High Quality Content by WIKIPEDIA articles! R:BASE (or RBASE) was the first relational database program for the PC. Created by Wayne Erickson in 1981, the original R:Base database was written on a Heathkit CPM computer that Erickson built at home. On November 13, 1981, Erickson and his brother, Ron Erickson, incorporated the company, MicroRim, Inc. to sell the database. MicroRIM. (the RIM was an acronym for Relational Information Management,a mainframe database developed at Boeing Computer Service by Erickson and used by NASA to track the heat shield tiles on its space shuttles.) Privately funded and ultimately venture backed, the MicroRim database products achieved significant market share in the mid-1980`s in what was dubbed by some, the "database wars" between R:Base and the market share leader, Ashton-Tate`s D-Base. One clever MicroRim ad stated "R-way versus D-hardway," a jab at the inferior D-Base architecture. MicroRim adhered to the rules of the father of relational database technology, Edgar F. Codd and prided itself on the elegance of its code.
