| Tóm tắt: | • Part I (four chapters) provides a broad introduction to the concepts of database
systems in general and relational systems in particular. It also introduces the
standard database language, SQL.
• Part II (six chapters) consists of a detailed and very careful description of the
relational model, which is not only the theoretical foundation underlying relational
systems but is, in fact, the theoretical foundation for the entire database
field
• Part III (four chapters) discusses the general question o f database design. Three
chapters are devoted to design theory, and the fourth considers semantic modeling
and the entity/relationship model.
• Part r v (two chapters) is concerned with ưansaction management (i.e., recovery
and concurrency controls).
• Part V (eight chapters) shows how relational concepts are relevant to a variety of
further aspects of database technology— security, distributed databases, temporal
data, decision support, and so on.
• Part VI (three chapters) describes the impact o f object technology on database
systems. Chapter 25 describes object systems specifically; Chapter 26 considers
the possibility of a rapprochement between object and relational technologies and
discusses object/relational systems; and Chapter 27 addresses the relevance to
databases o f XML. |
