Helping Developers Find Useful Tools
PLATO Lecture Series Spring, 2014 – Greeners on the Cutting Edge

The path from a large collection of passive data to actionable intelligence in the enterprise software environment is fraught with an astonishing degree of unnecessary complexity. At LogicBlox, we have been addressing this problem by designing a single software platform that combines traditional database capabilities (transactions, parallelization, distribution, durability) with analytics (optimization, machine learning) unified by a single declarative language (based on Datalog).
In this talk, we show how a whole class of mathematical optimization techniques (mixed integer programming) can be tightly integrated with a database. This abstracts away the complexity of data management, transformation and inter-operation with complex software artifacts (mathematical programming solvers), while allowing the programmer to specify large-scale optimization models at the domain-appropriate level of abstraction. The result is a “smart database” whose “tables” can store not just values, but numerical values that are optimal with respect to some objective function and obey a set of numerical constraints.
We present an example based on a real world application of optimizing supply chain for a large retailer.
Emir Pasalic is a computer scientist at LogicBlox, Atlanta GA. Emir’s interests include multi-stage programming, type theory and domain specific languages.designs; currently, he implements database platform support for mathematical programming, optimization and in-database machine learning. As a postdoc at Rice, he worked on adding dependent types to OCaml by plugging Coq into its type checker and on program generation (e.g., staging dynamic programming algorithms) at the Rice PLT group.

For each domain, they highlight language extensions, runtime considerations, and use cases. They also briefly survey other applications.
