Abstract

A computer performed method for designing a system which allows multiple mainframe environments to be supported and managed within the overall system environment through the use of (1) one or more dictionary domains arranged in a hierarchy to model the mainframe environments and a target system release facility to move a process, system, subsystem or record and all its related records to another dictionary domain, and (2) a consolidated project data encyclopedia which is shared by all users and divided into 5 logical data bases and 1 access module, thus allowing access to projects in different stages of development on the same physical data bases. A migration facility allows the user to manage the orderly progression of entities through the development life cycle by moving entities between logical data bases.

Claims

1. A method in a computer system for managing a plurality of data records stored in a data base on said computer system, which data records are used by a plurality of users and processes operating in said computer system, wherein a migration of certain modified said data records between two areas of said data base is performed, said method comprising the steps of:

creating a plurality of dictionaries, each of which identifies a set of logically related ones of said data records;

assigning said plurality of dictionaries in hierarchical order into at least two logical data bases within said data base, each said logical data base being accessible by said users and processes operating in said computer system; and

defining an encyclopedia that contains data that specifies a set of relationships between said plurality of dictionaries and said at least two logical data bases to regulate said migration of modifications to said data records between said plurality of data dictionaries within each of said at least two logical data bases.

2. The method recited in claim 1 wherein said encyclopedia specified relationships allow any said user or said processes to be related to one or more other of said processes.

3. The method recited in claim 2 further comprising the steps of:

assigning each of said users and processes a unique key to identify that user and process;

permuting a key assigned to one of said users or processes to define relationships with an other of said users or processes;

storing said permuted key in said encyclopedia.

4. The method recited in claim 1 wherein said ordered hierarchy of dictionaries comprises an ordering of at least two dictionaries such that each lower level dictionary in said ordered hierarchy inherits the contents of the higher level dictionaries in said ordered hierarchy.

5. The method recited in claim 4 wherein changes made within data records identified by a dictionary or within a dictionary itself affect only that dictionary and its subordinates in said ordered hierarchy.

6. The method recited in claim 1 wherein said step of assigning includes one of said users defining an arbitrary hierarchy of said dictionaries to control changes to the ones of said data records identified by said dictionaries.
