Delta has been in the software development business for a long time and so is very familiar with the "similar but not exactly the same" problem. The very first Delta products in the 1970s directly addressed this problem with the Delta/ADS code generator product. Using the powerful generator techniques in Delta/ADS developers could separate application specific coding from the common code. The Delta/ADS macro technology allowed a certain amount of customizing of standard code for specific requirements.

Over the past 35 years Delta has continually refined and improved the core technologies used in the application development tools. The types of problems that are faced by large development teams are well understood – and it is exactly these types of problems that are addressed by generative programming.

Over the past 10 years Delta has carefully followed the research developments in the field of generative programming as these concepts exactly fit into Delta’s view of how software development can, and should, be done.
