HOWTO

What do I need to decide?

In order to create an EMdF schema, you have to decide:

• What the name of the database should be.
• Which object types to create.
• Which features to create.
• Which enumerations to create.

How do I write the schema file?

First, you write the following commands:

CREATE DATABASE your-database-name-here
GO

USE DATABASE same-database-name-here
GO

This sets up the database and connects to it.

Then, you write MQL statements to create:

1. the enumerations first,
2. then the object types.

This is because the enumerations need to be defined before they can be used for feature types in the object types.
