PROJECT DETAILSy What is Attendance Management System?

Attendance Management System is software developed for daily student attendance in

schools, colleges and institutes. If facilitates to access the attendance information of a

particular student in a particular class. The information is sorted by the operators, which

will be provided by the teacher for a particular class. This system will also help in

evaluating attendance eligibility criteria of a student.

y Purpose & Scope:-The intention of developing Attendance Management System is to computerized thetradition way of taking attendance. Another purpose for developing this software is to

generate the desired reports automatically at the end of the session or in the between

of the session as they require.

This project is basically a desktop application which means self contained software runs

on the system on which it has been installed under the user control and it will work for a

particular institute or college only.


5/21

For this application we have provided the following modules and features.

Admino Add & Modify details of

student faculty subject (if required)

Office Staffo Generate various types of reportso Send notice to black listed Students

Facultyo Attendance on basis of

subject day by day

o Check various generated Reports

EXISTING SYSTEM

The type of the system any institute uses always plays an important role in management of the

institute. Better the form, efficiency and accuracy of the system, the easier would be the management

tasks

Since the existing Attendance Management System of the Institute is totally working manually.

All the Informations are handled manually in the registers or other documents.

The process of the work is mainly divided in two parts, first is to take attendance on sheet &

enter details into the registers. And then at the end of the session or semester attendance is calculated

manually & reports are generated.


7/21

LIMITATIONS OF THE EXISTING SYSTEM

The Current system is completely manual. So the wastage of time occur the most over here. Intodays circumstances where there is cut-throat competition, nobody can afford wasting

precious time. Therefore, in todays do or die world, time makes a huge sense.

Daily reports of the system are done manually so it is more time consuming & one person of theorganization is reserved with this work so it is also wastage of the human resource. This

employee could be used for some other productive work for organization.

Security of data is less in manual systems. This because majority of the records are stored asstatements or in registers. Moreover, these data can be accessed by anyone and even they can

modify any important data.

There are large amount of data, accessing any data from the manual system is very difficult .The employee would have to go through each and every record sequentially until they find the

required data. This process is a tedious process when there are many records

Each & every organizations want their work to be done accurately. For this purpose, they havevery efficient employees who can work accurately. But, there is always a possibility of

occurrence of errorsmeans accuracy is less which may lead in many problems


8/21

PROPOSED SYSTEM

This Application is built for automating the processing of attendance. It also enhances the speed

of the performing attendance task easily. It also generates periodic reports to keep a check on the

students who are regular & who are not.

A Faculty has to login to the system & then in the attendance option they have to select

appropriate class, semester and subject. So this will display the list of the students who are eligible to

appear in this session. So now the faculty has to just select the students name from the manual

attendance sheet according to their roll number and then submit the sheet. This will add the selected

students as present student in that particular session.

This system is very useful to the office staff also because they can generate various types of

reports and submit them to respective faculties also or also can be submitted to the College

Coordinator. Office staff can also generate black list of students who have attendance less than 50% or

80%. So this kind of various reports can be generated


9/21

ADVANTAGES OF THE PROPOSED SYSTEM

A Computer can work more efficiently then compared to a human being. The work becomeseasy for the employees and thus, some amount of human resources is saved.

Data accuracy is maintained. Accurate information can be achieved within a short span of time

Data can be accessed easily and randomly. This also saves a lot of time.

Data is protected with the help of login system. Because of this login system, unauthorizedpersons cannot access the data.

Complexity of the work can be reduced by using the system which was not possible in manual orsemi-automated system. So it saves the time utmost.

FEASIBILITY STUDY

y Feasibility StudyA feasibility study is a short, focused study, which aims to answer a number of questions

y Does the system contribute to the overall objectives of the Organization?y Can the system be implemented using current technology and within given cost and

schedule constraints?

y Can the system be integrated with systems which are already in place?

Economically FeasibilityThe system being developed is economic with respect to School or Collages point of

view. It is cost effective in the sense that has eliminated the paper work completely.

The system is also time effective because the calculations are automated which are

made at the end of the month or as per the user requirement.

The result obtained contains minimum errors and are highly accurate as the data is

required.

Technical feasibilityThe technical requirement for the system is economic and it does not use any other

additional Hardware and software.

Behavioral FeasibilityThe system working is quite easy to use and learn due to its simple but attractive

interface. User requires no special training for operating the system.

ENTITY RELATIONSHIP DIAGRAM

-An entity-relationship diagram is a data modeling technique that creates a graphical

representation of the entities, and the relationships between entities, within an information system.

The three main components of an ERD are:

y The entityis a person, object, place or event for which data is collected. For example, if youconsider the information system for a business, entities would include not only customers, but

the customer's address, and orders as well. The entity is represented by a rectangle and labeled

with a singular noun.

y The relationship is the interaction between the entities. In the example above, the customerplaces an order, so the word "places" defines the relationship between that instance of a

customer and the order or orders that they place. A relationship may be represented by a

diamond shape, or more simply, by the line connecting the entities. In either case, verbs are

used to label the relationships.

y The cardinalitydefines the relationship between the entities in terms of numbers.An entity maybe optional: for example, a sales rep could have no customers or could have one or many

customers; or mandatory

The steps involved in creating an ERD are:

y Identify the entities.y Determine all significant interactions.y Analyze the nature of the interactions.

Entity Relationship Diagram Notations

Peter Chen developed ERDs in 1976. Since then Charles Bachman and James Martin have added some

slight refinements to the basic ERD principles.

EntityAn entity is an object or concept

about which you want to store

information.

Weak Entity

Attributes are the properties or

characteristics of an entity.

Key attribute

A key attribute is the unique, distinguishingcharacteristic of the entity. For example, an

employee's social security number might be

the employee's key attribute.

Multivalued attribute

A multivalued attribute can have more than

one value. For example, an employee entity

can have multiple skill values.

Relationships

Relationships illustrate how two entities

share information in the database structure.

DATA FLOW DIAGRAM

A data flow diagram (DFD) is a graphical representation of the "flow" of data through

an informationsystem. It differs from the system flowchart as it shows the flow of data

through processes instead of hardware.

The DFD a way of expressing the system in a graphical format in a modular design

was developed by Larry Constrains. This DFD is also known as Bubble Chart has the

purpose to classify the system requirement and to identify the major information that

will be a program in system design.

A Data Flow Diagram is logical model of the system and shows the flow of the dataand the flow of logic so this all thing describes what takes place in a proposed system,

not how the activities are accomplished.

We have noted that the DFD describes what the flow is rather then how they are

processed, so it means the DFD doesnt depend on the hardware, software, data

structure or file organization.

DFD consist of a series of symbols joined together by a line. There may be a single

DFD for the entire system or it may be exploded into various levels.

DATA DICTIONARY

In database management system Data Dictionary is a file that defines the basic organization of a

database. A data dictionary contains a list of all files in the database, the number of records in each file,

and the names and types of each field. Most database management systems keep the data dictionary

hidden from users to prevent them from accidentally destroying its contents. Data dictionaries do not

contain any actual data from the database. Without a data dictionary, however, a database

management system cannot access data from the database.
