INTRODUCTION


3/59



Intro%$ct"on:

The main aim of the project is the management of the database of the pharmaceutical

shop. This is done by creating a database of the available medicines in the shop. The

database is then connected to the main program by using interconnection of the Visual

asic program and the database already created.

&"cat"on:

This program can be used in any pharmaceutical shops having a database to maintain.

The soft!are used can generate reports" as per the user#s re$uirements. The soft!are

can print invoices" bills" receipts etc. %t can also maintain the record of supplies sent in

by the supplier

2.1 !eas"b"#"ty St$%y

( feasibility analysis involves a detailed assessment of the need" value and

practicality of a proposed enterprise" such as systems development. The process of

designing and implementing record )eeping systems has significant accountability

and resource implications for an organi*ation. +easibility analysis !ill help you ma)e

informed and transparent decisions at crucial points during the developmental process

to determine !hether it is operationally" economically and technically realistic to

proceed !ith a particular course of action.

Most feasibility studies are distinguished for both users and analysts. +irst" the

study often presupposes that !hen the feasibility document is being prepared" the

analyst is in a position to evaluate solutions. Second" most studies tend to overloo) the

confusion inherent in system development , the constraints and the assumed attitudes.

2.1.1 O&erat"ona# *eas"b"#"ty

People are inherently resistant to change" and computers have been )no!n to

facilitate change. (n estimate should be made of ho! strong a reaction the user staff

is li)ely to have to!ard the development of a computeri*ed system. %t is common

)no!ledge that computer installations have something to do !ith turnover" transfers"

retraining" and changes in employee job status. Therefore" it is understood that the

introduction of a candidate system re$uires special effort to educate" sell and train the

staff on ne! !ays of conducting business.

2.1.2 Techn"ca# *eas"b"#"ty

Technical feasibility centers around the e-isting computer system hard!are"

soft!are" etc./ and to !hat e-tend it can support the proposed addition. +or e-ample"

if the current computer is operating at 0 percent capacity , an arbitrary ceiling , then

running another application could overload the system or re$uire additional hard!are.

This involves financial considerations to accommodate technical enhancements. %f the

budget is a serious constraint" then the project is judged not feasible.

2.1.' Cost( )ene*"t ana#ys"s

3conomic analysis is the most fre$uently used method for evaluating the

effectiveness of a candidate system. More commonly )no!n as cost benefit analysis"

the procedure is to determine the benefits and savings that are e-pected from a

candidate system and compare them !ith costs. %f benefits over!eigh costs" then the

decision is made to design and implement the system. 4ther!ise" further justification

or alterations in the proposed system !ill have to be made if it is to have a chance of

being approved. This is an ongoing effort that improves in accuracy at each phase in

the system life cycle.

2.2 System na#ys"s

%t is the most creative and challenging phase of the system life cycle. The analysis

phase is used to design the logical model of the system !hereas the design phase is

used to design the physical model.

Many things are to be done in this phase .!e began the designing process by

identifying forms" reports and the other outputs the system !ill produce. Then the

specify data on each !ere pinpointed. !e s)etched the forms or say" the displays" as

e-pected to appear" on paper" so it serves as model for the project to began finally !e

design the form on computer display" using one of the automated system design tool"

that is V%S;(< (S%5 :..

(fter the forms !ere designed" the ne-t step !as to specify the data to be

inputted" calculated and stored individual data items and calculation procedure !ere

!ritten in detail. +ile structure such as paper files !ere selected the procedures !ere

!ritten so as ho! to process the data and procedures the output during the

programming phase. The documents !ere design ion the form of charts.

4utput design means !hat should be the format for presenting the results. %t

should be in most convenient and attractive format for the user. The input design deals

!ith !hat should be the input to the system and thus prepare the input format. +ile

design deals !ith ho! the data has to be stored on physical devices. Process design

includes the description of the procedure for carrying out operations on the given data.

4ne of the most impressive controls of Visual asic is the MS+le->rid control.

MS+le->rid control provides all the functionality for building spreadsheet applications"

The MS+le->rid control is an e-tremely useful tool for displaying data" but it

lac)s a basic compatibilityB the user cannot edit single cell.

There are t!o approaches to editing a grid#s cell. The first is to place a Te-to-

control on the form. 3ach time the user clic)s on a cell" the programs copies the contents

of the active cell to the Te-to- control and lets the user edit it. The second approach is a

bit more elegant" but it involves more comple- codingB if u place a Te-to- control !ith

the e-act same dimensions of the cell being edited right on top of the cell" the user gets

the impression of editing a cell directly on the grid.


40/59

To integrate the Te-to- control !ith the MS+le->rig control" use the

Ce##4"%th> Ce##5e"ght> Ce##To& and Ce##Le*t properties of the grid" !hich determine

Visual asic provides more of the actual code for a programmer than any other

non8visual programming language. This ma)es it a !idely used programming language

for visual applications.

%f you have ever programmed in the older (S%5 or other command line

programming language" then you !ill remember that the programmer had to !rite the

code for entire user interface. Today#s !indo!s" buttons" lists and other application

features such as menus !ere not built8in to the (S%5 programming language.

Programmers had to create the code for these features on their o!n.

(s much as 0L of a programmer#s time !as spent !riting code to create the user

interface to his applications the visual interface/. To eliminate this huge drain on a

programmer#s time" Microsoft had provided Visual asic !ith built8in capability to create

the user interface using nothing more than a mouse.

Visual asic is itself a !indo! application. Eou load and e-ecute the V system

just as you do other ?indo!s programsF !e use this running V program to create other

programs. V is just a tool" albeit an e-tremely po!erful tool" that programmers use to

!rite" test" and run !indo!s applications.

8"s$a# )as"c @8)A is an event driven programming language and associateddevelopment environment created by Microsoft. %n business programming" it has one of

the largest user bases.

%t is derived heavily from (S%5 and enables rapid application development

6(D/ of graphical user interface >;%/ applications" access to databases using D(4"

6D4" or (D4" and creation of (ctiveA controls and objects. ( programmer can put

together an application using the components provided !ith Visual asic itself.

This built8in interface creation capability has had the future benefit of

standardi*ing on the user interface to ?indo!s applications. Today" user can move from

one !indo! program to another and see the same basic interface tools to !or) !ith8

allo!ing them to concentrate solely on the uni$ue capabilities of the application.


45/59

The bottom line is that you can create an entire application shell the user

interface/ very $uic)ly and then spend most of your time !or)ing on the features" !hich

differentiate your application from its competitor.

Today you need much more than just a languageF you need a graphical

development tool that can !or) inside the !indo! system and applications that ta)e

advantage of all the graphical" multimedia" online and multiprocessor activities that

!indo!s offer.

Visual asic is such a tool. More than a language" Visual asic lets you generate

applications that interact !ith every aspect of today#s !indo!s operating systems.

( typical Session in Microsoft Visual asic :

Visual asic !as designed to be usable by all programmers" !hether novice or

e-pert. The language is designed to ma)e it easy to create simple >;% applications" but

also has the fle-ibility to develop fairly comple- applications as !ell. Programming in

V is a combination of visually arranging components on a form" specifying attributes

and actions of those components" and !riting additional lines of code for more

functionality. Since default attributes and actions are defined for the components" a

simple program can be created !ithout the programmer having to !rite many lines of

code. Performance problems !ere e-perienced by earlier versions" but !ith faster

computers and native code compilation this has become less of an issue.

(lthough programs can be compiled into native code e-ecutables from version

on!ards" they still re$uire the presence of runtime libraries of appro-imately 2 M in

si*e. This runtime is included by default in ?indo!s 2 and later" but for earlier

versions of ?indo!s it must be distributed together !ith the e-ecutable.

+orms are created using drag and drop techni$ues. ( tools palette is used to place

controls e.g." te-t bo-es" buttons" etc./ on the form !indo!/. 5ontrols have attributes

and event handlers associated !ith them. Default values are provided !hen the control is

created" but may be changed by the programmer. Many attribute values can be modified

during run time based on user actions or changes in the environment" providing a

dynamic application. +or e-ample" code can be inserted into the form resi*e event

handler to reposition a control so that it remains centered on the form" e-pands to fill up

the form" etc. y inserting code into the event handler for a )eypress in a te-t bo-" the

program can automatically translate the case of the te-t being entered" or even prevent

certain characters from being inserted.

( Visual asic application can consist of one or more !indo!s" or a single

!indo! that contains MD% child !indo!s" as provided by the operating system. Dialog

bo-es !ith less functionality e.g." no ma-imi*e7minimi*e control/ can be used to provide

pop8up capabilities. 5ontrols provide the basic functionality of the application" !hile

programmers can insert additional logic !ithin the appropriate event handlers. +or

e-ample" a drop8do!n combination bo- !ill automatically display its list and allo! the


47/59

user to select any element. (n event handler is called !hen an item is selected" !hich can

then e-ecute additional code created by the programmer to perform some action based on

The language is garbage collected using reference counting" has a large library of

components are included in the default project template" the programmer seldom needs to

specify additional libraries. ;nli)e many other programming languages" Visual asic is

generally not case sensitive" although it !ill transform )ey!ords into a standard case

&. Database 5onnectivityB 8

Some databases" such as Microsoft (ccess" store all the related database files in a

single global file called the database file. %nside the database" the individual

groups of records and fields are called tables. 4ther database systems" such as

dase" )eep trac) of a database#s data in multiple files. ?hen you use database

such as Microsoft (ccess" you must describe both the overall database and the

individual table name !ithin the database that the Data control is in use.

'. 5ontrolsB 8

5ontrols are tools on the Toolbo- !indo! that you place on a form to interact

!ith the user and control the program flo!. The controls can be self generated and

can be used again and again in the same application. (s you add controls to the

+orm !indo!" the properties !indo! updates to sho! the properties for the

currently selected control. The selected control is usually the control you last

placed on the form. Visual asic lets you see a control#s properties in the

from the properties !indo!#s drop8do!n list bo-.

(ccess is !idely used by small businesses and hobby programmers to create ad

hoc customi*ed systems for handling small tas)s. %ts ease of use and po!erful design

tools give the non8professional programmer a lot of po!er for little effort. Oo!ever" thisease of use can be misleading. This sort of developer is often an office !or)er !ith little

or no training in application or data design. ecause (ccess ma)es it possible even for

such developers to create usable systems" many are misled into thin)ing that the tool

itself is limited to such applications.

Some professional application developers use (ccess for rapid application

development" especially for the creation of prototypes and standalone applications that

serve as tools for on8the8road salesmen. (ccess does not scale !ell if data access is via a

net!or)" so applications that are used by more than a handful of people tend to rely on a

5lient8Server based solution such as 4racle" D2" Microsoft SI< Server" PostgreSI

alternative to the Net Database 3ngine. Q3arly versions of MSD3 and Microsoft

3-change Server actually use the Net engine to handle huge volumes of data and placed a

fa)e application layer for those applications on top of it.

De0e#o&ment

The programming language available in (ccess is" as in other products of the

Microsoft 4ffice suite" Microsoft Visual asic for (pplications. T!o database access

libraries of 54M components are providedB the legacy Data (ccess 4bjects D(4/" only

available !ith (ccess" and the ne! (ctiveA Data 4bjects (D4/.

Microsoft (ccess is easily applied to small projects but scales inefficiently to

large projects if applications are designed poorly.

(ll database $ueries" forms" and reports are stored in the database" and in )eeping

!ith the ideals of the relational model" there is no possibility of ma)ing a physically

structured hierarchy !ith them.

4ne design techni$ue is to divide an (ccess application bet!een data and

programs. 4ne database should contain only tables and relationships" !hile another

!ould have all programs" forms" reports and $ueries" and lin)s to the first database tables.

;nfortunately" (ccess allo!s no relative paths !hen lin)ing" so the development

environment should have the same path as the production environment (lthough you

can !rite your o!n dynamic8lin)er routine in V( that can search out a certain bac)8

end file by searching through the directory tree" if it cant find it in the current path/.

This techni$ue also allo!s the developer to divide the application among different

files" so some structure is possible.

The Microsoft Net Database 3ngine is a database engine on !hich several

Microsoft products !ere built. ( database engine is the underlying component of a

database" a collection of information stored on a computer in a systematic !ay. The first

version of Net !as developed in 1@@2" consisting of three modules !hich could be used to

manipulate a database.

N3T stands forJoint Engine Technology" sometimes being referred to asMicrosoft

JET Engine or simply Jet. Microsoft (ccess" Microsoft 3-change Server and Visual

asic use or have used Net as their underlying database engine. %t has since been

superseded" ho!ever" by Microsoft Des)top 3ngine MSD3/ and no longer e-ists as a

component of Microsoft Data (ccess 5omponents MD(5/. Net databases can be

upgraded or in Microsoft parlance" up8si*ed/ to an MSD3 database.


53/59

Sec$r"ty

(ccess to Net databases is done on a per user8level. The user information is )ept in

aseparate system database" and access is controlled on each object in the system for

instance by table or by $uery/. %n Net '" Microsoft implemented functionality that allo!ed

database administrators to set security via the SI< commands 563(T3" (DD" (6(CT763V493 commands.?hen Net 2 !as

released" security could also be set programmatically through D(4.

B$er"es

Iueries are the mechanisms that Net uses to retrieve data from the database. They

can be defined in Microsoft I3 Iuery y 3-ample/" through the Microsoft (ccess

SI< ?indo! or through (ccess asics Data (ccess 4bjects D(4/ language. These are

then converted to an SI< S3


54/59

Net passes the data retrieved for the $uery in a dynaset. This is a set of data that is

dynamically lin)ed bac) to the database. %nstead of having the $uery result stored in a

temporary table" !here the data cannot be updated directly by the user" the dynaset allo!s

the user to vie! and update the data contained in the dynaset. Thus" if a university

lecturer $ueried all students !ho received a distinction in their assignment and found an

error in that students record" they !ould only need to update the data in the dynaset"

!hich !ould automatically update the students database record !ithout the need for

them to send a specific update $uery after storing the $uery results in a temporary table.

Conc#$s"on an% !$t$re Sco&e

Detailed information gathering has to be done. ?ithout that the purpose

for using the soft!are !ont be satisfied properly.

Oo!ever it can give good profits in the long run.

%mplementing the soft!are re$uires change in the business practices.

3fficient organi*ation of all )no!ledge is the analysis company and easy

analysis access and retrieval of information is possible.

%n this project !e can also include (6 54D3 facility using the bar code

reader" !hich !ill detect the e-piry date and the other information about the

related medicines.

5ompany using this soft!are !ill al!ays be able to plan in future and

al!ays be a!are of their financial position in the mar)et.

%t leads to streamling of business processes.

The implementation and maintence costs run very high about 2 to & L of

the company#s revenue./
