Universal Query Language.
Piotr Wiśniewski, Krzysztof Stencel · CS&P · 2012
In the prequel paper we introduced the Uni ed State Model (USM), i.e. a single model that allowed conveying objects of popular programming languages and databases. That model exploited and emphasized common properties of all these objects. We showed mappings between those popular data models and USM. Our natural next research goal is the Uni ed Query Language (UQL). UQL is intended to be a minimalistic and elegant query language that allows expressing queries of major query languages. We plan to build a concise set of operators and show its coverage for mentioned languages' constructs. In this paper we present our initial e orts towards UQL. We present a set of language operators. We also provide a number of redolent examples of queries expressed in UQL.
