HI ,

Performance Tuning..

1. Check the SELECT STatements

a. Specify necessary conditions to retrieve the data

b. Specify all the key fields if known.

c. Make sure that the tables are not empty when used

in SELECT --- FOR ALL ENTRIES.

d. Always clear/ refresh variables and tables if not

required any more in the program.

e. Use the INTO TABLE instead of INTO CORRESPONDING

FIELDS OF TABLE in a SELECT statement.

2. Check the Nested Loops in the programs.

3. Avoid SELECT inside LOOPS.

Instead of using SELECT inside loops...use the

appropriate JOINS to select records from two or more

tables.

4. When using the CONTROLS, optimally use the FLUSH

Commands.

5. Read the tables by Binary Search Method specifying

the Keys used for Sorting that table.

6. Use of right kind of Internal tables (Standard,

Sorted, and Hash tabes) is very important.

Integration Testing.

It is always good practise test the individual applications thoroughly before going for integration testing. The application accessing all the submodules is tested only when the individual components are working correctly.

Unit Testing.

1. Initially check the coding standards specified by

your company/ client.

2. Check the performance tuning techniques specified in

above.

3. Check the application specific conditions.

4. Check for all the errors and the corresponding error

handling conitions.

5. Do the negative testing, that enter incorrect data

to process records.
