Alpha Database

A database program originally introduced in 1982 for DOS, initially a flat-file database that was marketed as an easy to use budget alternative to relational systems, but with the advent of the relational Alpha Four in 1986 the marketing started leaning towards describing the system as an easy-to-use menu driven alternative to difficult to learn programmable relational databases The company continued to sell Alpha Four alongside the flat-file Alpha three for some time after the introduction of Alpha Four.
