....
Well, I guess they a have a reason for it..
Anyway:
Sql Developer Data Modeler and Subversion anyone?
Jens

Hi Jens,
It's early days and the initial implementation is indeed file based. Though I'd say not xml files "all over the place", but in ordered folders. Yes, as a database company it does make sense that we'd have a repository for managing and versioning metadata. However the tool supports Oracle and other databases and many companies use open source version control tools, such as Subversion and so anyone using the Data Modeler today can use it with Subversion regardless of the database they are designing for.
We do plan to have a repository, but in the 6+ months of the early adopter program found that many of the early adopters were happy to place the files under source code control using Subversion and in so doing also managed the multi-user development.
Integrated Subversion support is planned for a future release.

Oracle SQL Developer Data Modeler 3.0 Bugs, Resolution and workarounds

The purpose of this thread is to list bugs discovered while using ORACLE SQL Developer Data Modeler 3.0
Mainly with SQL SERVER 2005 and ORACLE 10g models.

SQL Server Physical model doesn't save table identity column.
here are the steps to get this bug:
1. create a table in relational model with a column as an integer to be used as an identity.
2. create or open a physical model for SQL-SERVER 2005
3. open the table in the physical model
4. edit the integer column property dialog
5. tick the identity check box and close the property dialog
6. save the model and close it
7. open it again, you will find the identity check is removed! (probably not saved from the start)

Customising the Legend (Legend Box) - SQL DEVELOPER DATA MODELER

Hi,
Is there a way to customize the legend Box (obtained when you right click Show->Legend in the Relational or Logical model window) in the latest latest version of SQL Developer Data Modeler.
For example i would like to remove a particular attribute from the legend say Changed by or Author.
Thanks in advance.

Hi,
It is not possible.
There will be such option in the future.

SQL Developer Data Modeler scripting

Hi,
I'm looking for a new modeling software for my company. SQL Developer Data Modeler (SDDM) has many features that fit my requirements. But there are some things that I'm not sure can be done. I work mostly with Oracle databases but still need to support some legacy and non-sql databases. Please look at problems below and tell me if and how those things can be achieved. Any suggestions for alternative solutions are welcome too.
1) I need to be able process Database Model from command line without human intervention and starting any GUI applications, for example generate DDL script form the model. Does SDDM have any interface for that?
2) I want to be able to export Database Model into a file in a custom (legacy) format.
3) SDDM stores database description in xml files. Is xml format defined anywhere? Are xsd schema files availabe?
4) Is there a SDK available that would allow reading SDDM Database Model into a custom application for further processing?
5) Is there any Java library available that parses Oracle-11-compatible SQL and PL/SQL?
Thank you in advance
Tomasz Grygo

Hi Kevin,
thanks for sharing your thoughts. There will be much more advanced find/search facilities in next version of Data Modeler and scripts also will be covered.
