Using Host Integrator tables enables you to create a database abstraction of your host application so that client applications can query it using a subset of the industry standard Structure Query Language (SQL). Table columns are usually associated with attributes and fields in the Host Integrator model. This makes it possible for you to access the data in your host applications via SQL queries even if your host application is not designed to respond to SQL queries. Host Integrator tables themselves don't contain data; rather they provide a database-like view of the underlying host data.
In a query statement, the client application specifies a table, a set of input parameters, and a set of desired output parameters in the form of an SQL statement. From this statement Host Integrator determines the appropriate procedure or procedures to run in order to return the desired results.
Host Integrator accomplishes this through the use of tables and procedures. Using the Tables dialog box, you can create one or more tables for a host application. Each table can have one or more associated procedures. The procedures are comprised of entity navigation paths and parameter mappings that tell Host Integrator how to read, write, and modify host data represented by the table.
Use the Table Wizard or the Tables dialog box to create a database abstraction of the Host Integrator model.
When you export the documentation for your host application model, a list of all table and procedure names is generated. Use this list to access the tables and procedures from one of the Host Integrator APIs.
