Описание: In this unit, our focus will be shifted to look at how data are physically held in secondary storage (such as magnetic or optical disks). We will not only study the most important physical organisations of data, but also discuss the management of such physical organisations. Although an ordinary user of an off-the-shelf DBMS package (such as Oracle) is unlikely to have much control over the physical aspects of the DBMS, an understanding of the materials presented in this unit is still valuable when making decisions about the performance responses of the database system. It is also important to have the knowledge in order to assess the overall storage requirements for a database application to be developed. (Chapter 6 Part 1)
