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.
