LEAVE MANAGEMENT SYSTEM

The main objective of the proposed system is to decrease the paper work and easier record maintenance by having a particular website for attendance, leaves and notice maintenance.
Initially attendance is taken by using the attendance register in the college for staff. Staff needs to submit their leaves manually to their respected higher authorities.
This increases the paper work at the same time maintaining the records is more tedious. Maintaining the notices in the records also increases the paper work.
In the current system, an attendance register is maintained at the front-office and employees enter their in and out times. The Hod department does the attendance and leave calculation manually at the end of each month. This increases the paper work and makes the record maintenance tedious.
The proposed system automates the existing system. It decreases the paper work and easier record maintenance by having a Database for attendance, leaves and notice maintenance.
The database maintains the information about the attendance, leaves and notice. It reduces the time and manual paper work for apply a leave.
The Leave Management System reduces the over work and risk of the HOD/Principal.
This tier includes all the HTML content or forms to be displayed on the client browser. It is the form which provides the user interface to end user. Programmer uses this tier to get or set the data back and forth.
Business Logic Layer
In the Business logic tier, the actual processing of the data and the logic behind the implementation of the application will be present. This tier can contain a class, which can be used to write the functions, and also works as a mediator between the presentation tier and data tiers.
Data Tier contains methods and classes that deal with passing and storing data to the data Storage Layer. Queries or stored procedures are used to access the data from the database or to perform any operation to the database. It stores the data passed by the presentation tier.
Microsoft. NET Framework
The .NET Framework is a new computing platform that simplifies application development in the highly distributed environment of the Internet. The .NET Framework is designed to fulfill the following objectives:
To provide a consistent object-oriented programming environment whether object code is stored and executed locally, executed locally but Internet-distributed, or executed remotely.
To provide a code-execution environment that minimizes software deployment and versioning conflicts.
To provide a code-execution environment that guarantees safe execution of code, including code created by an unknown or semi-trusted third party.
To provide a code-execution environment that eliminates the performance problems of scripted or interpreted environments.
To make the developer experience consistent across widely varying types of applications, such as Windows-based applications and Web-based applications.
To build all communication on industry standards to ensure that code based on the .NET Framework can integrate with any other code.
The .NET Framework has two main components: the common language runtime and the .NET Framework class library. The common language runtime is the foundation of the .NET Framework. You can think of the runtime as an agent that manages code at execution time, providing core services such as memory management, thread management, and remoting, while also enforcing strict type safety and other forms of code accuracy that ensure security and robustness. In fact, the concept of code management is a fundamental principle of the runtime. Code that targets the runtime is known as managed code, while code that does not target the runtime is known as unmanaged code.
