12. IMPLEMENTATION
Implementation is the process of having systems personnel check out and put new equipment into use, train users, install the new application and construct any files of data needed to use it. This phase is less creative than system design. Depending on the size of the organization that will be involved in using the application and the risk involved in its use, systems developers may choose to test the operation in only one area of the firm with only one or two persons. Sometimes, they will run both old and new system in parallel way to com-pare the results. In still other situations, system developers stop using the old system one day and start using the new one the next.

13. SECURITY MEASURES TAKEN
In security measure taken we have discussed what security measures we should apply on “NK GAS AGENCY”. What kind of security measures should be applied for the security of databases and how we manage it?
Although there are many measures of software quality, correctness, maintenance, integrity, and usability provide useful indicators for the project team.
Software integrity has become increasingly important in the age of hackers and firewalls. The attributes measure a system ability to stand with attacks to its security.
Attacks can be made on all three components of software:
• Program
• Data
• Document
To measures integrity we must be defined two additional attributes:
• Threat
• Security
Threat is the probability that an attack of a specific type will occurs with in a given time. Security is the probability that the attack of a specific type will be repelled.
To tackle with some of the problems mentioned above we will develop a user authentication module that uniquely identifies the Administrator, valid or invalid users.
14. COST ESTIMATION
Software cost and effort estimation will never be an exact science. To many variables-Human, Technical, environmental, Political can affect the ultimate cost of software and effort applied to develop it. However, software project estimation can be transformed from a black art to a series of systemic steps that provides estimates with acceptable risk.
To achieve reliable cost and effort estimates, a number of options arise:
We can achieve 100% accurate estimates after the project is complete.
Base estimates on similar projects that have already been completed.
Use relatively simple decomposition techniques to generate project cost and efforts and
Use one or more empirical models for software cost and effort estimation.
The first option is that the cost estimates must be provided “up front”. However, we should recognize that the longer we wait. The second option can work reasonably well, if the current project is quite similar to past efforts and other project influences.
The remaining options are viable approaches to software project estimation. Ideally, the techniques noted for each option should be applied in tandem.
Each of the viable software cost estimation option is only as good as the historical data used to seed the estimate.

15. FUTURE SCOPE
Despite a lot of support and services are being provided by the software, it may have the some limitations which can be overcome by adopting the following measures such as:
• Can provide record based security.
• Can have better record traversal mechanism.
• Can provide backup for records.
• Can provide different rights to different users.
Some of the improvements that have been predicted in future are as follows:
1. Create a Asp page in which an agency administrator can enter a month and year.
System will display the sales data based on the month and year entered by the administrator of agency.
2. Create a monthly report providing the details about the status of items in the agency. The report should be displayed in the following format:
NK Gas Agency
Booking Details for the Month- Year---Card No Cylinder Description Quantity on Hand
3. Create a daily report providing the details of the transactions for each day in the OBS. The report should be displayed in the following format:
NK Gas Agency Transaction Details
Card No Tran no Transaction
Date Quantity Amount
4. Create a report that will be given as a bill to the customer after the customer purchases the required items. The report should be displayed in the following format:
AL-FALAH SCHOOL OF ENGINEERING & TECHNOLOGY,FARIDABAD NK Gas Agency
Faridabad, India
Date: --/--/--Customer Number:
Customer Name:
Card-No Cylinder Description Quantity Amount
Total Amount:
