The DB2 Development Center is a powerful IDE for developing stored procedures in all DB2 platforms. For DB2 LUW, user-defined functions can also be developed. By defining multiple projects (which may share the same database), you can manage related database application objects with ease. The integrated debugger allows you to debug complex SQL procedures, even if they make nested procedure calls. Debugging concepts and strategies were highlighted, and more help on the Development Center is available from the documentation provided with the product.
