Introduction

One of the ingredients in all Enterprise Objects Framework applications is a model. A model defines, in entity-relationship terms, the mapping between your enterprise objects and a relational database. The EOModeler application, being the tool you use to create and maintain models, has a prominent place in the suite of applications you use to develop your Enterprise Objects Framework applications.

You use EOModeler to:

• Read the data dictionary from a database to create a default model, which can then be tailored to suit the needs of your application.

• Specify enterprise object classes for the entities in your model.

• Generate source code files for the enterprise object classes you specify.

• Define fetch specifications (queries) that you can invoke by name in your applications.

• Create and drop databases and database tables.

For more general information on Enterprise Objects Framework and on creating applications that use it, see the book Enterprise Objects Framework Developer's Guide.
