Chapter 4 Accounting Information Systems 157
accounting equation: Assets = Liabilities + Stockholders’ Equity. Because of this double
equality, the system is referred to as the double-entry accounting system.
To summarize, each transaction is recorded under the rules shown in Exhibit 3.
Under these rules, the total debits will equal the total credits for each transaction,
because the equality of the debits and credits is built into the accounting equation:
Assets = Liabilities + Stockholders’ Equity.
The Journal
Each transaction is initially entered in chronological order in a record called a journal.
In this way, the journal documents the history of the company. The process of record-
ing transactions in the journal is called journalizing. The specific transaction record
entered in the journal is called a journal entry.
In practice, most journal entries are automated with the transaction processing sys-
tem. However, transactions that are unusual, correcting, or infrequent may require
manual entries. We stress manual entries in this text to help you understand the auto-
mated framework.
A business may use a variety of formats for recording journal entries. It may use one
all-purpose journal, sometimes called a general journal, or it may use several journals. In
the latter case, a special journalis designed to record a single kind of transaction that oc-
curs frequently. To simplify, we will use a basic, two-column general journal in the re-
mainder of this chapter to illustrate the manual journalizing of transactions.
