If checking an information item takes a fraction of a second, why is it that we can go through billions of information items in a fraction of a second?
In a relational data base, one stores a record with related fields as data.
In a relational database, tables do not need to be of the same size
Table for "Students grades"
Table for "Students' contact information"
Data models in which the relationship between higher and lower items are inherited.
Data are kept in different settings and on different computers. Distributed databases need not only addresses for where the data are but also need an audit trail
World Wide Web
Distributed Databases without data until need arises, less problems with privacy of patients
Structure makes it possible to process and analyze large amount of data
