Infosys Project Specification for Unix

1 OVERVIEW

To develop a Department Maintenance system involving department and employeeinformation.

1.1 CURRENT SYSTEM

Manual entry using Ledger books.

1.1.1 Limitations of the Current System

a) The current system is not accessible to users present in different locations of the

organization.

b) The user needs to keep track of all employee related data.c) Searching for relevant information is time-consuming.

d) Updation is manual and often leads to inconsistency.

1.2 PROPOSED SYSTEM

The system to be built needs to overcome the above limitations.

1.2.1 Objectives of the Proposed Systema) The application should be accessible to the authorized users in different

locations.

b) Relevant data like Employee Number, etc need to be automatically generated,and should involve least human intervention.

c) Search should be faster and should be flexible with multiple options.

d) Data Consistency and Integrity should be maintained.

ER// CORP/CRS/OS04/006 Version No. 1.1 1




2 BUSINESS REQUIREMENTS

1. To maintain department codes.

2. To maintain Employee Master.3. To enquire Department details.

2.1 System Requirements

2.1.1 Scope & Boundary

a) The enquiry is to be based only on department code and not on employee code.

b) The system need to make use of simple plain file system. No databasetechnology usage.

2.1.2 Context Diagram

The Level 0 Context diagram for the proposed system is as follows:


Department

Maintenance

EmployeeData Entity

DepartmentData Entity

Display

Employee

Data Store

Department

Data Store




2.2 Business Events

2.2.1 External Events

While running the above application if the key ^C is hit, a message “ Do you really

want to quit (y/n)” should be displayed. If the user hits y or Y, control comes out of

the application. If any key other than Y,y N,n is entered message “Invalid Choice” isdisplayed.

2.3 Inputs and Outputs

Input Entities area) Department data

a. Department Code. (max 4 chars)

b. Department Name. (max 15 chars) b) Employee Data

a. Employee Id (max 4 chars)

b. Employee Name (max 25 chars)c. Department Code (max 4 chars) - generated by system.

d. Location (max 5 chars)

2.4 Relationships

Every employee in this system has a department code, which needs to be existent inthe department data store (dept file).

2.5 Precedence Relationships

The department creation must precede the employee creation in a particular

department.





2.6 Screens

Note for all screens:

• All the fields with ………are user inputs.• All fields with ________ are to be generated by the system.

• All error messages are to be displayed at the bottom of the screen.

• When an error message is displayed system should wait for a key press.

• All validations done should be case insensitive. For e.g. when you ask the user if he

wishes to continue, following inputs are valid: ‘y’ or ‘Y’ or ‘n’ or ‘N’. Any other

input is invalid.

• The display should be visually appealing.

(Note: You could use commands like “tput” for the same. Kindly go through the

documentation of “tput” using “man” command for further information.)

3 OPERATING ENVIRONMENT REQUIREMENTS

3.1 Hardware

Server-side

Hardware satisfying Unix Operating System requirements.Client-side

Dumb Unix terminal (could also be software simulated like Telnet, etc).

3.2 Software

Server: Any Unix flavour.Client: Any Unix client utilities like Telnet, Cygwin, etc.

3.3 Network

Connection over LAN, etc.

3.4 Communication

Typically TCP/IP based communication protocols.





4 FUNCTIONAL REQUIREMENTS

Department Maintenance:

This module will have one main function:a To Add department codes

Add Department:

2 fields: Department Code, Department Name

• The department code should start with 1000. Every new department added

should get a 1 up number for the department code.

• The department codes should be unique

• Department names cannot be duplicated. Comparison should be case insensitive.

• The department codes should be generated by the system.The add department screen should have provision for adding new departments as long as the user

wishes. When the user finishes adding new departments, the control should return to theDepartment Code Maintenance Screen.

Assume that the user always enters a name less than or equal to 15 characters. Novalidation is required for this field. A Record is inserted into dept.dat file with ‘:’

as the delimiter between the 2 fields xxxx:xxxxxxxxxxxxxxx

Employee Master

This module will have one main function:a To Add new Employees

Add New Employees:

4 fields: Employee Id, Employee name, Dept Code, Location.

•

The employee id should start with 1000. Every new employee added should get a1 up number for the employee id.

• The employee ids should be unique

• The employee ids should be generated by the system.

• When the control comes to accepting the department code, list the existing

department codes along with their names on the screen for selection of the proper

department code.





• Department Code must be a valid code (should be existing in Department

Maintenance file)

• Department name is displayed corresponding to the code entered. User should

not edit this field.

• The add employee screen should have provision for adding new employees as

Assume that the user always enters a name less than or equal to 25 characters and a

location not exceeding 5 characters. No validation is required for the length of these2 fields. A Record is inserted into emp.dat file with : as the delimiter between the 4

fields

xxxx:xxxxxxxxxxxxx:xxxx:xxxxx

Department Enquiry

This module should have:a Enquiry on department code

Enquiry on Department Code:

• Department code should exist.

• If the department code does not exist, an error message should be displayed, and

department.

• If the department code exists, the details of all the employees in that department

should be displayed in sorted order.

• The enquiry by department screen should have provision for enquiry on different

departments as long as the user wishes.

• When the user finishes enquiry by department, the control should return to the

Department Code Maintenance Screen.

• The result is displayed on the screen and also diverted to a file dept.rep.





5 STANDARDS REQUIREMENTSProper coding standards need to be followed to ensure readability.

6 USER REQUIREMENTS

6.1 Features Required

• Login should lead to creation of dept.dat and emp.dat files in the proper directory. No

change if the files already exist.

•

By typing mkworkdir all the user directories should get created. If already createdMessage “Dir exists” is displayed
