Role: Software Engineer

Project Description

• This project was built using Visual Basic and it can run on computers that have the .NET
• Framework installed. We divided the whole project into five main modules: employee data, payroll
• records, rates, ledger and help. When a data is saved, the data gets written into an XML file. Keeping in line with making the software platform-independent, XML is also a highly platform-independent format for storing data. This is where all the data of the employee is stored, along with each month's payroll data for the employee.
• The most important modules of the design are the employee data, payroll records and rates. For the
• employee data module, we had to keep track of the identification number, name, union membership
• status, pension plan agreement and payroll of an employee. We also had to link these to a general
• module that will hold all the other employees. There had to be a means of storing all these data,
• retrieving them, adding data and deleting data without giving any errors. From the employee data
• module, we had to create a link to the employee's pay records.
• The payroll records had to contain the number of hours that the employee had worked and in what
• month and year that the employee worked. We also had to keep in mind the rate with which we
• would be able to calculate the employee's pay. The payroll records also had to contain the employee's
• deductions, that is, the deductions from the pension plan, union membership fee and taxes.
• Obviously, the payroll records also had to contain the gross and net pay of the employee.

Environment: Visual Basic .NET, XML.

Project Description

• Library Management System is a console application developed using the C programming language. We can perform book-related operations like in a REAL library management system with computer. Those include functions such as Add books, Return books, Issue books, Delete record of books issued, View record of books issued, Search for books, and more.
• File handling has been extensively used in this project for almost all functions. For library management, this project considers six departments Computer, Electrical, Civil, Electronics, Mechanical and Architecture. These departments work simultaneously with the operations mentioned above. You can add a book to the Civil section, delete a book from the Electrical section or view issued book details of the Mechanical department

Environment: C Language, MS Access database.
