DISTRIBUTED DATABASE MANAGEMENT SYSTEM
First Claim
1. A system comprising:
- a database system configured to store a central database comprising database objects;
one or more server-side computing devices communicatively coupled to the database system and configured to;
access the central database;
divide the central database into slices, each of the slices comprising at least a portion of one or more of the database objects; and
transmit individual slices of the slices from the one or more server-side computing devices to client-side computing devices;
said client-side computing devices, communicatively coupled to the one or more server-side computing devices via one or more networks, the client-side computing devices configured to;
receive a set of the slices from the one or more server-side computing devices;
generate local databases of objects from the central database based on set of slices received by the client

Abstract
A distributed database management system provides a central database resident on a server that contains database objects. Objects, e.g., program guide data, to be replicated are gathered together into distribution packages called “slices,” that are transmitted to client devices. A slice is a subset of the central database which is relevant to clients within a specific domain, such as a geographic region, or under the footprint of a satellite transmitter. The viewer selects television programs and Web content from displayed sections of the program guide data which are recorded to a storage device. The program guide data are used to determine when to start and end recordings. Client devices periodically connect to the server using a phone line and upload information of interest which is combined with information uploaded from other client devices for statistical, operational, or viewing models.
