Cornerstone is a relational database for MS-DOS released by Infocom, a company best known in the 1980s for developing interactive fiction video games. Initially hailed upon release in 1985 for its ease of use, a series of shortcomings and changes in the market kept Cornerstone from achieving success. It is considered a key factor in Infocom's demise.
