1. What is the difference between Page-Validate and Property-Validate methods? 

   Page-Validate method is used to validate all the properties present on a page. If a page has embedded pages, this method works recursively to validate all the properties. This method consumes lot of system resources and takes more time. If you want to validate specific properties use Obj-Validate method with Rule-Obj-Validate rule.  
   Property-Validate method is used to impose restrictions on a property value. Use Edit validate rule along with Property-Validate method to impose restrictions. You can validate multiple properties using Property-Validate method.

2. What is difference between Edit validate and Edit Input rules? 

   Edit Validate : Use edit validate rule to validate the property value using java code. Edit validate rules can be used property-validate, Rule-Obj-Validate and Property rules.
   Edit Input : Edit input rules converts user entered data into required format. For example is the user enters date MM/DD/YYYY format, edit input rule coverts this date into DD-MMM-YYYY (required format). Again we need to write java code for this transformation.

5. If I have 3 different work objects in my application, how to store them in three different tables?

   Open/Create the Data-Admin-DB-Table instance for each class and mention the table name. By doing this the individual work objects will be stored in the new table you mentioned in the Data-Admin-DB-Table instance. This is a best practice if there too many object instances for each class.
