A query language for information graphs
This thesis describes the Graph Object Access Language (GOAL) and optimization techniques to execute GOAL statements. GOAL can be used to retrieve information stored in an object-oriented database system modeled as an information graph. It is an extension of the LEND query language developed by …

GTQL : a query language for game tree
… In this thesis we introduce the Game Tree Query Language (GTQL), a query language specifically designed for game trees. The language can express queries about complex game-tree structures, including hierarchical relationships and aggregated attributes over subtree data. We also discuss the …

An interpreter for object comprehension query language
Object Comprehensions are a new query notation introduced in 1994 by Chan and Trinder to provide a declarative query language for object-oriented databases. Object Comprehensions allow queries to be expressed clearly, concisely, and processed efficiently, while incorporating many features that are …

A database query language for operations on historical data
… is defined.<br/><br/>Finally the Historical Query Language (HQL) is defined and implemented. HQL is designed to allow users to interrogate the historical database in a natural way without referring to the time domain explicitly. HQL has a user friendly syntax and supports user-defined …

A database query language for operations on graphical objects
… is argued that graphical database query languages should be designed to be application specific and the user should be protected from the relational algebra which is the basis of the database operations. Such a base language (an extended version of DEAL) is presented which is …

Towards A Sufficient Set of Mutation Operators for Structured Query Language (SQL)
Test suites for database applications depend on adequate test data and real-world test faults for success. An automated tool is available that quantifies test data coverage for database queries written in SQL. An automated tool is also available that mimics real-world faults by mutating SQL, …

Towards a concurrent implementation of keyword search over relational databases.
… stored in relational databases. Traditionally, querying this data required a deep understanding of the underlying schema in addition to knowledge of a query language such as structured query language (SQL). We present a framework for the automatic, lossless transformation of data from the …
