This chapter contains the following topics:
Use these guidelines when you create table I/O functionality.
Ensure that you:
Update the date,time,user, and program name when updating a table.
Create a business function for each table to provide an API to retrieve, insert, delete, and update data from the table.
For simple retrievals, insertions, deletions, and updates, use table I/O statements in Event Rules Design.
Avoid updating a table with a business function from a different vertical than the vertical for the table.
If a business function accesses multiple tables, limit the table I/O or API to the tables within same vertical as the business function. Ensure that a business function calls additional functions to retrieve data from other verticals.
