Components of Computerised Accounting System (CAS)
- Procedure :- Logical step by step sequence of activities to be followed to perform a task.
- Data :- Raw facts and figures used by a computer.
- People :- Humanware including users.
- Hardware:- Physical parts and network of computers.
- Software :- All programs which puts hardware into function.
Data and Information
Data is raw, unorganized facts that need to be processed. Data can be something simple and useless
until it is organized.
When data is processed, organized, structured or presented in a given context so as to make it useful, it is called information
Data -> | Process -> | Information |
Hourly Rate = 20Hours worked = 12 | 20 hours X Rs.12 | Total wages = Rs 240 |
Accounting Cycle
- Recording transaction in journal
- Posting of journal entries to ledger account
- Preparation of Trial balance from balance of accounts
- Passing adjusting entries
- Preparation of adjusted Trial balance
- Passing closing entries
- Preparation of Financial statement
Grouping of Accounts
Grouping of accounts is the process of classifying the ledger accounts and organising them under major heads of accounts.The group of accounts determines where to place a particular ledger accounts under trading A/c ,Profit and loss A/c or balance sheet.
There are four groups of accounts :Assets,liabilities,Income and Expenditure.

Codification of Accounts
Giving a numerical number or alphabet or both to a particular account for identification is known as
Codification of Accounts.
For example, the primary code ‘1’ can be given to Asset, ‘2’ to Liabilities, ‘3’ to Income and ‘4’ to Expenditure.
Again for fixed assets the code can be given as 1.1 and the current assets can be coded as 1.2. Thus Building under Fixed Assets can be coded as 1.1.1 and Furniture can be coded as 1.1.2, Cash Account can be coded as 1.2.1 and so on
Types of Codes
Sequential Codes
In sequential code,numbers and/or letters are assigned in consecutive order.
These codes are primarily applied to source documents such as invoices, cheques etc.
Ex : N001 – ABC Ltd
N002 – PQR Ltd
N003 – XYZ Ltd
Block codes
In block code, a range of numbers is partitioned into a desired number of sub ranges and each sub range is allotted to a specific group.
Code Account Groups
001 – 500 Direct Expense
501 – 1000 Indirect Expense
1001- 1500 Direct Income
1501- 2000 Indirect Income
Mnemonic Codes
A mnemonic code consists of alphabets or abbreviations as symbols to codify an Account.
E.g. Salary Account can be coded as ‘SLR’, Building Account can be coded as ‘BLD’ and so on

Methodology to develop coding structure and coding
The coding system should be pre-planned by considering the scope and features of the piece of information.The codes should be designed to accommodate future additions.The hierarchy of data names should be strictly considered while developing codes.
Security Features of CAS Software
Every Accounting Software ensures Data Security, Safety and Confidentiality by providing the features like Password Security, Data Audit and Data Vault
1 – Password Security
Password is the key to allow access to the system. Computerised Accounting system protects the unauthorized persons from accessing the business data. Only authorized people who are supplied with the password, can enter the system.
2 – Data Audit
It enables one to know as to who and what changes have been made in the original data.
3 – Data Vault
Software provides additional security through data encryption. Encryption means scrambling the data so as to make its interpretation impossible
