Evaluating student achievement with a relational database

Evaluating Join Performance on Relational Database Systems

The join operator is fundamental in relational database systems. Evaluating join queries on large tables is challenging because records need to be efficiently matched based on a given key. In this work, we analyze join queries in SQL with large tables in which a foreign key may be null, invalid or valid, given a referential integrity constraint. We conduct an extensive join performance evaluati...

Storing and Evaluating Horn-Clause Rules in a Relational Database

This paper describes a practical approach to storing and evaluating Horn-clause rules in a relational database system. The intention is to give a complete outline of what needs to be added to an existing relational database system to allow it to support full logic programming functions. Implementation issues for each new function are discussed. We show how Horn-clause rules can be translated in...
