Explain The Following Terms: Regeneration, Optimization & Pbd?

1.	Explain The Following Terms: Regeneration, Optimization & Pbd?
Answer» Regeneration – when you modify an ancestor OBJECT, you can regenerate descendants so they pick up the code changes to the ancestor. Optimisation – it is the process of compressing library objects; it removes gaps in libraries and defragments the storage of objects, thus IMPROVING performance. Optimising only affects the layout on disk and not the contents of the objects. Objects are not recompiled. For best performance libraries should be optimised once a week. PBD – DW objects are stored in PBLs that are CONVERTED to PBDs THEREBY providing runtime versions of DW objects.
