Array Technology is a provider of technology for solving complex constraint problems in real-time - on a very small memory footprint. The technology is used in a range of business applications, e.g. for product configuration with a lot of business rules or constraints. The key to the performance of the technology is the use of nested arrays (array-based logic) for handling logical constraints with a multitude of combinations. Dyalog 8.2 was used for prototyping of the first version of the technology, but Gert will present how the next generation of the technology may benefit from the power of the latest Dyalog releases.
