Determining How Often Transactions Will Be Executed

Early in the design process, you need to determine how often each transaction will be executed. This can give you an indication of how the transaction might affect the overall performance of the system.

To determine how often particular transactions will be executed:

• Find out the hours when each transaction will be run.
• Create a preliminary schedule of batch update and reporting program runs.
• Once you have created a schedule of processing jobs, estimate how often each transaction will be executed during the hours when it is typically run.

Sample transactions

The following table shows how often three typical transactions will be executed.
