2.0 Introduction2.1 Why you choose this project .

Selecting a company to this project was very difficult for me,because I had to concern about lot of things and lot of areas.To choose this company I have had several good reasons such as,

- It covers the all parts

- It is easy to develop

- It gave me a big knowledge

So when I concerned about these three reasons, this company

was the most suitable one because I believe that I could gain

a big knowledge as well as I could get a big experience.

2.2 Background of the project

This company have a system already, but it’s too complex to

use and very old system, so we giving them a newer and easier

system which is fulfilling their requirements. First of all I

must say my client was “Prashakthi” Company. Company wants to

take all the deals and transactions to one system which can

easily manage. When I was analysing this company’s system we

came across eight major classes and their attributes which

cover all the customer requirements. There are,

1. Chemical factory end

2. Labour’s end

3. Office staff

4. Service stations end

11

5. Customers

6. Office branches

7. Departments

8. Chemical dealers

2.3 Constraints and limitations

The current software running on this company was windows based

software. Nowadays windows based software are not using,

because it’s very hard to use and manage. Most of the

companies are having web based software, with a small network.

In a network based company we should have functionality to

access to the system place where we are , also every data

base must be update automatically every day, that means it

should be a web base system .Current system is not that much

flexible. The worst problem is we can’t expand their

functionalities in this system. Also we have system problems

such as,

- Can’t update some data base functionalities

- Not included all network functionalities

- System updating problems

- Data and information managing problems

- Administrator accessing problems

12

This company have a lot of issues like which I have mentioned

above and it had a lot of limitations inside this software. So

I hope to give a good solution including all the

functionalities such as,

- Can access from anywhere (web site)

- Good network solution

- Updating database

- Can expand and add functionalities when needed

- Better Internet connection

- Highly manage floor system (Properly divide into separate

departments)

- Data back-up system

3.0 Existing hardware and software in the company3.1 Software

This company uses very primary software; it consists of several windows applications and small data base. Those windows applications based on C# language and it has written using “Visual studio”. Here are few screen shots of that existing software of my client uses currently.

The back end of this software, the data base of this software

has built on using “SQL server management” with simple SQL

statement.

3.2 Hardware

My client’s current using software and network are not

required very much to perform hardware components. In their

system we can categorize hardware components under three

categories ,

1. Core i3 PC - for each office ( daily use)

2. Core i5 PC - for as server

3. Network devices;

- routers

- switches

- network cables

- Servers

4.0 Company issues 4.1 Database issues

Security Updates are not applied.

The most common critical issue I have found was that Windows

Updates have not been applied regularly. Not only that but

also identified the current issues with health (specific

updates missing). But when considered through a series of

operational interview questions, identified that there was

a risk because there was no comprehensive patching policy.

SQL was running under an administrative account.

21

I have found that, while installing SQL Server, an ‘administrator’ or equivalent service account has been selected. This lead to an unwanted elevation of privilege security risk. Identified that all instances of SQL Server which were running under such privileged accounts.

Database integrity checks which are not scheduled

Many times, I found that the DBCC CHECKDB command has never

been executed, or was not executed on a regular basis. This

can very well fail on alerting us to impending catastrophic

failure of the database due to corruption issues. I identified

databases for which CHECKDB has either never run or had not

run at least once in the last week. It has been recommended

that the CHECKDB will be scheduled on a monthly basis and on-

demand for significant events such as unexpected shutdown /

failover of the server.

SQL Server has not been updated to the current service pack

Another very common issue is that SQL instances are not

updated with the current service pack. Not only this is

important from a supportability point of view, but it is also

important to receive the latest security, performance and

stability fixes. I identified all instances where have

installed older service packs. The onsite PFE in the case of

the SQL RAP offering will also advise you through a knowledge

transfer exercise on the importance of testing this update

prior to application.

Data Back-up system

4.2 Software Issues

- We aren't going to get the product support we need when a

problem occurs.

- We aren't going to get upgrade information or special

(legal) deals that might come in handy.

- Without genuine software, we can't be sure what you get

won't be infected with viruses or tainted by broken or

incomplete code.

- We likely aren't managing our client software inventory

very efficiently, especially if we mix legal with pirated

software and can't account for which is which, or whether

employees have only the software they need or use.

- We'll have to do some creative accounting for tax

purposes if, say, we bought 10 new PCs in the past year

and only one set of software applications.

4.3 Instant update for all branches

- When we’ll update our client system it’s getting late to

updates other branches, sometime it’ll not happen and

system will down for some hours.

- Every database not update daily and also the system not

capable update the system when a transition done.

4.4 Network issue

23

- “Janitorial service” head office network not connect with

“chemical factory” network, both work as isolated

networks.

- Issue with network privileges.

- Not maintain very well.

Existing Network (Outlook)

Figure 10

This is the basic outlook of the existing network. There aretwo routers belongs to each of the site, they are “Janitorialservice” site and “chemical factory “site .Each site is havingspecific server and specific switch, all the accessing devicesare connected to the switch. This network consists with allcisco devices such as,

- Cisco 2811 Router- Cisco 2950-24 Switches- Cisco Servers

24

Major problems with this network are; this network doesn’t have any Fire wall and Data back–up system also using resources unnessasarly.

5.0 Data modeling5.1 Exciting data model

Figure 11

This “Entity diagram” is company’s existing data model. It’s a

brief data model of their existing system, which shows only

the major points of their system, because before introducing

25

proposed data model have to get a small idea about the

company.

Whole network is divided into two parts for the easiness ofarchitect and configure. Main branch controls the wholesystem. It is connected to service provider and it distributesthe connection. Main branch has the core router, Databaseserver and Back up storage. Chemical factory catches theconnection through a Border router and it distributes theconnection to their apartment. This network Architecture stopswasting money because of their existing systems that used intwo separate servers. And these architects increase the speedof the connection.

When we selecting network devices ,we select big devices suchas Core Router – CRS-X not expected for the current system butwhen we calculate the data traffic and so on we need that kindof router after two ,three years later but it’s not easy toreplace another one.so being on that purpose we select most ofthe network devices.

6.5 Software Solution

6.5.1 Depth of the software

43

For both these companies had same problem. They had problemwith maintain some data and filtering some data. So as asolution we come up with an idea, which is, divide these twocompanies in to separate division and gave a windows baseapplication for each department. But the good thing is thoseall applications properly connect with each other. It will notshowing to the end user. This software is not hard to use theonly thing is understand the software.

The main advantage of this application is you can login toyour system even in at home ,we gave a separate id and thepassword for each user. Also for the Head for this company cancheck out the stores, production etc through the web site. Webuilt a separate website for this also

Follow I show some screen shots in propose system

6.5.3 Data Base solution

- Data base we are updating data base from each night.

-We are using data back –up system

-Implementing security system

-Using updating version (using original software’s)

6.5.4 Policy Changes

- We are giving ID card for each and every member with specific number

- Every employee permanent after two month- No one allow to download /installing applications in pc’s

46

- Each password must change after two months

6.6 Maintains team and parallel run

For an each project we have separate group. Each group consistwith five members .It consist of like this ,one seniorDeveloper ,one Tec-lead and rest of the people are developers.We are conducting a special meeting before starting projectand divide the whole project under few categories. After thatwe select a person for each category. This team handles theall software parts and network side covering by specificnetworking group.

When we start the project, after every month we release anupdate for the company to see how it’s working and what issueswe get with the new software are. That method not only help tous it also a help to company to getting use to new system andbe familiar with that. On the other hand there is a specialreason for releasing an update like that, because if we goingto release our whole project at once it will take to finishthe project may be two or three years.so at that time theirexpects may be change. So to avoid that problem we arereleasing an update monthly.

7.0 conclution- This new system faster than the old system- This system protect the data in company- Make easy to work- Network will connect each and every branch without any

problem
