Use the Administration Console option on your Adaptive Server to create or modify tables and table objects.
Tables consist of columns and rows that contain data on a database.
Adaptive Server uses the following types  of tables:
- A system table stores information that allows the database to perform
its services.
 
- A user table stores and provides access to user data.
 
- A proxy table accesses data on remote servers.
 
 
Note: System table definitions are not usually updated.
To plan the table's design:
- Decide what columns you need in the table, and the datatype, length, precision, and scale, for each. 
 
- Create any new user-defined datatypes before you define the table where they are to be used. 
 
- Decide which column, if any, should be the IDENTITY column.
 
- Decide which columns should and which should not accept null values.
 
-  
Decide what integrity constraints or column defaults, if any, you need to add to the columns in the table. 
 
- Decide whether you need defaults and rules, and if so, where and what kind. 
 
- Consider the relationship between the NULL and NOT NULL status of a column and defaults and rules. 
 
- Decide what kind of indexes you need and where.
