IBM certified Application Developer – DB2 9.7 certification is concentrated on people who are experienced in developing applications that support database. The developers who develop should be able to create, design and maintain the application that uses the DB2 as technology. They must know development of applications that are new and also should know how to change or convert the exiting one according to the new specifications. Applications thus developed should be highly reliable and consistent such that there must not be any security threat and achieve high performance. Also, the developer must also know the administration concepts which might help developing a robust application. By passing this certification, a developer would become competent in application development that supports IBM DB2 9.7.
Who can do this certification

So the first step towards IBM certified Application Developer – DB2 9.7 certification is to pass either one of these exams.
Second and the final step is to clear the exam C2090-543 - DB2 9.7 Application Development which would earn you and IBM Certified professional award in application development.
There is a defined knowledge level required for attempting any certification. However, it would not be a mandatory one. There are certain courses recommended to be done before taking up this certification. Those courses cover the concepts of programming with WINDOWS, LINUX and UNIX and also cover the knowledge pertaining to the advanced concepts of application programming procedures in DB2 for LUW. Every individual has the sole responsibility to take up each certification with a high level of knowledge in the subject. Any clarifications one the requirements for eligibility could be known from the website and thus taking the primary step towards attempting to clear the certification.
This exam mainly covers the below topics such as
- Objects of the database like table, alias and views
- Using the SQL functions and procedures and the in-built routines of DB2
- Datatypes of DB2 (LOB, Date, Time, Integer, Strings etc)
- Manipulating the data traditionally by knowing what is static and dynamic SQL.
- What are cursors and the different types of cursors?
- Creation and manipulation of Cursors and their scope.
