033. How are errors reduced by using
a database system?
Because
there is Minimum Duplication of
data (Minimum, because some duplication is necessary) there will be Reduced
Errors. One of the objectives of an information system is to reduce human
involvement, since humans do tend to make a variety of errors that computers do
not. To further promote reduced errors, database designers can develop Controls
and Checks on the data. The primary intent of a database is to maintain data
integrity (e.g., to assure that some data can only contain certain values,
to make sure that there are no duplicate records, and so forth). These checks
and controls were difficult to establish using the traditional file system
since they require a lot of time and effort to establish, and programmers
didn't have the time to devote, given that they were constantly building new
systems for different applications.
