As more and more people turn to databases for both large systems and small web-based applications, misunderstandings arise about the precise meaning of terms like "join", "instantiation", "view", and others. Those misunderstandings can affect design and programming that lead to problems down the road. "The Relational Database Dictionary" is exactly what designers, programmers, students, and database administrators (DBAs) need, a single source where they can find precise definitions. Authored by C.J. Date, a respected expert who is widely regarded as the developer of relational database technology while at IBM, this pocket-sized dictionary is the definitive glossary of terms and concepts used with relational databases such as Oracle products, IBM's DB2, Microsoft's SQL Server, MySQL, and PostgreSQL. "The Relational Database Dictionary" provides structure and clarity that will help build proficiency and accuracy in working with today's relational databases. There is no other quick reference of this type available.
