The official way to share the global configuration between computers is to use the various import and export utilities from the Data Modeler. Oracle SQL Developer Data Modeler has several global configuration items like:īesides that there are also design preferences and glossaries but you can store them in a version control system easily unlike the global configuration. You can better use one modeling project for all your applications when you use SQL Data Modeler so you can share your configuration more easily between projects and developers.įrom my GitHub datamodeler project here the README:Ī project to share Oracle SQL Datamodeler settings and scripts. Var tables = model.getTableSet().toArray() This custom utility ( Table Names Plural - custom) allows you to do it automatically: You usually define the entity name in singular and the table name in plural. Here an example for setting the table name to plural. This allows you to use predefined scripts to do transformations and to define your own.

Applicable for both the Logical Model and Relational Models. This is the lint like tool of Data Modeler, an analysis tool that flags errors, bugs, stylistic errors and suspicious constructs. One of the features I can really recommend are the Design Rules And Transformations: Design Rules Sometimes you may need to tweak the generated script. This will create an incremental migration script you can use with Flyway. Then you can use that connection to execute the Synchronize Data Dictionary functionality. You can define a connection via: Import Data Dictionary menu option Maybe I did it wrong, maybe the database version (Oracle Database 12) was a little buggy or maybe it works just nice in theory. I have had difficulties with constraints implemented by materialized views with refresh fast on commit in an APEX environment. For more inspiration I will refer to implementing business rules by Rob van Wijk. Other constraints may not fit into Data Modeler and may need to be implemented in another way.

Quite a few business rules can be defined easily using Data Modeler, here some examples: business ruleĮmployee job must be ‘CLERK’, ‘SALES REP’ or ‘MANAGER’.Įmployee salary must be a multiple of 1000.ĭomain (which lets you define a constraint)Įmployee exit date must be later than hire date. I am old enough to remember the Business Rules Classification: Business Rules Classification This is the foundation of your application. My preference is to just one relational model per Logical Model to keep it simple.Īgain you should really take your time to design your relational model and to verify it using the Design Rules described later on. This allows you to use the features of those versions. Relational ModelsĮach Logical Model may be transformed into a Relation Model, one for Oracle Database 12c, Oracle Database 12cR2 and so on. You can even have one corporate domains XML file if you prefer. This is the foundation of your application.Īnd do not forget to use domains whenever appropriate. You should really take your time to design your model and to verify it using the Design Rules described later on. This is the Entity Relationship Model area where you can construct Entity Relationship Diagrams (ERD) like this: Logical Model A simple SQL script to create the view is just enough. This utility allows you to define views but I do not use it since it gave me a lot of problems. For other activities I use tools that suit me better, the Unix approach. I use Data Modeler mainly for modeling, documentation and generating DDL scripts for the initial setup and incremental migration scripts later on. Oracle SQL Developer Data ModelerĪ book I can recommend is Oracle SQL Developer Data Modeler for Database Design Mastery by Heli Helskyaho. This time I will discuss Oracle SQL Developer Data Modeler. Last time in “How to build an Oracle Database application (that supports APEX, Java, React or any other front-end) (3)”, I told you about the Oracle Database and Oracle APEX.
