[ What is claimed is:] [1.]1. A method of storing data in a database stored on a data storage device connected to a plurality of computers, the method comprising the steps of:allocating at least one look-aside space map to each system of a multi-system data sharing environment, wherein the look-aside space map identifies data pages associated with a corresponding system; andat each system of the multi-system data sharing environment, when data is to be inserted into the database,searching for a look-aside space map with one or more free data pages allocated to that system;when a look-aside space map with one or more free data pages is identified, inserting data into the data pages referenced by the identified look-aside space map, wherein the insertion of data into each system is isolated from the insertion of data in each of the other systems; andwhen a look-aside space map with one or more free data pages is not found, dynamically allocating one or more additional space maps to that system.
