A database can have objects with multiple owners. The script will give you the list of all the TABLES, VIEWS and PROCEDURES having the specified owner. Just input the owner name and it will give you the list of all the Objects with that owner. This scope of the script is limited to the TABLES, VIEW and PROCEDURES.
When doing bulk data changes it may be beneficial to disable indexes prior to starting the operation. Fortunately, SQL's rich metadata makes this very easy to automate in a robust fashion.
