Employee Management System 1. INTRODUCTION

This project has been designed to solve the problems, which are likely to be faced by the employees of the department at the time of calculating the Salary Details of employees. The project has covered almost all the necessary data, which is required for Employee anagement System. The main purpose of the project is to save time, money and to remove heavy workload of the employees.

Database Management System

Every organi!ation maintains data pertaining to its business, students and employees and other topics. This data needs to be maintained in such a manner that it is easily available and can be presented in desired formats. This data also updated on regular basis. 1 What is Database? Database anagement System as the name suggests is used for managing information and data. D" S consists of a number of database programs, which help a user in entering and managing information or data electronically. Data management involves creating, modifying, deleting and adding data files and using this data to generate reports. Thus, a D" S is a collection of data and program that help you to retrieve this data and perform operations on it. ost database management system has the following facilities#capabilities. i$ ii$ iii$ iv$ definition. ICDEOL HPU 2 %reating of a file, addition to data, deletion of data, modification of data, creation, addition and deletion of entire files. &etrieving data collectively or selectively. The stored data can be sorted ore inde'ed at the user(s discretion or direction. )arious reports cab is produced from the system. These may either be standardi!ed reports or that may be specifically generated according to specific user

Employee Management System
v$ vi$ athematical functions cab be performed and the data stored in the database can be manipulated with these functions to perform the desired calculations. To maintain data integrity and database use. The D" S interprets and processes user requests to retrieve information from a database. They may be keyed directly from a terminal or coded as high level language programs to be submitted for interactive or batch processing. *n most cases a query request will have to penetrate several layers of software in the D" S and operating before the physical database can be accessed.

Queries DBMS Operating System COBOL/PASCA/FORTRAN Data Base

The D" S responds to a query by invoking an appropriate sub+program, each of which performs its special function to interpret the query or to located the desired data in the database and present it in the desired order. Thus, the D" S shields database users from the tedious programming they would have to do to organi!e data for storage, or to gain access to it once it was stored. ,s already mentioned, a database consists of a group of related files of different record types and the D" S allows users to access data anywhere in the database without the knowledge of how data are actually organi!ed on the storage device. The role of D" S as an intermediary between the users and the database is very much like the functions of a salesperson in a consumer(s distributor system. , consumer ICDEOL HPU 3

Employee Management System
specifies desired items by filling ort an order form, which is submitted to a sales person at the counter. The sales person presents the specified items to consumer after they have been retrieved from the storage room. %onsumers who place orders have no idea of where and how the items are stored- they simply select a desired item from an alphabetical list in a catalogue. .owever, the logical order of goods in the catalogue bears no relationship to the actual physical arrangement of the inventory in the storage room. Similarly, the database user needs to know only what data he or she requires, the D" S will take care of retrieving it. D" S that is built upon entity relationship model is known as &elational D" S. /, &elational Database is a database that allows to group its data into one or more discrete tables that can be related to one another by using common to each other related tables(.

D MS Use!s" The users of a D" S can be classified as 0a1ve users, 2nline, users, ,pplication 3rogrammers, and Database ,dministrators . Data Manage!" The data manager is the component of the D" S that provides an interface between the user and file system. &esponsibility for recovery of the database after any failure lies with the data manger. #i$e Manage!" &esponsibility for the structure of the files and managing the file space rests with the file manager. The file manager can be implemented using interface to the e'isting file subsystem provided by the operating system of the host computer. Dis% Manage!" The disk manager is part of the operating system of the host computer and all physical input and output operations are performed by it. The disk manager transfers the block or page requested by the file manager so that the later need not be concerned with the physical characteristics of the underlying storage media. Data ase" , Database is a computer term for a collection of related information about

a certain business topic or business application, such as in employee database or a product database.

The DD4 compiler coverts the data definition statements into a set of tables and these tables contain information concerning the database and are in a form that can be used by other components of the D" S. Database Manage!" , database manager is program module that provides the interface between the low level data stored in the database and the application programs and queries submitted to the system. *t is responsible for interfacing with file system. ()e!y P!'cess'!" The database user retrieves data by formulating a query in the data manipulation language provided with the database. The query processor is used to interpret the online users query and convert it into an efficient series of operations in a form capable of being sent to a data manager for e'ecution. The query processor uses the data dictionary to find the structure of the relevant portion of the database and uses the data dictionary to find the structure for the relevant portion of the database and uses this information in modifying the query and preparing an optimal plan to access the database. Database A*minist!at'!" 2ne of the main reasons for having D" S is to have control of both data and programs accessing that data. The person having such control over the system is called the Database ,dministrator 5D" $. The D", administers the three levels of the database and in consultation with the overall user(s community, sets up the definition of the global view or conceptual levels lf the database.

INTRODUCTION TO MS+ACCESS S+,ccess is powerful multi+user D" S developed by icrosoft %orp. it can be used to store and manipulate large amounts of information and automated repetitive tasks such as maintaining an inventory and generating invoices. "y using ,%%ESS, one can develop easy+to+use input forms. 7ou can process your data and create meaningful reports. Data in ,ccess is organi!ed in the form of table. 8ithin a table, records are arranged according to a common reference value, known as the primary key or the key field. The value in the key field is different for every record and thus helps in uniquely identifying records. ost database applications comprise of a /"ack+end( and a /6ront 9end(. The /"ack+end( part of the application is the one that takes care of storing and retrieving the data. The / 6ront+end( on the other hand, provides a user+interface or a means by which the user can interact with the data in the back+end. The user of a particular application usually only interacts through the front end. The comprises usually of /forms(, which present the data in an attractive and user friendly manner. *t is these that are used to add, modify or generally manipulate data in the tables. What is ACCESS? S+,%%ESS is a &D" S 5&elational Database anagement System$ under 8indow. *t is used to store and manipulate large amounts of data. The data is stored in multiple tables. , relational database utili!es two or more tables, containing data arranged in rows and columns, to cross+reference and define relationships between the data. *n contrast, a flat+file database is limited to a single table.

, relation database breaks the /big picture( into smaller, more manageable prices. e.g: if we were gathering information about a new product line, each type of information+ product, seller, and distributor would be stored in its own, related table, rather than in one large, all+inclusive table.

DATA ASE O 5ECT 1 Tab$e" + Tables are the fundamental structures in an ,%%ESS database because they store the data. They are a collection of data about a specific entity. They organi!e data into columns called fields and rows called records. , common field relates two table so that data can be viewed from more that one table at a time. %licking this tab displays a list of all tables in current database. 6rom here we open Dr modify the design of an e'isting table or create a new table. 6 ()e!y" + , query is a tool for asking questions about the data in tables and for performing actions on data. Gueries can answer questions, such as how many customers live on a particular street and what are their phone numbersH Gueries are used to e'tract information from a database. , query can be used to select a group of records that fulfill a certain condition- specific fields from multiple tables can be combined into a single database sheet. The database sheet that the query returns is called dynaset 5that is a dynamic set of data that can be changed according to the data in the source table$. 8e can use queries to combine or join data from many separate but related tables. Gueries can also help us change, delete or add large amount of data in one fell swoop. 6inally, we can use queries as the basis for forms and reports. =. #'!ms" + 6orms display and print data from a table or a query. 6orms enable us to view, edit and print data in a customi!ed format that resembles fill+in+the+blanks form. Data entry forms help the user to enter information into a database table in an easy, interactive and accurate manner. The data entry forms and display forms provide a more structured view of data as compared to a data sheet. ,%%ESS provides several different ways of creating data entry forms, these include crating the form by tool bo' providing various controls in design view as well as a number of wi!ards that take the user through form creation process. 6orms can be plain and simple or quite elaborate with graphics, lines and automatic lookup features that make data entry quick and easy. 6orms can even include other forms called sub+forms that let us enter data into several tables at once, depending upon their behavior.

PRO LEM DE#INATION The project is based on the Emp$'yee management system. *n a manual working with in the organi!ation the records related to employees like employee 0ame, Date of Joining etc are kept in a old files and salary details of each employee within the organi!ation were calculated and processed manually by a clerks in the departments. *n this manual system salary details for each employee should be prepared at the end of each month, this was a quite time consuming job for clerk to process and calculate salary details for each employee with in the organi!ation. Sometime it may also happen that these salary details produced manually is error+prone. To reduce the above mentioned problem with in the current e'isting system, the project is developed to replace it with the computeri!ed automatic one, after the current system gets computeri!ed the salary details and other details related to a particular employee in stored in the database of the system so that one can get details later when needed.

SYSTEM TESTING

,fter the programs are tested individually, the system as a whole needs to be tested. During testing, the system is used e'periment all to ensure that the software does not fail i.e. runs according to specifications and in the way the users e'pect it to. Special test data is prepared as input for processing and the results are e'amined to locate errors or une'pected results. The persons other than those who wrote the original problem perform testing. Different levels of testing are: DE UGGING AND TESTING Debugging and testing are vital stages of implementation phase. 8ithout these we cannot be sure of the quality of his software. Debugging is the process of isolate and correcting the causes of known errors. Debugging process is applied after coding ad again after coding and again after testing, because during compilation of code system is corrected and during testing logical errors is removed two types of testing is performed on the system. 1. Unit testing *n unit testing each program of each module is testifying using separately for its correctness. They are tested under all relevant condition using dummy data.
