| Guidelines |
| The SQL language is the dominant interface for querying relational databases. However, as a programming language, SQL has a number of limitations. The langauge often relies on ad-hoc extensions and queries cannot generally be constructed in a compositional way (building more complex queries from smaller parts). The aim of this thesis is to design a novel query language for relational databases and implement a support for the language in PostgreSQL [4]. The language will offer a more uniform and composable model for constructing queries based on two primitive notions, filters and functions.
The language design can draw on existing composable query systems such as LINQ, XQuery [5] and Pig latin [1]. It can be implemented as a PostgreSQL [4] extension that translates the input to an appropriate PostgreSQL query representation, by mapping the (compositional) input query to a corresponding (more ad-hoc) SQL-like representation, using translation techniques such as [2, 3]. The work should result in a langauge impementation with a number of case studies that illustrate its compositionality and uniformity, as well as a rigorous (either formal or informal) description of the langauge and interesting aspects of the translation procedure. |
