4. External interface requirements 4.1 User interface  Login Screen: This is for the administrator to get into the software. It requires a user name and password.  Account Details: this shows the account status of various users with their login times.  New registrations: this utility is to create new users or clients in the CYBER CAFE MANAGEMENT SYSTEM.  Reports: this is used to generate reports of the login and account details of users.  User login (client side): the user has to give a username and password by which he or she can access internet.  User Account: this enables the user to view the account status Of their account. 4.2 Hardware interfaces The server is directly connected to the client systems.also the client has to access to the database for accessing the account details and storing the login time. The client access to the database in the server is only read only. 4.3 Software interfaces CYBER CAFE MANAGEMENT SYSTEM is a multi-user, multi-tasking environment. It environment. It enables the user to interact with the server and attain access to the internet and also leaves a record in the inbuilt database. It uses java servlets as the front end programming tool and SQL as the backend application tool. 4.4 Communication interfaces The CYBER CAFE MANAGEMENT SYSTEM uses java Servlets and hence require HTTP for transmission of data. More over this allows easy interaction between the various clients and the server.

5. Other non-Functional Requirements 5.1 Performance Requirements The important aspects of CYBER CAFE MANAGEMENT SYSTEM software is time constrain. CYBER CAFE MANAGEMENT SYSTEM software system is real time and hence should be performed in minimum requirements. The accountability is a vital feature and this could only be assured if the system is working in full capability. So uninterrupted power supply is needed. 5.2 Safety Requirements The data handled in the cyber cafe system is very vital. The server should always be confirmed to run properly and data are saved to the database at consecutive intervals. Power is a significant feature and the power supply should be always taken care of. An uninterrupted power supply is always recommended. 5.3 Security Requirements The security system features from having a login for all the users To access the software. The login details will be used in the system also. So the chances of the software getting intruded are very less. 5.4 Software Requirements The source code of the product is going to be open as this is going to be open source software. It will be free for further modifications and improvements. 5.5 Business Rules Illegal duplication of the reports should be strictly dealt with.the administrator should have full details of the user while a user is getting registered to the system. 5.6 Special Requirements 5.6.1 Backup and Recovery

19

Cyber Café Management System 2016  Keeps backups of all data files in a separate directory/drive.  Frequently auto-save information, in the case of a lost network connection, the browser or the system crashing, etc. 5.6.2 Data migration The concept of Data migration is important to ensure that the data that is being entered and stored today could be accessed After even several years. 5.6.3 Data retention Maintaining a log file for each user logging ina nad also maintaining the account details of the users who have finished the account could be obtained from cyber café reports. 5.6.4 User training Clients must be trained to operate the cyber café software in creating new accounts and performing report operations. 5.6.5 Installation A Conductive environment for the efficient running of the cyber café recommended. The server should be handled with great care and all unauthorized access should be restricted.

6. PRELIMINARY SCHEDULE: The system has to be implemented within 6 months.

7. OPERATIONAL SCENARIO: This system consist of student database, staff database, servers, various complain databases etc. The major actors in this system are:General users: They will be position to permit access to the users in the internet and acknowledge their account status. Administrators: They are the core users able to add the new users to the system and permit them to access the internet resources. They can also view in real time what a user performing right now. They can also get the overall report of the user sessions. Employees: They login at the client level and this is to get access to the internet at the client level. They can also view their account status in the client system.

Scenario:  Initial Situation: A registered customer logins using User-ID and password and surfs.  Normal flow of events: In Cyber Cafe Management System, initially the customer visits the café. If he is not registeres, then he must provide login credentials along with proof and registered himself. He will then create a password on specified terminal using ID provided by employee.

21

Cyber Café Management System 2016 On other hand if user is registered, then he will login into his account and access the net or takes an printout of necessary document.  What can go wrong: If the registered user forgets the password & on pressing “Forget Password” option he is provided with security questions, but still if user is enable to answer these questions. If the newly arrived customer forgets to bring th Id proof, he will not be allowed to access the net. Printing issue while print command senr by user due to some technical problem The customer faces difficulty in accessing the internet & the available employess will help him.  Other activities: Café owner sales different computer accessories useful for customer.  System state on completion: The customer [ays the bill for surfing, priting or purchasing any product.

9. Testing

9.1 About Testing: Testing is a process that requires more efforts than any other software engineering activity. Testing is a set of activities that can be planned in advance and conducted systematically. This may lead to have many undetected errors in the system being developed. Hence performing testing by adopting systematic strategies in very much essential in during development of software.

Various testing strategies for conventional software are :1. Unit Testing :In this type of testing techniques are applied to detect the errors from each software component individually . 2. Integration testing :It focuses on issues associated with the verification and program construction as components begin interacting with one another. 3. Validation testing :It provides assurance that the software validation criteria (established during requirement analysis) meets all functional , behavioral and performance requirements . 4. System testing :In system testing all system elements forming the system is tested as a whole.

9.3 Black Box Testing It’s also called as “behavioral testing”. It focuses on functional requirement of the system. As per the name suggests in black box testing it is tested whether the input is accepted properly and output is correctly produced. Equivalence Partitioning: In this technique, if an input condition requires a specific a range, one valid and two invalid equivalence classes are defined.  If an input condition requires a specific value, one valid and two invalid equivalence classes are defined.  If an input condition specifies member of a set, one valid and two invalid equivalence classes are defined.  If an input condition is a Boolean, one valid and two invalid equivalence classes are defined. Equivalence Partitioning for Cyber Cafe Management System is :Log in Module: Input conditions:- Valid username, valid password Test values:- 1.(Bhoomika, bhumu123) 2.(nnn,nn)

Website Blocking/Tracking Module: Input conditions :- (Website name, No of days ) Test values :- 1.(www.facebook.com,15) 2.(xyz.com,-3)

30

Cyber Café Management System 2016

Accounting Module: Input conditions :- (Invoice No,Customer_Id,Cust_Name, Items, Quantity) Test values :- 1.(001,C01,Unnati,Pen-drive,2) 2.(xyz,-1,-456,1,-1)

Bandwidth Monitor Module: Input conditions :- (limit) Test values :- 1.(1GB) 2.(-1000MB) Boundary Value Analysis (BVA) : Boundary value analysis is done to check boundary conditions.  Using boundary value analysis , instead of focusing on input conditions only, the test cases from the output domains are also derived.  It is a complement to the equivalence partitioning.

12. Cost Estimation

Function Point calculation Function points (FP) measure size in terms of the amount of functionality in a system. Function points are computed by first calculating an unadjusted function point count (UFC). Counts are made for the following categories     

Number of user inputs Number of user outputs Number of user inquiries Number of files Number of external interfaces

Once this data has been collected, a complexity rating is associated with each count according to Table

TABLE 1: Function point complexity weights.
