Database Basics
The purpose of a database is to store the day-to-day operational information required by
an organization. Any means of collecting and organizing data is a database. Prior to the
Information Age, information was primarily stored on cards, in file folders, or in ledger books.
Before the adding machine, offices employed dozens of workers who spent all day adding
columns of numbers and double-checking the math of others. The title of those who had that
exciting career was computer.
As the number crunching began to be handled by digital machines, human labor, rather than
being eliminated, shifted to other tasks. Analysts, programmers, managers, and IT staff have
replaced the human “computers” of days gone by.
Benefits of a Digital Database
The Information Age and the relational database brought several measurable benefits to
organizations:
? Increased data consistency and better enforcement of business rules
? Improved sharing of data, especially across distances
? Faster searches for and retrieval of data
? Improved generation of comprehensive reports
? Improved ability to analyze data trends
The general theme is that a computer database originally didn’t save time in the entry of
data, but rather in the retrieval of data and in the quality of the data retrieved. However, with
automated data collection in manufacturing, bar codes in retailing, databases sharing more
data, and consumers placing their own orders on the Internet, the effort required to enter the
data has also decreased.
Tables, Rows, Columns
A relational database collects common, or related, data in a single list. For example, all the
product information may be listed in one table and all the customers in another table.
A table appears similar to a spreadsheet and is constructed of columns and rows. The appeal
of the spreadsheet is its informal development style, which makes it easy to modify and add
to as the design matures. In fact, managers tend to store critical information in spreadsheets,
and many databases started as informal spreadsheets.
In both a spreadsheet and a database table, each row is an item in the list and each column is
a specific piece of data concerning that item. So each cell should contain a single piece of
data about a single item. While a spreadsheet tends to be free-flowing and loose in its design,
database tables should be very consistent as to the meaning of the data in a column. Because
row and column consistency is so important to a database table, the design of the table is
critical.
Over the years different development styles have referred to these columns with various
different terms, listed in Table 2-1.
