Record-Keeping 4 Record-keeping is the process of creating and using lists of information. The information can refer to practically anything: a company's accounts receivable, the types of animals owned by a zoo, or the set of comic books owned by a teenager. All record-keeping is characterized by two factors. Records A record contains a number of pieces of information about a single item. These pieces of information are called the fields of the record. For example, a record describing a comic book might contain fields giving the name of the book, the issue number, and the month it was published. Lists A list is a collection of records which are related in some way. For example, you might have a list of records that all describe comic books. A large list is sometimes called a database. Files containing lists of records may be created in many different ways. One of the easiest is to use a text editor like vi. Type in the records one at a time, putting each record on a separate line. The fields should always be given in the same order. Often, it helps to separate fields with special characters so you can tell where one field ends and another begins. The file ROOTDIR/samples/guide/comic.txt contains a list of records describing a comic book collection. Have a look at it, using the pg command. You'll see that each line describes a single comic book, giving the series name, the issue number, the month of publication, the year of publication, and the price. Fields on a line are separated by colon (:) characters. We'll be using this file to demonstrate a number of MKS Toolkit commands that make it easy to keep track of records. The sort of operations we will do here can be performed on any record list you might have. Basics of the MKS Toolkit 17
