Role of Schema & Occurence of Error 211
Schema is a logically grouped SQL Objects such as tables, view stored procedure and other associated elements. When schema is generated one can access the database in more restricted manner.
Suppose we need to create a schema for one user, then access to the database will be in such a manner that the user will be able to use only those specific area where privileges has been assigned to him. This is generally done to narrow down the database to cater only specific requirement.
