LEARNING THE JARGON

SETTING UP A DBMS (Data-Base-Management-System)

Read the text to understand particular terms related with the stages of setting up a DBMS.

Match the parts of word combinations, paying attention to the meaning of new words.

To have a) a DBM system

To set up b) access to a microcomputer

To eliminate c) title and subject cards

To combine d) duplicate records

To consist of e) two files

To identify f) eleven fields.

5. Read the following word-combinations with the new words and guess their meaning. Give the Ukrainian equivalents:

Subject catalogue; related records; to eliminate duplicate records; current data base; type of movie; movie title; entry of letters, numbers or characters; to shorten the description of the movies.

Now that you know the advantages of electronic files, let's set up a data base management system In order to learn how one works. Assume that you are In charge of your school's video library. You have access to a microcomputer and are interested in computerizing your ever-expanding catalogue. Since you already have a data base-a title and a subject card catalogue-you have a good idea of the kind of information that people want and how they can best find it. After consulting with the computer lab instructor, you buy a DBMS. You're ready to begin.

Before turning to the computer, you review the documentation that accompanies the program and become familiar with the terminology, or jar­gon, of a DBMS. You learn three important words: field, record,and file.

Field.Afield is a single category of information in your data base. It c an made up of numbers, letters, or a combination of numbers and letters. You look at a catalogue card in your current data base and identify eleven fields, including type of movie, movie title, and call number.

Record.A record is a collection of fields. Each catalogue card with all its entries about a single movie is a record. Since your catalogue currently consists of title and subject cards, you have two records for each movie listed in your data base.

File.A file is a collection of related records. Your subject catalogue is one file; your title catalogue is another. Your DBMS will eliminate duplicate records and combine the two files.

While every data base consists of fields, records, and files, some can handle more data than others. Say that this particular program allows 65 characters in a field, 12 fields in a record, and 300 records in a file. Each letter, number, or space in an entry counts as one character. You note that in setting up your DBMS you'll have to shorten the descriptions of the movies.
