Sql Developer Data Modeler 3.0 EA1: Preference- Naming standard- Templates

I am trying to figure out how the naming standard templates work.
When I go to:
Preference -> Naming standard -> Templates
It says that 'Attribute Relation' is '{ref entity} {ref attribute}'
What is the consequence of this?
I thought, it would mean that when creating a primary key attribute (ID) on an entity (DEPARTMENT), the related "foreign key" attribute (that is automatically created in related detail entities, such as EMPLOYEES) would be named DEPARTMENT ID.
Instead it is just called ID. Is that the intended behavior?

Marc,
you should check "FK Attribute name synchronization" setting in "Preferences>Data Modeler>Model>Logical model" - probably it's checked and you cannot change the name of FK attribute.
I found another bug here - FK attribute doesn't follow changes in referred entity - I logged it in bug database. As workaround you can apply defined templates at entity level (there is button in entity dialog) or for whole logical model (using pop-up menu in the browser).

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');

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 3.0 EA1: Auto route off

I admire that the data modeler tries to automatically position relationships and data flows. I am sure it is very hard to automate and I don't think it works very well in this tool.
So, I am happy that you have the option of turning "auto route" off as I am quite particular about how diagrams should look.
In the EA1 it seems that even with "auto route" turned of, all connected relationships and dataflows are automatically repositioned as soon as an entity or process box is resized or moved - even the tiniest bit.
I think the tool should not reposition relationships or dataflows as long as their current position can be maintained after the connected entity/process is resized or moved. When lines have to be moved the tool should try to maintain a position as close to its original position as possible.
Let me know if there is a way to achieve this.
Also, when relationships or dataflows have to be repositioned by the tool, I think they should be placed as far away from each other as possible (giving more room for labels). Currently, it seems that the default behavior is to lump relationships and dataflows close together when they connect the same entities or processes.
/ Marc de Oliveira

it's the same in Data modeler v. 2.0No, in version 2.0 it is not the same. The line stays in place if you move the entity or process in the same direction as the line, eg a vertical line is not repositioned if you move a connected entity or process vertically. The same goes for horizontal lines.
Also, when resizing the right side or the bottom side of an entity or process, lines connected to it are not repositioned (as long as the box does not become too small).
You can get lines "more" fixed if you introduce intermediate point Intermediate point? I never heard of that. Where do I learn more about that? I could not find it in the help file.

Sql Developer Data Modeler 3.0 EA1: Process order/number

When opening my version 2.0 model in version 3.0 EA1, the process numbers are as I originally saved them.
After saving the model as a version 3.0 model (using "Save as..."), when I reopen that version all processes have been reordered on all levels of my model (about 300 processes).
Actually, it looks like 1 becomes 4, 1.1 becomes 4.4, 1.1.1 becomes 4.4.4 etc...
Strange behavior. Is there any way to avoid this?

Hi Mark,
thanks for feedback. I logged bug for that.
Is there any way to avoid this?No for EA1 release.

Sql Developer Data Modeler 3.0 EA1: Relationship source and target names

When opening my version 2 model in version 3.0 EA1 the source name and target name of all my 231 relationships are deleted.
Is there a solution for this? I don't want to reenter these 462 labels...
Sincerely,
Marc de Oliveira

Hi Peter,
When I examine an XML file for a relation converted from version 2.0, the XML elements "nameOnSource" and "nameOnTarget" are missing in the converted 3.0 EA1 versionthey are not loaded during "open" of older design. If you define them they will go into XML file.

Sql Developer Data Modeler 3.0 EA1: Export - To reporting schema

When launching Export -> To reporting schema the schema tables are created and messages show that data is being generated but after indicating that it "Exporting Diagrams" I get the following error message:

and all the tables are left empty.
The message log is not indicating that anything went wrong.
What could be the problem?

Sql Developer Data Modeler 3.0 EA1: Engineering relationships to relational

When doing 'engineer to relational model' the relationship names are converted directly to foreign key names.
So, when the relationship between EMPLOYEE and DEPARTMENT is called 'working in' then the generated foreign key is also called 'working in' (not event 'working_in').
Is it possible to have it engineered to something like 'employee_working_in_department_fk'?
- Marc de Oliveira

Obviously, a property called "Plural" and an option for engineering using "Plural" names instead of entity names.
This would also allow us to have a nice relationship report where we could translate relationships into natural languages, like this:
Each DEPARTMENT may be employing one or more EMPLOYEES.

Domains usage in SQL Developer data MODELER

Hi,
I'm trying to understand how to use Domains in Oracle SQL Developer Data Modeler. We use version 3.1.3 . before I used Toad Modeler where domains are just part of your main design.
Oracle data modeler has some different concept.
let's assume I'm working on 2 designs: DesignA and DesignB that include relational models.
DesignA and Design B should use domains but list of domains in design A is very different than in design B.
Default domain file is located on c: drive where SqlModeler is installed. It is obviously unacceptable , so I need to change Default System Type directory in preferences.
And of course I want to have different domain directories for DESIGN A and DESIGN B.
So when I open design A then I changed Default System Type directory let's say to x:\AAA. Then i close design A and open Design B and change Default System Type directory to x:\BBB
I checked folders AAA and BBB and they have necessary XML files there: defaultdomains.xml, defaultRFDBSSites and so on....
Now questions:
can I rename defaultdomains.xls to something else like AAAdomains.xls? Domain administration can edit any domain file with any name , but how can I associate certain domain file with my design? My wish , when I open my design , then corresponding domain file will be open automatically. Is it possible?
If I open 2 designs in Sql Modeler and switch between designs then corresponding domain files should be changed automatically as well. Currently I shouldn't forget to change default System Type directory every time when I switch models. Is it the only way to handle it?
Thanks
vitaliy

Hi Vitaliy,
We use version 3.1.3
I recommend always to use the latest version. If you don't want to use beta (DM 4.0 EA is out) you can use DM 3.3.
Otherwise Oracle SQL Developer Data Modeler supports two types of domains:
1) DM installation domains - those in file defaultdomains.xml
2) Design level domains - they are stored in design directories and are visible to particular design only. They can be created in following ways:
2.1 Manually - there is a property "Domains file" and you id it's not set "defaultdomains" domain will become design level domain and will be stored in file with provided name (without .xml extension)
You can change later the file for design level domains, however you cannot change file for domain already in defaultdomains.xml.
2.2 Using types to domains wizard you can generate design level domains
2.3 Design level domains are created during import of DDL files (controlled in preferences)
2.4 You can import domains from specific file with domains using "File>Import>Domains" - you need to rename the source file if it's named defaultdomains.xml otherwise you'll get domains as installation domains
If the list with domains is too long you can define a list with preferred domains (or/and logical types) in "Preferences>Data Modeler>Model" and you can use shorter list in Table/Entity dialog if check "Preferred" check box next to "Type:" combo box.
If I open 2 designs in Sql Modeler and switch between designs then corresponding domain files should be changed automatically as well
If you open 2 designs in one instance of DM they will use the same file with default domains i.e. you'll lose domains in one of design depending of setting for "system data type directory". You need to go with design level domains.

Sql Developer Data Modeler all domains lost after changing to version 3.0

I have two questions:
1. Sql Developer Data Modeler - is it still a separate product? Or is it only available as integrated within Sql Developer?
2. After opening a model created with Data Modeler 2.0 with the new integrated Data Modeler 3.0 I lost all my domain definitions. What can I do to avoid this? Any help would be appreciated.
Thanks in advance
Holger

Hi Holger,
Sql Developer Data Modeler - is it still a separate product? Or is it only available as integrated within Sql Developer?Standalone version is here http://www.oracle.com/technetwork/developer-tools/datamodeler/overview/index.html
2. After opening a model created with Data Modeler 2.0 with the new integrated Data Modeler 3.0 I lost all my domain definitions. What can I do to avoid this? Any help would be appreciated.Copy file defaultdomains.xml from DM 2.0 installation to "sqldeveloper\sqldeveloper\extensions\oracle.datamodeler\types" directory (if you use version in SQL Developer) or to
"datamodeler\datamodeler\types" if you use standalone DM 3.0.
Location of this directory can be set in preferences - it's called system types directory there - it contains: default domains, RDBMS sites, logical types and custom scripts.

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
Raj

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.

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.

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
