SYSTEM STUDY AND ANALISYS
SYSTEM ANALYSIS )"stem anal"sis is a process of gathering and interpreting facts! diagnosing problems and the information to recommend improvements on the s"stem. +t is a problem solving activit" that re#uires intensive communication between the s"stem users and s"stem developers. )"stem anal"sis or stud" is an important phase of an" s"stem development process. The s"stem is studied to the minutest detail and anal"zed. The s"stem anal"st pla"s the role of the interrogator and dwells deep into the working of the present s"stem. The s"stem is viewed as a whole and the input to the s"stem are identified. The outputs from the organizations are traced to the various processes. )"stem anal"sis is concerned with becoming aware of the problem! identif"ing the relevant and decisional variables! anal"zing and s"nthesizing the various factors and determining an optimal or at least a satisfactor" solution or program of action. A detailed stud" of the process must be made b" various techni#ues like interviews! #uestionnaires etc. The data collected b" these sources must be scrutinized to arrive to a conclusion. The conclusion is an understanding of how the s"stem functions. This s"stem is called the e$isting s"stem. ,ow the e$isting s"stem is subjected to close stud" and problem areas are identified. The designer now functions as a problem solver and tries to sort out the difficulties that the enterprise faces. The solutions are given as proposals. The proposal is then weighed with the e$isting s"stem anal"ticall" and the best one is selected. The proposal is presented to the user for an endorsement b" the user. The proposal is reviewed on user re#uest and suitable changes are made. This is loop that ends as soon as the user is satisfied with proposal.

SYSTEM DESIGN
3.1 INTRODUCTION 7esign is the first step into the development phase for an" engineered product or s"stem. 7esign is a creative process. A good design is the ke" to effective s"stem. The term “design@ is defined as “the process of appl"ing various techni#ues and principles for the purpose of defining a process or a s"stem in sufficient detail to permit its ph"sical realization@. +t ma" be defined as a process of appl"ing various techni#ues and principles for the purpose of defining a device! a process or a s"stem in sufficient detail to permit its ph"sical realization. )oftware design sits at the technical kernel of the software engineering process and is applied regardless of the development paradigm that is used. The s"stem design develops the architectural detail re#uired to build a s"stem or product. As in the case of an" s"stematic approach! this software too has undergone the best possible design phase fine tuning all efficienc"! performance and accurac" levels. The design phase is a transition from a user oriented document to a document to the programmers or database personnel. )"stem design goes through two phases of development1 6ogical and *h"sical 7esign. LOGICAL DESIGN: The logical flow of a s"stem and define the boundaries of a s"stem. +t includes the following steps1 • 0eviews the current ph"sical s"stem A its data flows! file content! volumes ! fre#uencies etc.

PHYSICAL DESIGN: *h"sical s"stem produces the working s"stems b" define the design specifications that tell the programmers e$actl" what the candidate s"stem must do. +t includes the following steps. • 7esign the ph"sical s"stem. • )pecif" input and output media. • 7esign the database and specif" backup procedures. • 7esign ph"sical information flow through the s"stem and a ph"sical design 3alk through. • *lan s"stem implementation. • *repare a conversion schedule and target date. • 7etermine training procedures! courses and timetable. • 7evise a test and implementation plan and specif" an" new hardware4software. • -pdate benefits ! costs ! conversion date and s"stem constraints Desi !"S#e$i%i$&'i(! &$'i)i'ies: • • • • • • %oncept formulation. *roblem understanding. <igh level re#uirements proposals. ;easibilit" stud". 0e#uirements engineering.

MODULE DESIGN A*+i! The Administrator logs in using the admin login. +n this module two operations are done. 7uring login the 6ogin and *assword is verified with that in the database INPUT DESIGN The design of input focuses on controlling the amount of input re#uired! controlling the errors! avoiding dela"! avoiding e$tra steps and keeping the process simple. The input C

is designed in such a wa" so that it provides securit" and ease of use with retaining the privac". +nput 7esign considered the following things1 o 3hat data should be given as input= o <ow the data should be arranged or coded= o The dialog to guide the operating personnel in providing input. o ethods for preparing input validations and steps to follow when error occur. OB,ECTIVES +nput 7esign is the process of converting a user.oriented description of the input into a computer.based s"stem. This design is important to avoid errors in the data input process and show the correct direction to the management for getting correct information from the computerized s"stem. +t is achieved b" creating user.friendl" screens for the data entr" to handle large volume of data. The goal of designing input is to make data entr" easier and to be free from errors. The data entr" screen is designed in such a wa" that all the data manipulates can be performed. +t also provides record viewing facilities. 3hen the data is entered it will check for its validit". 7ata can be entered with the help of screens. Appropriate messages are provided as when needed so that the user will not be in a maize of instant. Thus the objective of input design is to create an input la"out that is eas" to follow OUTPUT DESIGN A #ualit" output is one! which meets the re#uirements of the end user and presents the information clearl". +n output design it is determined how the information is to be displaced for immediate need and also the hard cop" output. +t is the most important and direct source information to the user. /fficient and intelligent output design improves the s"stem8s relationship to help user decision.making. 7esigning computer output should proceed in an organized! well thought out mannerD the right output must be developed while ensuring that each output element is designed so that people will find the s"stem can use easil" and effectivel". 3hen anal"sis design computer output! the" should 1  +dentif" the specific output that is needed to meet the re#uirements.  )elect methods for presenting information.  %reate document! report! or other formats that contain information produced b" the s"stem. 3.3 DATABASE DESIGN

E

A database is an organized mechanism that has the capabilit" of storing information through which a user can retrieve stored information in an effective and efficient manner. The data is the purpose of an" database and must be protected. The database design is a two level process. +n the first step! user re#uirements are gathered together and a database is designed which will meet these re#uirements as clearl" as possible. This step is called +nformation 6evel 7esign and it is taken independent of an" individual 7B ). +n the second step! this +nformation level design is transferred into a design for the specific 7B ) that will be used to implement the s"stem in #uestion. This step is called *h"sical 6evel 7esign! concerned with the characteristics of the specific 7B ) that will be used. A database design runs parallel with the s"stem design. The organization of the data in the database is aimed to achieve the following two major objectives.  7ata +ntegrit"  7ata independence ,ormalization is the process of decomposing the attributes in an application! which results in a set of tables with ver" simple structure. The purpose of normalization is to make tables as simple as possible. ,ormalization is carried out in this s"stem for the following reasons. • • • • To structure the data so that there is no repetition of data ! this helps in saving. To permit simple retrieval of data in response to #uer" and report re#uest. To simplif" the maintenance of the data through updates! insertions! deletions. To reduce the need to restructure or reorganize data which new application re#uirements arise.

RELATIONAL DATABASE MANAGEMENT SYSTEM -RDBMS.: A relational model represents the database as a collection of relations. /ach relation resembles a table of values or file of records. +n formal relational model terminolog"! a row is called a tuple! a column header is called an attribute and the table is called a relation. A relational database consists of a collection of tables! each of which is assigned a uni#ue name. A row in a tale represents a set of related values. RELATIONS/ DOMAINS 0 ATTRIBUTES: A table is a relation. The rows in a table are called tuples. A tuple is an ordered set of n elements. %olumns are referred to as attributes. 0elationships have been set between ever" table in the database. This ensures both 0eferential and /ntit" 0elationship +ntegrit". A domain 7 is a set of atomic values. A common method of specif"ing a domain is to specif" a data t"pe from which the data values forming the domain are drawn. +t is also useful to specif" a name for the domain to help in interpreting its values. /ver" value in a relation is atomic! that is not decomposable. RELATIONSHIPS: F

Table relationships are established using Ge". The two main ke"s of prime importance are *rimar" Ge" H ;oreign Ge". /ntit" +ntegrit" and 0eferential +ntegrit" 0elationships can be established with these ke"s./ntit" +ntegrit" enforces that no *rimar" Ge" can have null values.0eferential +ntegrit" enforces that no *rimar" Ge" can have null values. 0eferential +ntegrit" for each distinct ;oreign Ge" value! there must e$ist a matching *rimar" Ge" value in the same domain. Other ke" are )uper Ge" and %andidate Ge"s. 0elationships have been set between ever" table in the database. This ensures both 0eferential and /ntit" 0elationship +ntegrit". NORMALI1ATION: As the name implies! it denoted putting things in the normal form. The application developer via normalization tries to achieve a sensible organization of data into proper tables and columns and where names can be easil" correlated to the data b" the user. ,ormalization eliminates repeating groups at data and thereb" avoids data redundanc" which proves to be a great burden on the computer resources. These includes1  ,ormalize the data.  %hoose proper names for the tables and columns.  %hoose the proper name for the data. Fi2s' N(2+&3 F(2+1 The ;irst ,ormal ;orm states that the domain of an attribute must include onl" atomic values and that the value of an" attribute in a tuple must be a single value from the domain of that attribute. +n other words 2,; disallows “relations within relations@ or “relations as attribute values within tuples@. The onl" attribute values permitted b" 2,; are single atomic or indivisible values. The first step is to put the data into ;irst ,ormal ;orm. This can be donor b" moving data into separate tables where the data is of similar t"pe in each table. /ach table is given a *rimar" Ge" or ;oreign Ge" as per re#uirement of the project. +n this we form new relations for each nonatomic attribute or nested relation. This eliminated repeating groups of data. A relation is said to be in first normal form if onl" if it satisfies the constraints that contain the primar" ke" onl". Se$(!* N(2+&3 F(2+1 According to )econd ,ormal ;orm! ;or relations where primar" ke" contains multiple attributes! no nonke" attribute should be functionall" dependent on a part of the primar" ke". +n this we decompose and setup a new relation for each partial ke" with its dependent attributes. ake sure to keep a relation with the original primar" ke" and an" attributes

I

that are full" functionall" dependent on it. This step helps in taking out data that is onl" dependant on apart of the ke". A relation is said to be in second normal form if and onl" if it satisfies all the first normal form conditions for the primar" ke" and ever" non.primar" ke" attributes of the relation is full" dependent on its primar" ke" alone. T4i2* N(2+&3 F(2+1 According to Third ,ormal ;orm! 0elation should not have a nonke" attribute functionall" determined b" another nonke" attribute or b" a set of nonke" attributes. That is! there should be no transitive dependenc" on the primar" ke". +n this we decompose and set up relation that includes the nonke" attributes that functionall" determines other nonke" attributes. This step is taken to get rid of an"thing that does not depend entirel" on the *rimar" Ge". A relation is said to be in third normal form if onl" if it is in second normal form and more over the non ke" attributes of the relation should not be depend on other non ke" attribute.

?.2 SYSTEM IMPLEMENTATION AND TESTING
+mplementation is the stage of the project where the theoretical design is turned into a working s"stem. +t can be considered to be the most crucial stage in achieving a successful new s"stem gaining the users confidence that the new s"stem will work and will be effective and accurate. +t is primaril" concerned with user training and documentation. %onversion usuall" takes place about the same time the user is being trained or later. +mplementation simpl" means convening a new s"stem design into operation! which is the process of converting a new revised s"stem design into an operational one. ?.2.1. SYSTEM TESTING )oftware Testing is the process of e$ecuting software in a controlled manner! in order to answer the #uestion . 7oes the software behave as specified=. )oftware testing is often used in association with the terms verification and validation. &alidation is the checking or testing of items! includes software! for conformance and consistenc" with an associated specification. )oftware testing is just one kind of verification! which also uses techni#ues such as reviews! anal"sis! inspections! and walkthroughs. &alidation is the process of checking that what has been specified is what the user actuall" wanted. &alidation &erification : Are we doing the right job= : Are we doing the job right=

5?

)oftware testing should not be confused with debugging. 7ebugging is the process of anal"zing and localizing bugs when software does not behave as e$pected. Although the identification of some bugs will be obvious from pla"ing with the software! a methodical approach to software testing is a much more thorough means for identif"ing bugs. 7ebugging is therefore an activit" which supports testing! but cannot replace testing. Other activities which are often associated with software testing are static anal"sis and d"namic anal"sis. )tatic anal"sis investigates the source code of software! looking for problems and gathering metrics without actuall" e$ecuting the code. 7"namic anal"sis looks at the behavior of software while it is e$ecuting! to provide information such as e$ecution traces! timing profiles! and test coverage information. Testing is a set of activit" that can be planned in advanced and conducted s"stematicall". Testing begins at the module level and work towards the integration of entire computers based s"stem. ,othing is complete without testing! as it vital success of the s"stem testing objectives! there are several rules that can serve as testing objectives. The" are Testing is a process of e$ecuting a program with the intend of finding an error.A good test case is one that has high possibilit" of finding an undiscovered error.A successful test is one that uncovers an undiscovered error. +f a testing is conducted successfull" according to the objectives as stated above! it would uncovered errors in the software also testing demonstrate that the software function appear to be working according to the specification! that performance re#uirement appear to have been met. There are three wa"s to test program. • ;or correctness • ;or implementation efficienc" • ;or computational comple$it" Test for correctness are supposed to verif" that a program does e$actl" what it was designed to do. This is much more difficult than it ma" at first appear! especiall" for large programs.

TEST PLAN
A test plan implies a series of desired course of action to be followed in accomplishing various testing methods. The Test *lan acts as a blue print for the action that is to be followed. The software engineers create a computer program! its documentation and related data structures. The software developers is alwa"s responsible for testing the individual units of the programs! ensuring that each performs the function for which it was designed. There is an independent test group '+T9( which is to remove the inherent problems associated with letting the builder to test the thing that has been built. The specific objectives of testing should be stated in measurable terms. )o that the mean time 5B

to failure! the cost to find and fi$ the defects! remaining defect densit" or fre#uenc" of occurrence and test work.hours per regression test all should be stated within the test plan. The levels of testing include1 • • • • -nit testing +ntegration Testing 7ata validation Testing Output Testing

UNIT TESTING -nit testing focuses verification effort on the smallest unit of software design A the software component or module. -sing the component level design description as a guide! important control paths are tested to uncover errors within the boundar" of the module. The relative comple$it" of tests and uncovered scope established for unit testing. The unit testing is white.bo$ oriented! and step can be conducted in parallel for multiple components. The modular interface is tested to ensure that information properl" flows into and out of the program unit under test. The local data structure is e$amined to ensure that data stored temporaril" maintains its integrit" during all steps in an algorithm8s e$ecution. Boundar" conditions are tested to ensure that all statements in a module have been e$ecuted at least once. ;inall"! all error handling paths are tested. Tests of data flow across a module interface are re#uired before an" other test is initiated. +f data do not enter and e$it properl"! all other tests are moot. )elective testing of e$ecution paths is an essential task during the unit test. 9ood design dictates that error conditions be anticipated and error handling paths set up to reroute or cleanl" terminate processing when an error does occur. Boundar" testing is the last task of unit testing step. )oftware often fails at its boundaries. -nit testing was done in )ell.)oft )"stem b" treating each module as separate entit" and testing each one of them with a wide spectrum of test inputs. )ome flaws in the internal logic of the modules were found and were rectified. INTEGRATION TESTING +ntegration testing is s"stematic techni#ue for constructing the program structure while at the same time conducting tests to uncover errors associated with interfacing. The objective is to take unit tested components and build a program structure that has been dictated b" design. The entire program is tested as whole. %orrection is difficult because isolation of causes is complicated b" vast e$panse of entire program. Once these errors are corrected! new ones appear and the process continues in a seemingl" endless loop. After unit testing in )ell.)oft )"stem all the modules were integrated to test for an" inconsistencies in the interfaces. oreover differences in program structures were removed and a uni#ue program structure was evolved.

5C

VALIDATION TESTING OR SYSTEM TESTING This is the final step in testing. +n this the entire s"stem was tested as a whole with all forms! code! modules and class modules. This form of testing is popularl" known as Black Bo$ testing or )"stem testing. Black Bo$ testing method focuses on the functional re#uirements of the software. That is! Black Bo$ testing enables the software engineer to derive sets of input conditions that will full" e$ercise all functional re#uirements for a program. Black Bo$ testing attempts to find errors in the following categoriesD incorrect or missing functions! interface errors! errors in data structures or e$ternal data access! performance errors and initialization errors and termination errors. OUTPUT TESTING OR USER ACCEPTANCE TESTING The s"stem considered is tested for user acceptanceD here it should satisf" the firm8s need. The software should keep in touch with perspective s"stemD user at the time of developing and making changes whenever re#uired. This done with respect to the following points  +nput )creen 7esigns!  Output )creen 7esigns!  Online message to guide the user and the like. The above testing is done taking various kinds of test data. *reparation of test data pla"s a vital role in the s"stem testing. After preparing the test data! the s"stem under stud" is tested using that test data. 3hile testing the s"stem b" which test data errors are again uncovered and corrected b" using above testing steps and corrections are also noted for future use. ?.3. TRAINING Once the s"stem is successfull" developed the ne$t important step is to ensure that the administrators are well trained to handle the s"stem. This is because the success of a s"stem invariabl" depends on how the" are operated and used. The implementation depends upon the right people being at the right place at the right time. /ducation involves creating the right atmosphere and motivating the user. The administrators are familiarized with the run procedures of the s"stem! working through the se#uence of activities on an ongoing basis. +mplementation is the state in the project where the theoretical design is turned into a working s"stem. B" this! the users get the confidence that the s"stem will work effectivel". The s"stem can be implemented onl" after through testing. The s"stems personnel check the feasibilit" of the s"stem. The actual data were inputted to the s"stem and the working of the s"stem was closel" monitored. The master option was selected from the main menu and the actual data were input through the

5E

corresponding input screens. The data movement was studied and found to be correct #ueries option was then selected and this contains various reports. -tilities provide various data needed for inventor" was input and the module was test run. )atisfactor" results were obtained. 0eports related to these processes were also successfull" generated. &arious input screen formats are listed in the appendi$. +mplementation walkthroughs ensure that the completed s"stem actuall" solves the original problem. This walkthrough occurs just before the s"stem goes into use! and it should include careful review of all manuals! training materials and s"stem documentation. Again! users! the anal"st and the members of the computer services staff ma" attend this meeting.
