ABSTRACT:
A Client/Server Database System with improved methods for appending items to an object, such as appending data records to a database table, in the context of a multi-user environment is described. The system includes one or more Clients (e.g., Terminals or PCs) connected via a Network to a Server. The Clients store data in and retrieve data from one or more database tables resident on the Server by submitting SQL commands, some of which specify insert or append operations, for appending records to a table. For enhancing the speed in which multiple appenders (i.e., Clients) can append records, the operation of the server is modified to store an object (e.g., table) as multiple (physical) page chains. From the logical viewpoint, a single (logical) page chain of data pages is presented to each client or user. From the perspective of inserting records, however, the system has multiple page chains to insert into, thereby removing contention among multiple appenders for the last page.
