Data Access Language (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Data Access Language, or simply DAL, was a SQL-like language parser released by Apple Computer in 1990 to provide unified client/server access to database management systems. It was known for poor performance and high costs, something Apple did little to address over its short lifetime at Apple. DAL was later sold off in the early 1990s. DAL is used as the native SQL dialect of the PrimeBase SQL server, as well as the now-defunct Butler SQL. DAL started as a 3rd party product, CL/1, from a small vendor, Network Innovations. Apple purchased the company in 1988, about the time that client/server databases were becoming a hot issue in the industry. They released their first version of the re-branded software in 1989, for MVS, and followed with other versions over the next year or so.
