What is Customisation/non Declarative approach in Salesforce?

Hello,

We live in a digital world. To keep up with employee and customer expectations, innovation through technology is increasingly becoming a nonnegotiable. Whether it’s a website to direct customers your way, an app to help improve their experience, or another project altogether, this naturally means that some kind of software development is needed.

To accomplish your goals, there are two types of programming you can turn to: imperative programming and declarative programming. Both have benefits, but how do you figure out which is best for you? First, it’s important to understand the difference between them.

Imperative programming, otherwise known as traditional or code-oriented programming, denotes the means of programming by using certain coding languages — such as C#, C++, Java, and so on — to tell a computer exactly how to perform an action. This requires a skilled developer with programming knowledge. This developer will build the application brick by brick using blocks of code, usually in a terminal window or some other highly specialized development environment.

On the other hand, declarative programming accomplishes the same results by basically telling the computer the end result and letting the computer figure out how to get there. In simpler terms, declarative programming denotes the kind of click or drag-and-drop solutions that allow someone without coding knowledge to build an application. The blocks of code are prewritten and packaged into components that you can just select as needed.

While there are certainly benefits of traditional imperative programming — experienced programmers prefer the freedom given by a more open source environment — most business leaders and entrepreneurs looking to create an application benefit from using those declarative programming drag-and-drop solutions.
