of how an AIS can perform its three basic functions :1. To collect and store data about the

organization’s business activities and transactions efficiently and effectively

1 To collect and store data about the organization’s business activities and transactions efficiently and effectively: Capture transaction data on source

documents. Record transaction data in journals, which

2 To provide management with information useful for decision making:In manual systems, this information is

Learning Objective 2

Describe the documents and procedures used in an AIS to collect and process transaction data.

2-17Anup Kumar Saha

The Data Processing Cycle

The data processing cycle consists of four steps:

1. Data input

2. Data storage

3. Data processing

4. Information Output

2-18Anup Kumar Saha

The Data Processing Cycle

The trigger for data input is usually business activity. Data must be collected about:

1. Each event of interest

2. The resources affected by each event

3. The agents who participate in each event

2-19Anup Kumar Saha

Data Processing Cycle: Data Input

Historically, most businesses used paper source documents to collect data and then transferred that data into a computer.

Today, most data are recorded directly through data entry screens.

2-20Anup Kumar Saha

Data Processing Cycle: Data Input

Control over data collection is improved by: prenumbering each source document

and using turnaround documentshaving the system automatically

assign a sequential number to each new transaction

employing source data automation
