A simple database language for personal computers has been implemented by selecting a subset of the ANS MUMPS language and enhancing it so as to meet the requirements of microcomputer end-users who are unfamiliar with computers. This database language is named Micro MUMPS. Its database is based on a modified prefix B-tree having parameters for adjusting its data organization according to the requirements of space and time efficiency. Experience with Micro MUMPS has demonstrated a remarkable reduction in programming time.

A simple interactive language named Micro MUMPS has been implemented on a microcomputer system. Its powerful facilities for data base manipulation and character handling make programming easy for end users who are unfamiliar with computers. Micro MUMPS is a practical subset of the language MUMPS which has been implemented on many minicomputers, and it also has some additional capabilities indispensable to micro‐computer applications. A modified prefix B‐tree is used in Micro MUMPS database and its organization can be changed according to the requirements of space and time efficiency.
