==History==

DAL started as a 3rd-party product, '''CL/1''' (''Connectivity Language One''), from a small vendor, Network Innovations. Apple purchased the company in 1988,<ref>[httphttps://books.google.cacom/books?id=jspVAAAAMAA "Apple Acquires Network Innovations"], ''Wheels for the Mind'', Boston College, 1988</ref> during a 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.

DAL suffered from most Apple problems of the early 1990s, notably an alternating level of support in which Apple would aggressively promote the product and then ignore it. Throughout, the company struggled with promoting the system as a cross-platform standard, or as a Mac-only technology.<ref>Jeff Moad, [httphttps://books.google.cacom/books?id=uRlJAQAAIAAJ "Apple Says Yes to SQL"], ''Datamation'', 1990</ref> DAL's release was also coincident with Apple's fall from grace in the business world, and not coincidentally with [[Microsoft]]'s [[ODBC]] efforts.

DAL appears to have seen little use, and eventually Apple sold it to Independence Technologies in 1994, during a sell-off of a number of "high-end" packages such as their [[X.400]] server and an [[Systems Network Architecture|SNA]] client.<ref>[http://www.xcbronline.com/news/apple_divests_data_access_language_snaps_takes_bedrock "Apple Divests Data Access Language, SNAps, take Bedrock"], ''Computer Business Review'', 26 January 1994</ref> Independence Technologies was a [[middleware]] vendor, better known as a major reseller of the [[Tuxedo (software)|Tuxedo]] product for [[Unix]]. In 1995 [[BEA Systems]] bought the company, and in turn sold it to [[UniPrise Systems]] in late 1996. No releases took place during this period.
