Abstract

The system and apparatus for loading and retrieving information relates to a computer-implemented database management system for multiple source databases. The system also has a variety of database management tools. The system uses hierarchical, network, and relational structures to establish and maintain relationships between disparate categories of information in multiple records or databases within the system. Data entered into the system are stored in a common data repository in disk memory, which categorizes each source field independent from the source record definition. Separating the source record definition from the fields within each source record definition allows data to remain independent from the original structure of the information. Yet, source record definitions are maintained to show the relationships between data from different fields. The system allows all data to be referenced by any number of methods without regard to how the data was entered into the system. The system also allows any data modeling record (DMR) in the system to act as a menu, filter, or gateway to other DMRs or applications and to provide a data security system which gives a database manager sophisticated control of access to all DMRs and applications within the system. The system also provides for continuous modification of the database without any system down-time.

Claims

1. A computer storage device for storing a data modeling record comprising:

a root block stored in the computer storage device, wherein the root block has a Chain-1 data array for containing data look-up references; and

a Chain-2 data array stored in the computer storage device for containing two-way network linkages.

2. A device according to claim 1 further comprising:

a non-root block stored in the computer storage device, wherein the non-root block has a Chain-1 data array for containing data look-up references.

3. A device according to claim 1 further comprising:

a Chain-4 data array stored in the computer storage device for containing instructions regarding data access.

4. A memory for storing data for access by an application program comprising:

a database management record data structure stored in the memory including;

a root block stored in the memory, the root block containing a first data array with look-up references to data stored in a common data repository; and

a second data array stored in the memory, the second data array containing two-way pointers to other database management record data structures.

5. A memory for storing data for access by an application program according to claim 4 comprising:

a third data array stored in the memory, the third data array containing additional look-up references to data stored in a common data repository.

6. A memory for storing data for access by an application program according to claim 4 comprising:

a fourth data array stored in the memory, the fourth data array containing instructions regarding data access.
