SWire is a software interface enabling us to query Stata for the executing of basic operations like reading or writing data. The core of SWire is a Java plugin which functions as a server and it can be queried by using the HTTP protocol. SWire is in essence a wrapper around the Stata-Java API and all the functions relating to this API can, therefore, be externally called by clients.

Swire4R is an R package for exchanging data between R and Stata. SWire4R uses SWire for connecting R to Stata. SWire is a plugin for Stata >=13 which acts like a server: client applications can query SWire for interacting with Stata. SWire4R acts like a client application for Swire, providing the user with various basic functions for retrieving data from Stata and exporting data to Stata. SWire4R must be compiled by R.

Semantic query optimization (SQO) is the process of finding equivalent rewritings of an input query given constraints that hold in a database instance. We present a Chase & Backchase (C&B) algorithm strategy that generalizes and improves on well-known methods in the field. The implementation of our approach, the pegasus system, outperforms existing C&B systems an average by two orders of magnitude.
