It is the job of a program called a(n) to store and retrieve data in database tables.
A single-user database that is used by only one person at a time is called a(n) database.
A database that is used by more than one person at a time is called a(n) database.
databases were the first applications of database technology.
A(n) database is characterized by having 25 or fewer concurrent users and 100 megabytes or less data.
In database processing systems, the data is directly accessed only by the .
In database application processing systems, the user interacts directly with the .
The first business information systems stored groups of records in separate files and were called .
The most serious problem with data duplication concerns .
A collection of data has if it is logically consistent.
In file-processing systems, the of files and records are part of the application code.
A(n) is a self-describing collection of integrated records.
The description of the structure of a database is stored in the , also known as the data dictionary or the data directory.
In the standard data hierarchy, a byte, or character, is composed of .
In the standard data hierarchy, a field is composed of .
In the standard data hierarchy, a record is composed of .
In the standard data hierarchy, a file is composed of .
A(n) is used to represent relationships among the data and to improve the performance of database applications.
When the structure of a form or report is part of the database it is called .
The database is a(n) model because businesses change.
are representations of events that must be processed against the database.
A database is a model of the model or view of the business.
The database model stores data as tables, with rows and columns.
In the relational model, the process of is used to change an undesirable table into two or more desirable tables.
Originally, it was thought that the relational model would allow to obtain their own information from databases.
One impact of the movement of database technology from mainframes to microcomputers was the dramatic improvement in DBMS .
The use of multiple CPUs in processing database applications in LAN-based multi-user database architecture produced greater .
Of the two types of LAN-based multi-user database processing, is the more complex and robust.
Of the two types of LAN-based multi-user database processing, is the simpler and less robust.
A(n) database is logically integrated but physically located in more than one place.
Object-oriented database systems developed to handle the structures processed by .
The database is processed by the , which is used by both users and developers.
Today, most databases represent user data in , which are tables of data.
In a table of users’ data, the columns contain .
The process of is used to change poorly structured tables into well-structured ones.
Most DBMS products store metadata in tables, sometimes called .
One advantage to storing metadata in tables is that can use the same tools to query the metadata as they do to query the users’ data.
A type of database data that consists primarily of indexes is called .
Overhead data typically includes indexes and sometimes .
Indexes are useful for and search operations.
The structure and format of user forms, reports, and other application components are stored in the database as .
The subsystem contains tools to facilitate the creation of the database.
The subsystem processes the application components created using the design tools
The DBMS engine is the intermediary between the other DBMS components and the .
The DBMS engine receives requests from the other DBMS components and translates them into commands for the to read or write data from the physical media.
A database defines a database’s structure – its tables, relationships, domains, and business rules.
A database schema is a(n) .
A(n) is a set of values that a column may have.
are restrictions on the business’s activities that need to be reflected in the database and database applications.
A primary key from one table that is placed into another table to declare a relationship is called a(n) in the second table.
are identifiers that are created only to allow each row in a table to be uniquely identified and have no meaning to the users.
Queries can be expressed to the database using the data access language called .
QBE, which stands for , is a means of expressing a query to the database.
Queries can be , meaning that they are constructed to accept a criteria value at the time they are run.
A means of expressing a query to the database called allows the user to enter query constraints on a data entry form.
A(n) is a formatted display of data.
are used to organize application components to make them more accessible to the end user and to provide control over the users’ activities.
