S'STEM ANAL'SIS E(ISTIN) S'STEM
The
e!isting system
does
not
provide the
user
the
convenient that the proposed system provides. The Sta has to not maintain portable Student attendance System in smart phone application based. There is no user "reference login based Time Table Displayed in class wise and Sta wise Time table generate in android obile Application . DEMERITS OF T*E E(ISTIN) S'STEM
The most important dra#back of the e/isting system is that Staff has
to totally depend on the Student Attendance 3ook at the time of need. Another demerit of the e/isting system is that the process of obtaining the Time Table is not an easy task.
PROPOSED SYSTEM The system #ill overcome all the ambiguity. The project provides the
fle/ible" reliable" simple and most po#erful system to get the list of Time Table from Staff #ise and *epartment #ith Class Wise %eport 2enerated. The project consists of three users namely admin" Staff" Student" This applications organi!ed
based user login &references can register their details and through mobile application the users can find the easily and re)uest for their help. FEATURES OF PROPOSED SYSTEM
The most important feature of the proposed system is that the sta can access time table hour wise report with subject
The feature of the proposed system is that the system provides a list of Student of that particular Attendance speci#ed class for which the user has re$uested present or Absent.
Another important feature of proposed system is that it is easy and e%cient to use.

Bn contrast to other database management systems, SMGite is not a separate process that is accessed from the client application, but an integral part of it. SMGite read operations can be multitasked, though writes can only be performed se$uentially. SMGite is a popular choice for local)client storage on

<3SYSTEM DESI+N AND DEVELOPMENT Design is de#ning a model of the new system and continues by converting model to a new system. The method is used to convert the model of the proposed system into computer speci#cation. Data models are converted to a database and processes and Oows to user procedures and computer programs. The detailed design starts with three activities, database design, user design and program design. Database design uses conceptual data model. 1ser procedures designs use those parts of the DPD outside the automation boundary for designing. DATA FLO/ DIA)RAM
The data Oow diagram 5DPD7 is one of the most important tools used by system analysts. There are four components in DPD. "rocess, terminators, data Oow, and data source are the four components of DPD. 2ircles are used to represent the process, data Oows are represented using a thin line with arrow, the terminators are represented using rectangle and the data source is represented as an open 4 ended rectangle. 1nlike detailed Plowchart, Data Plow Diagram does not supply detailed description of the modules but graphically describes a systemQs data and how the data interact with the system. A data Oow diagram has the purpose of clarifying system re$uirements and identifying major transformation that will become programs in system design. Bt is the starting point of the system design phase that functionally decomposes the re$uirements speci#cations down to the lowest level of details. A data Oow diagram consists of a series of bubbles joined by lines. The bubbles represent data process and the line represents data Oow in the system. DataOow diagrams are also known as bubble chart. Bt consists of a series of bubbles joined by lines. The bubbles represent data transformation and the lines represent the dataOow in the system.
Data Plow diagram represents the Oow of data rather than how they are process. So it doesnQt depend on hardware, software and data structure and #le organi:ation.
An arro# identifies the data flo# in motion. It is a pipeline through #hich information is flo#n like the rectangle in the flo#chart. A circle stands for process that converts data into information. An open" ended bo/ represents a data store" data at rest or a temporary repository of data. A s)uare defines a source or destination of system data.

A data Oow moves data between processes or between processes and data stores. As such, it represents a data value at some point within a computation and an intermediate value within a computation if the Oow is internal to the diagram. This value is not changed. The names of input and output Oows can indicate their roles in the computation or the type of the value they move. Data names are preferably nouns. The name of a typical piece of data, the data aspect, is written alongside the arrow. CONTROL FLO/
A control Oow is a signal that carries out a command or indicates that something has occurred. A control Oows occurs at a discrete point in time. The arrow indicates the direction of the control Oow. The name of the event is written beside the arrow. 2ontrol Oows can correspond to messages in 22Ds or events in STDs. 3owever because they duplicate information in the DPD, use them sparingly. RULES USED FOR *ONSTRU*TIN+ A DFD
"rocess should be named and numbered for easy references. +ach name should be representative of the process. The direction of Oow is from top to bottom and from left to right. That is data Oow should be from source and destination. hen a process is e!ploded into lower level details, they are numbered. The name of the data stores, sources and destinations are written in capital letters. "rocess and data Oow names have the #rst letter of each word capitali:ed. The DPD is particularly designed to aid communication. Bf it contains do:ens of process and data stores it
gets too unwieldy. The rule of the thumb is to e!plode the DPD into a functional level

ENTIT' RELATIONS*IP DIA)RAM
An entity4relationship diagram is a graphical depiction of organi:ational system elements and the association among the elements. +4* diagrams can help de#ne system bounda ries. The entity relationship diagram is also called as +*D or +4*D is a network model that describes the stored data layout of the system at the high level of abstraction. The +*D is an eective modeling tool for communicating with D
=bject type 9 Bt a rectangular bo! and it represents a collection or a set of objects.
•
*elationships , =bjects are connected to one another by relationships. A relationship represents the set of connections between the objects and it is represented by a diamond bo!.
•
Associative =bject Type Bndicators, Bt is a special notation in the +*D. This represents something that functions both as an object and a relationship. Super type ) Subtype Bndicators, The super type ) subtype indicators consists of object type and one or more subcategories, connected by a relationship.
ENTITIES AND ENTIT' SET
An entity is an object that e!ists and is distinguishable from other objects. Por instance, pair with S.B.&. /40;4K8-9 is an entity, as he can be uni$uely identi#ed as one particular person in the universe. An entity may be concrete 5a person or a book, for e!ample7 or abstract 5like a holiday or a concept7. An entity set is a set of entities of the same type 5e.g., all persons having an account at a bank7. +ntity sets need not be disjoint. An entity is represented by a set of attributes.
OPTIONAL RELATIONS*IP
Bt means that there may be instances of the #rst entity, which are not associated with any instance of the second entity. Por e!ample, employee4spouse relationship has to be optional because there could be unmarried employees. Bt is not correct to make the relationship mandatory. NORMALIATION
Bn relational database design, the process of organi:ing data to minimi:e redundancy is called &=*AGB6ATB=&. &ormali:ation usually involves dividing a database into two or more table and de#ning relationships between tables. The objective is to isolate data so that addition, deletion and modi#cation of a #eld can be made in just one table and then propagated through the rest of the database via de#ned relationships. There are #ve normal forms, each with increasing levels of normali:ation •
PB*ST &=*AG P=* 50&P7' +very cell in the table must have only one value 5i.e.,7 it should not have multiple values.
•
S+2=&D &=*AG P=* 5;&P7' All non4key attributes must be fully functional dependent on the primary key and not just the part of the key.
•
T3B*D &=*AG P=* 5K&P7' The database must be in second normal form and non4prime attribute should be transitively dependent on the primary key.
•
P=1*T3 &=*AG P=* 58&P7' Bt deals with multiple values dependencies.
•
PBPT3 &=*AG P=* 5-&P7' Bt deals with joined dependencies. Database is generally normali:ed up to K&P, as every cell in the table has only one value i.e. it does not have multiple values. All non4key attributes are fully dependent on the primary key and not just the part of the key and non4prime attribute is transitively dependent on
<3= DATA4ASE DESI+N
A database is a collection of interrelated data stored #ith minimum redundancy to serve many users )uickly and efficiently. The general objective of database design is to make the data access easy" ine/pensive and fle/ible to the user. Sets of fundamental design concepts are evolved over the past here decades. Although the degree of interest in each concept has varied over the years" each has stood the test of time. 1undamental design concepts provide the necessary frame#ork for Pgetting it right>" *esign is defining a model of the ne# system and continues by converting this model to a ne# system. The method is used to convert the model of the proposed system into computer speci#cation. Data models are converted to a database and processes and Oow to user procedures and computer programs. This new system may be built by a fresh or by changing the e!isting system. The detailed design starts with three activities, database design, user design and program design.

;,2 INPUT DESI)N
The input re$uirement for the system involves the process of converting the user oriented inputs to a computer format. 2ollecting the input data for a system is an e!pensive one. The input design should be validated such that it is free from erroneous data. The user interface re$uirements are important input design, which
helps users how to access or enter data in the input form. The data is validated by the system if they are any errors the system will give error messages, which is easy to understand by the users. 1S+*4BD' The users can log on to the system with the user4id, which helps the system to identify the users. "ASS=*D' This is a facility that along with the user4id allows a user to log on to the system. A source document diers from a turnaround document in that the former contains data that change the status of a resource while the latter is a mobile readable needed. Social network re$uirement satisfaction throughput is the number of error4free transactions entered during a speci#ed time period. There are several activities involved in input processes. They are DATA CONTROL
There are several reasons why an eective design should control the $uantity of data for input. The input phase of computing can be slow process that can take many times longer than the time needed by computers to carry out their tasks.
Data eri#cation is intended to #nd errors. The data is veri#ed after the users had entered the input data. DATA 1ALIDATION
Bnput data are validated to minimi:e error in data entry. 2omputer input procedures are designed to detect errors in the data at a lower level of detail which is beyond the capacity of the control procedures. These are combined with the design of their input process itself. 7ASIC PRINCIPLES •

;,+ OUTPUT DESI)N
=utput is the most important and direct sources of information to the user. +%cient and intelligent output design improves the systems relationship with the user thus helping in the process of the decision U making. Audio information transactions are generally referred to the results and the information that are in the activities of operational information shared in to the cloud. The output design consists of the two stages namely the output de#nition stage and the output speci#cation stage. A $uality output is one, which meets the re$uirements of the end user and presents the information clearly. Bn any system results of processing are communicated to the users and to other mo through outputs. Bn the output design it is determined how the information is to be displayed for immediate need and also the soft
copy. =utputs Activities computers are
re$uired primarily to communicate the results of processing to the users. They are also used to provide a permanent copy of these results for later consultation. Bt is the most important and direct source information to the user. +%cient and intelligent output design improves the systemQs relationship the user and helps in decision4making. Bt is necessary that the output reports be compatible format with the automatically. The output has been designed in mind. =utput design is the
basis by which many users eva luate the useful ness of the syste m.
The output
forms used in this mobile applica tion are re$uired for $uery response and reports. The emphasis is re$uired for producing the hard copy of the information re$uested or displaying the output on a mobile screen.
<, S'STEM TESTIN) AND IMPLEMENTATION
<,. S'STEM TESTIN)
Testing is vital to the success of the system. System testing makes a logical assumption, if all the parts of the system are correctH the goal will be successfully achieved. System testing is the stage of implementation that we aimed at assuring that the system works accurately and e%ciently before live operation commences. PURPOSE OF TESTIN)
A failure occurs when a program misbehaves. Thus a failure is the statistical property of a system in e!ecution. A fault e!ists in program code. A fault may cause of failure. Bf there is a no fault in the program then the program cannot fail. Software testing is a critical element of software $uality assurance and represents the ultimate review of speci#cation, design and coding. The user tests the developed system and changes are made according to their needs. The testing phase involves the testing of developed system using various kinds of data. The objectives of testing are the process of e!ecuting the program with the intention of #nding an error. •
A good test is one that has a high probability of #nding an as4yet4 undiscovered error.
•
A successful test is that which uncovers as4yet4undiscovered error. Therefore the most useful approach and practical approach is aid the
understanding that testing is the process of e!ecuting a program e!plicit indention of #nding errors that is making the program fall.

Content &rovider Testing
UNIT TESTIN)
1nit testing focuses veri#cation eort on the smallest unit of software design the module. The relative comple!ity of the tests and the errors detected as a result is limited by the constrained scope established for unit testing. The unit test is always white bo! oriented and the step can be conducted in parallel for multiple modules. According to unit testing the router system is error free. 1nit testing has been performed for all the form modules. The synta! and logical errors has been corrected then and there. The output has been tested with the manual. INTE)RATION TESTIN)
Bntegration testing is a systematic techni$ue for construction the program structure while the same time conducting tests to uncover errors associated with interfacing. The objective is to take unit tested modules and build a program structure that has been dictated by design. Bntegration Testing is performed for the modules like Service. 2orrection is di%cult because the isolation of causes is complicated by the vast e!panse of the entire program once there errors are corrected new ones appear and the process continues and have endless loop. According to the integration testing in the intrusion detection system all the modules are integrated and tested for its accuracy. 1ALIDATION TESTIN)
alidation can be de#ned in many ways.
System testing is the testing of the integrated black bo! application, against the applicationQs re$uirements during the construction phase. The purpose of
system testing is it identi#es band correct errors in candidate system. System testing is the stage of implementation which aims at ensuring that the system accurately and e%ciently before the actual operation comments. Bn the project the system testing is implemented for checking the security re$uirements like prohibiting from unauthori:ed access, failures during invalid conditio ns and the operational availability re$uirements.

system. System testing is actually a series of dierent tests whose primary purpose is to fully e!oreic the computer4based system. Although each test has a dierent purpose, all work to verify that all system elements have been properly integrated and perform allocated functions. During testing B tried to make sure that the product does e!actly what is supposed to do. Testing is the #nal veri#cation and validation activity within the organi:ation itself. Bn the testing stage, B try to achieve the following goalsH to a%rm the $uality of the product, to #nd and eliminate any residual errors from previous stages, to validate the software as a solution to the original problem, to demonstrate the presence of all speci#ed functionality in the product, to estimate the operational reliability of the system. During testing the major activities are concentrated on the e!amination and modi#cation of the source code.
<,2, S'STEM IMPLEMENTATION
System implementation is considered to be the most crucial stage in achieving a successful system because if it is not properly planned and controlled, it can because chaos. Bmplementation is the stage when theoretical design has been converted into a working system. Bt involves the careful planning, investigation of the current system and its constraints on implementation, design of methods to achieve changeover, training of stas in the changeover procedures and evaluation of changeover methods.
System implementation discusses about the implementation plan, system testing, how to take backups. Bt also involves user training for minimi:ing resistance to change and giving the system a chance to prove its worth. A software application in general is implemented after navigating the complete life cycle method of a project. arious life cycle processes like re$uirement analysis, design phase, testing and veri#cation, #nally followed by the implementation phase results in a successful project management. As the software is to be implemented in a high standard industrial sector, various factors such as application environment, user management, security, reliability and #nally performance are taken as key factors throughout the design phase. These factors are analy:ed step by step and the positive and negat ive outcomes are noted before the #nal implementation. Security and authentication is maintained in both user level as well as the management level. The data is stored in the server with SMG Server, which is highly secured in a web serverH the user level security is managed with the help of password options and sessions, which #nally ensures that all the transactions are made securely. The applicationQs validations are taken into account of the entry levels available in various modules. "ossible restrictions like number formatting, date formatting and con#rmations for both save and update options ensure the correct data to be fed into the database.
=,FURT*ER SCOPE OF T*E PRO0ECT
The system is highly Oe!ible, so that the maintenance and further amendments based on the changing environment and re$uirements can be made easily. Any changes that may lead to the system failures are prevented with security measures. Bt can be further devel oped to include more operational and analysis, as changes are re$uired in the system to adapt to the e!ternal development. Purther enhancement can be made to the system at any later point. 2oding procedures can be modi#ed according to the needs of the user. The future scope of our project is that it can be implemented over the Bnternet to administrator and monitor systems connected to www. e propose more to introduce authentication and security for controlling and monitoring over the Bnternet. Purther additions can be made to this project. Time constraint prohibited me from pursuing them. A viewer is provided on the cellular phone that enables the user to see and manipulate the desktop of various remote systems such as S indows, acintosh, and 1&BN. The system to be accessed must be running the client program and it must be attached to a network. This project is designed with the future in mind. Due care has been taken to assimilate the needs for future development. The software is constructed along the lines suggested by the users. A new tool creation is under process which will have the drag and drop options which help the users generate reports by themselves and it is considered to be a major enhancement for the application.
