Ans. Grand Park Group is a hospitality company having its head office in Chicago. Grand Park Group is currently in the process of opening its first hotel in the Dallas city. The hotel named Grand Park Regency is a mid-budget hotel with 25 rooms. Grand Park Regency has already hired employees required to operate the hotel and started promotional activities through the print and electronic media. Customers who plan to stay at the hotel will be able to book one or more rooms by visiting the hotel. The hotel receptionist checks for room availability, and after confirmation from the customer, books the room for the specified number of days. At the end of each day, the receptionist generates a report on the room occupancy of the hotel and sends an email attaching the report to the head office. The management of Grand Park Group is aware of the need to automate the operational processes of the hotels to be established. The management wants a system that is modular and can scale with the increase in the volume of operational processes. For this, the management hires Zoom Systems, an IT consultancy firm, to create Hotel Management System (HMS). You are a Java developer at Zoom Systems and have been assigned to work in a team designing and developing HMS. Based on the initial inputs from the management of Grand Park Group, HMS will be released in a phased manner. In the first release, HMS should automate the customer-booking and room-occupancy reporting modules to be used in the Grand Park Regency hotel. Based on the initial requirement gathering, you have analyzed that Grand Park Regency hotel currently has the following categories of rooms:  Standard Room  Executive Room  Family Room In subsequent meetings, you have gathered the requirements of HMS. Initially, HMS will be a standalone application used by the receptionist at the Grand Park Regency hotel. HMS should allow a receptionist to search for the available rooms and book the same for a customer. In addition, HMS should allow a receptionist to generate the room occupancy report of the hotel for each month and store it in the file system as a text file. HMS should also allow the receptionist to daily update the room occupancy report file. A room occupancy report file for a month contains the following pieces of information:  The daily report generation date and time  The total number of rooms occupied under each room category on a day HMS should allow the receptionist to archive the room occupancy report at the end of each month, and create a new report for the next month. You have been assigned the task of analyzing the scenario and leading the team in creating HMS.

1.  The design team at Janes Technologies has been assigned a task to create a state chart diagram for the InfoSuper bank ATM system. For this, the team needs to perform the following tasks:
 Identify the states of the ATM.
Identify events responsible for state changes.
Model the flow of control between the states of the ATM. Help the team at Janes Technologies to perform this task.

Ans  To create the state chart diagram for the InfoSuper bank ATM system, you need to perform the following tasks:
1. Identify states.
2. Identify events and transitions.
3. Model the flow of control between the states.
Identifying States
The following states can be attained by an ATM system:
• Reading ATM Card
• Authenticating Customer
o Reading PIN
o Sending to Bank System for Validation
• Accepting Transaction Type
• Accepting Transaction Details
• Sending to Bank System for Approval
• Processing Transaction
• Prompting for Another Transaction
• Handling Invalid PIN
• Dispensing Cash
• Printing Slip
• Ejecting Card
Identifying Events and Transitions
The following events and transitions take place in the state machine diagram:
• When a customer inserts a card into the ATM machine, the state of the machine changes from initial state to Reading ATM Card.
• When a customer inserts a PIN. the state of the machine changes from Reading ATM Card to Reading PIN. which is the sub state of the Authenticating Customer state.
• To authenticate the PIN. the state changes from Reading PIN to Sending to Bank System for Validation. If the customer enters a valid PIN. the state changes to Accepting Transaction Type. Otherwise, it changes to Handling Invalid PIN.
• If the customer enters the PIN maximum number of times, the state changes to Ejecting Card. Otherwise, it changes to Authenticating Customer state.
• After successful authentication of a PIN. the state changes to Accepting Transaction Type.
• When the customer selects the transaction type, such as Cash Withdrawal or PIN change, the state changes to Accepting Transaction Details.
• When the customer enters the transaction details, the state changes to Sending to Bank System for Approval. If the transaction is approved by the Bank System, the state changes to Processing Transaction. Otherwise.it changes to Prompting for Another Transaction.
• Similarly, if the customer selects cash withdrawal as the type of the transaction.the state changes from Processing Transaction to Dispensing Cash. However, if the customer selects to get the transaction summary, the state changes to Printing Slip.
• When the transaction is complete, the state changes to Prompting for Another Transaction.
• If the customer does not wish to continue for another transaction, the state changes from Prompting for Another Transaction to Ejecting Card. However, if the customer wishes to continue, the state changes to Accepting Transaction Type.


2.  The design team at Janes Technologies has been assigned a task to model the flow of activities required to be performed for withdrawing cash from an ATM. For this, the team needs to create an Activity diagram. Help the team at Janes Technologies to create the Activity diagram.


Ans  To create the activity diagram of the cash withdrawal process, you need to perform the following tasks:
1. Identify activities and decisions.
2. Identify partitions.
3. Create an activity diagram.
Identifying Activities and Decisions
A process consists of various activities that you need to identify before you can establish control flow among them. The sequential activities for the cash withdrawal process are:
• Insert Card: Signifies the activity to insert the ATM card in the ATM.
• Enter PIN: Signifies the activity of the bank customer to enter the PIN.
• Accept PIN: Signifies the activity of ATM machine to accept the PIN.
• Validate PIN: Signifies the activity of ATM card to validate the PIN.
• Display Invalid Card Message: Signifies the activity of ATM to display an invalid message, if the PIN entered by the user is incorrect.
• Prompt User Input: Signifies the activity of ATM to prompt the user to initiate a transaction.
• Initiate Withdrawal: Signifies the activity for the bank customer to initiate the cash transaction.
• Prompt User for Withdrawal Amount: Signifies the activity of ATM to prompt the user to enter the amount in the system.
• Enter Amount: Indicates the activity to enter the amount in the system.
• Check Available Balance: Signifies the activity of bank account to check the available balance in the user's account.
• Display Insufficient Balance Message: Signifies the activity of ATM to display a message for insufficient balance to the user.
• Prompt User to Continue: Signifies the activity of ATM to ask the user to continue.
• Collect Cash: Indicates the activity of the bank customer to take the money from the ATM machine.
• Supply Cash: Signifies the activity of ATM to supply cash to the customer.
• Eject Card: Indicates the activity of the bank customer to take the card back from the ATM machine.
The following decisions are made in the process of withdrawing money:
• Validate PIN: Confirms the validation of the PIN entered by the user. If it is invalid, the system prompts the customer to enter another PIN.
• Check Available Balance: Checks the available balance in the account. If the amount withdrawn by the user is greater than the available balance, the system prompts the user to enter an amount less than the available balance.
Identifying Partitions
Partitioning is done to logically group the activity states so that each group represents the responsibility of a particular class. To partition the activity states, you need to create swim lanes for the following classes:
• Bank Customer
• ATM
• ATM Card
• Account

1. The design team at Janes Technologies has created the prototype for the InfoSuper bank ATM system. Now, the InfoSuper bank wants the team to model the static structure of the system. For this, the team needs to derive classes and relationships from the use cases of the ATM machine and create the corresponding class diagram. Help the team at Janes Technologies to perform this task.


Ans. To create the required class diagram, you need to perform the following tasks:
1. Identify the classes with their attributes and methods.
2. Identify the relationships between the classes.
Identifying the Classes with Their Attributes and Methods
The following classes can be created for the ATM system:
• ATM Card: Maintains the details of the ATM card, such as pin and card id. It performs the actions of accepting PIN from the user, validating PIN based on the information stored in the database, and updating PIN on user demand.
• ATM: Maintains the details of the ATM machine, such as its location, bank branch, and available cash. It performs the actions of making a transaction from the ATM, such as accepting the card, reading the card, accepting PIN. withdrawing cash, and printing transaction summary.
• Account: Maintains the details of an account, such as the account number, and balance. It performs the actions of retrieving the account details and checking and updating account balance.
• Current Account: Maintains the details of the current account. Apart from the details mentioned in the Account class, it also includes an additional attribute for maintaining the overdraft limit for the current account.
• Saving Account: Maintains the details of the savings account. Apart from the actions mentioned in the Account class, it also calculates the rate of interest for the savings account type.
• Bank Customer: Maintains the details of the bank customer, such as customer name, phone number, and email address. It performs the actions of retrieving and updating the customer details.
• Address: Maintains the details of the address of the bank customer, such as house number, city, state, country, and zip code. It performs the actions of retrieving and updating the address details.

Identifying the Relationships Between the Classes
The following relationships can exist between the classes of the system:
• Each ATM card is associated with an account. Therefore, the ATM Card class has one-to-one association relationship with the Account class.
• ATM verifies whether an ATM card is valid or not. Therefore, the ATM class has a directed association relationship with the ATM Card class.
• A bank customer uses ATM for money transactions. Therefore, the Bank Customer has a directed association relationship with the ATM class.
• An account can be of the type, current or savings. The accounts have some common as well as different attributes. Therefore, there are two classes. Current Account and Savings Account, which generalize to form the Account class.
• A customer can have multiple bank accounts. In addition, one account can be associated with multiple account holders. Therefore, the Bank Customer class has a many-to-many association relationship with the Account class.
• A bank customer can have one permanent address. Therefore, the Bank Customer class has a one-to-one composition relationship with the Address class.

1. The Project Manager at Janes Technologies has created the use case diagram for the InfoSuper bank ATM system. Now, the InfoSuper bank wants Janes Technologies to develop a prototype with few basic functions of the proposed software system before proceeding with the final software development. The functions that the InfoSuper bank wants in the ATM prototype are:
 Allow customers to withdraw cash from the current and savings accounts. 
Allow customers to change their PIN. 
Allow customers to obtain a transaction summary. Moreover, the ATM machine validates the ATM card and PIN of the bank customers before allowing them to use other features. The Project Manager, Jennifer, adopts an iterative approach for the development of the software system. She decides to deliver the prototype after the second iteration of the software development life cycle. In the first iteration, Jennifer plans to implement the required functions only for the savings accounts. In the second iteration, she plans to implement the required functions for the current accounts as well. Help Jennifer to identify the system boundaries and create the use case diagrams for each prototype.


Ans  To create the use case diagram of the ATM system, you need to perform the following tasks:
1. Identify the use cases and actors for the first iteration.
2. Identify the use cases and actors for the second iteration.
Identifying the Use Cases and Actors for the First Iteration
To identify the system boundary for the first iteration, you need to identify the use cases and actors. The use cases for the first iteration are:
• Cash Withdrawal (Savings)
• PIN Change (Savings)
• Transaction Summary (Savings)
The actors for the first iteration are:
• Bank Customer
• Centralized Bank System
In the first iteration, the Cash Withdrawal (Savings). Change PIN (Savings), and Transaction Summary (Savings) use cases can be performed only when the customer is validated by the centralized bank system. Therefore, the Validation use case should be included in the Cash Withdrawal (Savings), Change PIN (Savings), and Transaction Summary (Savings) use cases.
Identifying the Use Cases and Actors for the Second Iteration
In the first iteration, the use case diagram for the savings account is created. Now. in the second iteration, the use cases need to implement the current account function. The basic functions of the corresponding use cases in both the iterations are the same. Therefore, the functions of the use cases of the first iteration can be extended to obtain the use cases of the second iteration.
The following figure depicts the use case diagram that represents how the functions of the use cases of the first iteration can be extended to obtain the use cases of the second iteration.

Ans                                                                  MVC
The MVC model is an alternetive to the ASP.NET Web form model for devoping web  application it is a light-wight model and suport existing ASP.NET feature. It separateds the following three main companents. It separates the following three main componets from an application:

Model: Refer to a set of classes that describes the data that the application works with. In addition, these classes define the bussines logic that governs how the login form that contains text boxes boxes an buttons.

View: Refers to the components that define an application user interface. for example, the login from that contain text boxes and buttons.

Controller: Refres to a set of classes that handle commnication from the user and the overall application flow . A controller responds to user input, communicates with the model, and decides the view to render. By seprading model, View, and controller within an application , the MVC model ensure loose compling. Therefore, it enables you to focuse on one aspect of the implementaion at a time. Foe eample, you can concentrate on designing a view without worrying about thebussiness logic.

The MVC model makes it easier to manage complexcity by dividing an application into the model, the view, an the controller. Therefore, it should be used for developing web application that are managed by larges tearms of devlopers and web designer.

                                                   The Asp.net Impementaion of MVC

In MVC, incoming request are handled by controllers. Controllers are C# that contain methods. Each public method in a controller is known as an action method can be invoked by using a URL. when an HTTP request is sent to the server by using a URL is executed in order to perform the requried opration on a model. Than a view is rendered and display to the clint. The following figure displys the interation between the controller, the model, and the view.

1. Explain the benefits of ASP.NET MVC.


Ans  The ASP.NET MVC is an open source web application framework that implements the model–view–controller (MVC) pattern.
Based on ASP.NET, ASP.NET MVC allows software developers to build a web application as a composition of three roles: Model, View and Controller. The MVC model defines web applications with 3 logic layers:

Model (business layer)
View (display layer)
Controller (input control)
A model represents the state of a particular aspect of the application.
A controller handles interactions and updates the model to reflect a change in state of the application, and then passes information to the view.
A view accepts necessary information from the controller and renders a user interface to display that information.



ASP.NET MVC framework is a lightweight, highly testable presentation framework that is integrated with existing ASP.NET features.
Some of these integrated features are master pages and membership-based authentication. The MVC framework is defined in the System.Web.Mvc assembly.
The ASP.NET MVC Framework couples the models, views, and controllers using interface-based contracts, thereby allowing each component to be tested independently.
The view engines used in the ASP.NET MVC 3 and MVC 4 Frameworks are the Razor View Engine and the Web Forms view engine. Both view engines are part of the MVC 3 framework. By default, the view engine in the MVC framework uses Razor .cshtml and .vbhtml, or Web Forms .aspx
