The article discusses the importance of queries in databases and how they can be complex in relational databases. The researchers introduce a schema for optimizing dynamic queries and modifying them using mathematical function-oriented techniques. They propose a new query language called Dynamic Dimensional Query Language (DDQL) that works with object-oriented database systems. This language allows users to retrieve, update, and delete dimensional and multidimensional information about objects based on their dimensional locations. The researchers also present a two-level data modeling method for designing and implementing application-based query languages.
