2.5 REQUIREMENT ANALYSIS

1)Salesforce

Salesforce.com is a cloud computing and SaaS(Software as a Service) provider headquartered in San Francisco. The company was founded in March 1999 and is well known for its CRM (Customer Relationship Management) product which comprises of Work.com, Sales cloud, Force.com ,Marketing cloud ,Service cloud and Chatter.

Services provided:

  1. AppExchange
  2. Chatter
  3. Dashboards and Reports
  4. Email
  5. Campaigns , Leads and Opportunities

Salesforce uses MVC architecture for providing better performance to its consumers where:

M: Model

V: View

C: Controller

Model: It represents the data and the schema which are utilized by the Salesforce to completely represent the system. In Salesforce, we can assume that the sObjects act as models as every entity in salesforce is mapped to some sObjects. It notifies its associated views and controllers when there has been a change in its state.

View: Aviewrequests from the model the information that it needs to generate an output representation. It focuses on how the schema and data is represented.Visualforce is used to present the data to users.

Controller: Acontrollercan send commands to its associated view to change the view’s presentation of the model (e.g., by scrolling through a document). It can also send commands to the model to update the model’s state (e.g., editing a document).

2) APEX

Apex is an object oriented programming language for development on Force.com platform and the calls can be made to the Force.com API. Apex helps in adding business logic to the events in a system making use of button clicks, writing VisualForce pages and apex code can be initiated through triggers.

Apex is a strongly-typed, object-oriented programming language that lets you centralize and execute flow and transaction control statements on the Force.com platform in conjunction with application calls to Force.com ​APIs. Using syntax that looks like Java and acts like database stored procedures, Apex lets you add powerful custom business logic to most system events, including button clicks, related record updates, and Visualforce pages. Web service requests and database triggers on objects can also initiate the execution of Apex code.

As a language, Apex is:

Integrated

Apex provides built-in support for common Force.com platform idioms, including:

• Data manipulation language (DML) calls, such as INSERT, UPDATE, and DELETE, that include built-in

DmlException handling

• Inline Salesforce Object Query Language (SOQL) and Salesforce Object Search Language (SOSL) queries that

return lists of sObject records

• Looping that allows for bulk processing of multiple records at a time

• Locking syntax that prevents record update conflicts

• Custom public Force.com API calls that can be built from stored Apex methods

Apex

Use Apex if you want to:

• Create Web services.

• Create email services.

• Perform complex validation over multiple objects.

• Create complex business processes that are not supported by workflow.

• Create custom transactional logic (logic that occurs over the entire transaction, not just with a single record or object.)

• Attach custom logic to another operation, such as saving a record, so that it occurs whenever the operation is executed,

regardless of whether it originates in the user interface, a Visualforce page, or from SOAP API.

Figure 3: Programming elements in Apex

Apex has the following types of collections:

• Lists (arrays)

• Maps

• Sets

A list is a collection of elements, such as Integers, Strings, objects, or other collections. Use a list when the sequence of elements

is important. You can have duplicate elements in a list.

List My_List = new List();

List list_name

[= new List();] |

[=new List{value [, value2. . .]};] |

;

A set is a collection of unique, unordered elements. It can contain primitive data types, such as String, Integer, Date, and so

on. It can also contain more complex data types, such as sObjects.

Use the following syntax for creating a set:

Set set_name

[= new Set();] |

[= new Set{value [, value2. . .] };] |

;

The following example creates a set of String. The values for the set are passed in using the curly braces {}.

Set My_String = new Set{‘a’, ‘b’, ‘c’};

A map is a collection of key-value pairs. Keys can be any primitive data type. Values can include primitive data types, as well

as objects and other collections. Use a map when finding something by key matters. You can have duplicate values in a map,

but each key must be unique.

Map map_name

[=new map();] |

[=new map

{key1_value => value1_value

[, key2_value => value2_value. . .]};] |

;

The following example creates a map that has a data type of Integer for the key and String for the value. In this example, the

values for the map are being passed in between the curly braces {} as the map is being created.

Map My_Map = new Map{1 => ‘a’, 2 => ‘b’, 3 => ‘c’};

Visualforce

Visualforce consists of a tag-based markup language that gives developers a more powerful way of building applications and

customizing the Salesforce user interface. With Visualforce you can:

• Build wizards and other multistep processes.

• Create your own custom flow control through an application.

• Define navigation patterns and data-specific rules for optimal, efficient application interaction.

Enable Visualforce Development Mode

Development mode embeds a Visualforce page editor in your browser that allows you to see code and preview the page at the

same time. Development mode also adds an Apex editor for editing controllers and extensions.

1. Click Your Name > Setup > My Personal Information > Personal Information.

2. Click Edit.

3. Select the Development Mode checkbox, then click Save.

Your Stuff Here

Step 2: Add Additional Components

You’ve created a page, used the component, and changed its behavior. You’ll typically want to use additional

components that supply a lot more functionality.

Visualforce comes with a few dozen built-in components, and you can install and build your own components to extend this

set. In this lesson you’ll learn how to locate them, and use one.

1. Click the Component Reference link in the Page Editor. A help popup window displays with all available components.

2. Click . A description of what the component does, and what attributes you can add to change its

behavior displays in the Component Details tab.

3. Click the Usage tab to see an example of how to use the component. You’ll notice that the component

is often used with the component. Click to learn more

about that component.

In general, you’ll dip into the component reference whenever you need to. You’ll soon learn what the major components

do—and while some of them take a large number of attributes, in practice you will only use a handful.

Now add both components to your page. We’re going to go a little faster here—see if you can do this without looking at

the final code below:

4. Within the component, add an component with a title attribute set to A Block

Title.

5. Within the component, add an component, with its title attribute

set to A Section Title.

6. Within the , add some text, like I’m three components deep!

7. Click Save. Your final code will look something like this:

I’m three components deep!

Step 3: Add Nested Components

I’m three components deep!

This is another section.

What are the Limitations of Apex?

Apex radically changes the way that developers create on-demand business applications, but it is not currently meant to be a

general purpose programming language. As of this release, Apex cannot be used to:

• Render elements in the user interface other than error messages

• Change standard functionality—Apex can only prevent the functionality from happening, or add additional functionality

• Create temporary files

• Spawn threads

Features of Apex:

  1. Apex is integrated: Apex provides built in support for DML calls, SOQL and SOSL queries, looping , locking syntax and making custom API calls.
  2. Apex is easy to use: Apex resembles Java and the syntax and semantics are quite familiar and thus the code is easy to write and understand.
  3. Apex is data focused :Apexis designed to combine multiple queries and DML statements into a single unit of work on Force. com.
  4. Apex is rigorous :Apex is a strongly typed language and stores all custom objects , fields , class dependencies in metadata so that active apex code can make use of it and there is no risk of deletion.
  5. Apex is hosted: Apex is implemented and controlled completely by Force.com platform.
  6. Apex is multitenant aware :Apexruns in a multitenant environment and specially designed to help against runaway code.
  7. Apex is automatically upgradable :No separate changes have to be made to Apex when the system is upgraded ; it gets updated automatically with the system.
  8. Apex is easy to test :Apex provides built in support for unit testing and thus you can test if all your classes and objects are working accordingly before putting your app in the SendBox.

3) MICROSOFT VISUAL STUDIO 2010

It is an IDE {Integrated Development Environment} by Microsoft. It is used to develop programs for Windows as well as websites and web services. It supports different programming languages.

Two types of applications can be built using VB.NET:

VB.NET has various important features:

  1. It is an object oriented language and supports inheritance.
  2. It is type safe and supports exception handling.
  3. Other features are method overriding, overloading, constructors with parameters, multithreading etc.

Events in VB.NET: Events are defined by using the Event keyword.

Overview of current working

The Secure Content Management and Data Migration on Cloud is managing all customers, orders, and transactions with the help of a Content Management application implemented on the Salesforce using the Apex programming language.

The objects involved are as following:

  1. User
  2. Product
  3. Order
  4. Order Detail
  5. Transaction
  6. Complaint

The process of the Secure Content Management is as follows:

3.1 User Registration

This step involves the registration of the new customer requiring the relevant information. When the registration is successfully done, then a mail is triggered to the customer on its Email Id which contains its Username and Password which the user requires while login.

3.2 Login

Once the customer login into its account, a User Id is being allotted to him which is required in the application for various purposes.

3.3 Order

This step involves the following sub Processes:

  1. Initiation of Order

This step involves receiving order from customer selecting the products from various products available and also in stock. While ordering, an Order Id is being generated on each order and is provided to the customer for its record basis or for any query .

  1. Order List

This tab views all the orders list which was being placed by the customer along with their Order Id, Product being ordered and the Order amount and quantity.

  1. Order Info

This functionality performs the function of finding the status of the order being placed by the customer based on the Order Id.

3.4 Order Trigger

A trigger is being implemented on the Order object such that when any order is being placed, a mail is received by the customer containing the Order Id, Status, Amount and other relevant information.

3.5 Transaction

While the order is being placed the customer create a new transaction which generates a transaction Id and sends the request to the bank for further process.

It is supposed that when the acknowledgement is being received from the bank, the admin updates the status of the Order of the customer and a mail will be received by the customer related to the successful transaction.

It also contains the list of all the transaction and also the transaction search function.

3.6 Complaint

If the customer is having any complaint related to the company or the product or any service, then the customer can file a complaint in this section to the authority and a complaint Id will be provided to him for any query or search.

The complaint will be send to the respective member of the company which will perform the necessary actions.

3.7 Generate Bill

Once the order is being completed, a bill will be generated containing all the necessary information required by the customer.

The system also has the additional functionality:

1. The administrator has full control over the system and has the authority of keeping the information secure by deciding data accessibility based on roles and permissions

2. The administrator can track all the activities happening on the system.

3. Dashboard reports can be generated in order to gain graphical insight of the data.

4. Leads and opportunities can be managed which help in the growth of the business.

5. Automatic mails are sent to the user on creation of an account, placement of an order, and on any change in the order status.

6. Workflows and approval processes can be created within the company for the approval required on things.

7. A data migration application has been designed using VB.NET which is integrated with the Salesforce app and helps in migrating data to the cloud through this desktop application. The whole process is secured by generating a unique security token.
