\begin{document}

Databases are a collection of files holding related data.

Almost anything can be viewed as a database.

Goal of database management systems is to provide a convenient and
efficient way to search/store/ and manipulate.

\begin{itemize}

\item history:

\item database uses:

\item tools

\end{itemize}

application programmer job gets easier -\(>\) database management
system is harder to make (more intelligent).

application programmers jobs will go away as databases make everything
easier.

There are 3 views of databases:

\begin{itemize}

\item external view seen by user, could be multiple views

\item conceptual view, relates application to DBMS, seen by application
programmer, defined by database makers

\item internal view, how data is actually stored. Defined to optimize conceptual
view.

\end{itemize}
