Informix® Warehouse Accelerator
These topics include information about installing and configuring the accelerator server, creating data marts, accelerators, and accelerated query tables (AQTs).
The first step in creating a relational database is to construct a data model, which is a precise, complete definition of the data you want to store. After you prepare your data model, you must implement it as a database and tables. To implement your data model, you first select a data type for each column and then you create a database and tables and populate the tables with data. You can also implement fragmentation strategies and control access to your data.
