BDMS: Berkeley data-base management system user's manual (version 1. 2)
BDMS is a general-purpose data-base management and information retrieval system with a broad range of capabilities for creating, maintaining, and accessing computer data bases. It frees programer and end user alike from concern with the physical storage of data, making it possible instead to deal with data at a logical level; in other words, it allows one to deal with information rather than data. Many applications that previously would have required extensive special program development can be handled by the system with little, if any, extra software. Its capabilities include a natural and easy-to-use data-base definition language; a powerful editor that operates directly on the data base; extensive retrieval facilities including controlled data-base inversion, Boolean and relational operators, nested parentheses in search expressions, truncation and range searching, and saving and reuse by name of intermediate search results; a standard listing format that makes the structure of the data readily apparent; a common command and data language for both batch and interactive use; and exits to user-supplied routines at several places in the system to allow for special I/O processing, data validation, and the construction of data element and key values.
