Basically SAP has created some logical Data base.

For ex. If you want to see the Open AR report for Customer there is a LDB for that.

Go to SE36, LDB - DDF and look for the structure and the source code. You can use this LDW in the program that you create. Look in attributes for the program created in SE38. You will find option for the LDB.

For the above example LDB - DDF, only with the statement GET BSID, you will get all the information releated to the customer.

God and easy to use but might be some performance issues.
