Abstract
Indexes for predefined search orders of items in a database are generated and stored. When a client issues a database query a responsive pre-generated index list is retrieved and provided to the client for use in, e.g., populating a U/I view for a user. Only those items that a client needs, e.g., for populating a current U/I view, are retrieved from the database and output to the client. When a change is rendered to the database, e.g., an item is added or deleted or an existing item is altered, only the change is output to the client, rather than the entire modified index or altered item. In this manner clients can more quickly and efficiently respond to user data query requests by performing some processing upfront and by limiting communications traffic to communications relevant to the client's current processing.
