In the section “Disadvantages of File Processing Systems,” the statement is made that the disadvantages of file processing systems can also be limitations of databases, depending on how an organization manages its databases. First, why do organizations create multiple databases, not just one all-inclusive database supporting all data processing needs? Second, what organizational and personal factors are at work that might lead an organization to have multiple, independently managed databases (and, hence, not completely follow the database approach)?
The drawbacks of file processing systems may also be limits of databases, according to the section "Disadvantages of File Processing Systems," which states this. To begin, why do companies have numerous databases when they might have a single database that could handle all of their data processing requirements? In other words, what are the organizational and individual variables at play that might cause a company to have several, separately maintained databases?
A database system has taken the role of the traditional file processing system. In the case of this new database strategy, there are a number of advantages. However, despite its many benefits, the database system has several downsides that should be examined in further detail.
