This project proposes a new approach to interact with database systems through programming languages. A formal query language can be integrated within modern programming languages and the semi-structured queries can be evaluated using automatic transformation and query shipping. The focus of this project is on XML queries and Scala programming language. Particularly, this project optimizes the XML-based expressions of Scala using XQuery transformation and Shipping. In this work, Scala sequence comprehensions are extended to cover appropriately the whole functionalities of XQuery FLWOR expressions and XQuery sequence comparisons are introduced in Scala to facilitate query generation. This report presents a formalization of transformation rules between Scala and XQuery languages and describes an Scala implementation. Various use cases are provided to facilitate understanding and employing this newest Scala library.
