Designing an application on Force.com

Before we start designing an app on the Force.com platform, we need to consider the type of data that will be processed by the developed app. Four distinct types of apps can be designed, and before designing the app you need to decide your app falls into which category.  These are four types are:

  • Datacentric apps: These are the apps that are based on databases, such as data stored in XML structure. With the help of these apps, the data on the databases can be easily controlled with minimal intervention. Force.com is by default structured to host the data-centric apps.
  • Process-centric apps: These are the apps that automate the underlying business processes, and engages multiple users for the same.  Force.com has well design workflow, approval process, and sharing models, that can be used for automating business processes.
  • Content centric apps: These are the apps that facilitated on-demand performance, with dedicated storage.  Force.com provides a perfect platform for content sharing and content management while implementing a version control system at the same time.
  • Transaction-centric apps: These are the apps used for transaction processing systems, such as banking apps, payment apps, stock trading, etc.

Hence, before even designing the app, the app needs to be classified.

Apart from identifying the app type, also identify the user group or the stakeholder. It could be a small group, departmental users, enterprise users, and a large number of enterprise users.

Force.com is an integrated development environment, where one needs to write the code in an editor, compile and run the app. There are many app builder tools available on the Force.com platform. Some of the key app builder tools are mentioned below,

  • Apex Classes: This is a template that is used for creating the Apex objects. It contains other classes, variables, exceptions, and user-defined methods. For example, there is an Apex Object named Invoice, it will have all the functions and variables that might be required to process an invoice.
  • Apex Triggers: Apex triggers are used for performing custom actions. It can be used as after-changes to a record in Salesforce. This includes activities like insertion, deletion, and updation.
  • Components: Components available on Force.com can be customized as per business logic, to develop a customized app for the salesforce.com.
  • Pages: Just like components, force.com allows the creation of customized pages catering to the business needs and user needs.

In the above screen, Multiplication is the name of the Apex Class, and once this class is created, it will be listed with the same name.  Similarly, Apex Trigger and VisualForce components can be developed. However, for developing VisualForce components, the developer environment in Salesforce needs to be activated first. By enabling the developer mode in Salesforce, we can code as well as compiled in the same window.
