Solution
-
Regulate the application behavior: This concept is related to the management of how an application operates. It involves setting rules or guidelines for the application to follow in its operations. This could be related to how the application handles data, how it interacts with the user, or how it performs its tasks.
-
Express basic semantic properties inherent to a model: This concept is related to the representation of data in a model. It involves defining the basic properties or characteristics of the data that are inherent to the model. This could be related to the type of data, the relationships between data elements, or the rules that govern the data.
-
Break down a calculus query into an algebraic query on global relations: This concept is related to the process of simplifying a complex query into a simpler form. It involves breaking down a calculus-based query, which may involve complex mathematical operations, into an algebraic query that operates on global relations. This could be related to the process of query optimization or query rewriting.
-
Transforms the distributed query into a query on fragments: This concept is related to the process of modifying a query that operates on a distributed database into a query that operates on individual fragments of the database. This could be related to the process of query decomposition or query distribution.
-
Finding the best execution strategy for the query: This concept is related to the process of determining the most efficient way
