An object-oriented framework provides an interface for use with object oriented data management systems to provide multiple types of object-oriented data access to record-oriented data files, and can utilize multiple record file adapters to provide OOP applications with access to multiple types of record-oriented data files. The framework thereby permits API programmers to easily create OOP applications that manipulate data in record file data storage. Thus, the framework accesses data stored in record file data structures through a dual two-way interface with persistent object data management services.

[ I claim:] [1.] A method of operating a computer system that provides an object-oriented programming environment, having one or more datastores that contain record-oriented data files, and communicating with one or more users executing object-oriented application programs for manipulation of persistent data objects corresponding to the data files, the method comprising the steps of:(a) receiving a request for manipulation of a persistent data object from one of at least two incompatible persistent object service systems utilizing different data protocols and class hierarchies;(b) associating each persistent data object with a data file by(1) associating each instance of a persistent data object with a persistent object identifier;(2) associating each instance of the persistent data object with only one data file in a datastore, such that each instance of an attribute of the data object is mapped to one associated data file, and(3) defining within each persistent object identifier a data identifier that is associated with either a record number or a key within the data file associated with the persistent object identifier; and(c) instructing the datastore to alter the information within a selected data file through the associated instance of the persistent data object.
