FUNDAMENTALS OF DATABASE SYSTEMS (6TH EDITION): PART 1

20.1 OVERVIEW OF OBJECT-ORIENTED
CONCEPTS
This section gives a quick overview of the history and main concepts of object-oriented databases, or OODBs for short. The OODB concepts are then explained in more detail in Sections 20.2 through 20.6. The term object-oriented-abbrev[r]

Security enforcement deals with controlling access to the database system as a whole and controlling authorization to access specific portions of a database. The former is usually done by assigning accounts with passwords to users. The latter can be accomplished by using a sys[r]

Indexing Structures
for Fi les
In this chapter, we assume that a file already exists with some primary organization such as the unordered, ordered, or hashed organizations that were described in Chapter 13. We will describe additional auxiliary access structures called indexes, which are used[r]

The problem of efficiently implementing a view for querying is complex. Two main approaches have been suggested. One strategy, called query modification, involves modifying the view query into a query on the underlying base tables. The disadvantage of this approach is that it is inef[r]

common to use long integers as OIDs and then to use some form of hash table to map the OID value to the physical address of the object.
Some early OO data models required that everything—from a simple value to a complex object—be represented as an object; hence, every basic value,[r]
