Xbase language interface to the Emerald Bay database system. Vulcan
consists of the Vulcan Interpreter, EXE Compiler and Linker, Emerald
Bay Database Engine, Database Repair Program, Database Log Replay
Program, 2-User Database Server, Database Administrator, Screen
Painter, Rosetta import/export, Report Writer, External Routine
Libraries, and Sample Programs. The TSR Database Engine manages data
and index files, automatically opening and updating indexes as records
are added, changed and deleted. Databases consists of two disk files
including a data file and an index file. Stores up to 1,000 indexes
in each index file. DBF files become tables, and the user can open
seven databases simultaneously, providing access to up to 7,000
tables. The Data Dictionary describes the structure of each table and
field in a database. Variable length data fields enable a smaller
database than traditional DBF files. Datatypes include character,
Boolean, integer, binary coded decimal, real, date and time. A
special binary datatype lets the user store documents, programs and
images of any size. Field arrays support fields of up to 100
elements. Security information stored in the database tells the
program what data each user is allowed to access, and how the users
are allowed to use the data, such as read-only, write, add and delete.
Uses a combination of username and password to control access. The
DBA program is a tool for creating databases, defining tables and
fields, creating indexes, and setting user security.ÒÅÐÌÈÍÛ
