We usually live in a world, where we have several programming languages around us. Each programming language has its own importance. We could not say exactly which programming languages meet all the requirements of the end-user. These programming languages play a major role in both tool programming as well as cloud programming. No miracle if the programming language used like APEX in Salesforce.
Importance of a programming language, known when the programming language is used even in a cloud server. Today, in this IT world, we have several cloud providers like Salesforce which is used by most of the IT users today. Salesforce cloud service uses a programming language called APEX.
Learn Apex Programming language with Salesforce online Training.APEX in Salesforce:
Apex is a proprietary language developed by salesforce. Basically, APEX is a strong objected oriented programming language that allows developers, to execute the flow and transaction control statements on salesforce.
Basically, APEX is similar to JAVA syntax and acts as a database and stored in a procedure. The major advantage of this language, it allows developers to perform some action button clicks, recorded updates, etc. Moreover, APEX includes Unlimited edition and Enterprise edition.
Architecture:
The architecture of APEX is shown below :
APEX uses two kinds of actions namely Developer action and End-user action. Let us discuss each action briefly.
Developer action:
Here in this action, the developer writes and saves the APEX code to the cloud platform, this platform application server first compiles the code and then send it into a set of instructions. These instructions understood by the compiler and then saves this data as metadata.
End-User Action:
When the end-user triggers the execution of APEX, by clicking a button (or) accessing a visual source page this APEX platform retrieves the run-time data, which previously saved as run-time metadata and sends through the run-time interpreter, before generating the result.
You can develop this APEX code either in a sandbox (or) a developer edition of Salesforce. Basically, this sandbox is a copy of your organization, where you can write the code and test it without taking, the risk of data modification (or) disturbing the normal functionality. It is a good way to develop the code in a sandbox, and then deploy them into the production environment.
This APEX has great features when compared to other programming languages. Let us discuss each feature in detail.
Integrated:
The integration of some operations makes the programming languages, more user-friendly. This APEX provides built-in support for DML operations like INSERT, UPDATE, DELETE. Moreover, It also supports SOSL and SOQL query handling, which returns a set of Subjects records.
Easy to use:
The syntax used in APEX is easy and simple to use and similar to JAVA.
Multitatent Environment:
APEX runs in a multitenant environment. Moreover, its runtime engine defined to have guard against runaway code. Any code that violates the rule will result in the easy display of messages.
Easy testing:
Testing is an important phase in any programming language. A programming language is more flexible if it can perform multiple testing like unit testing, this unit testing indicates how much part of data was error-free, now and which parts of codes suites well for the programming languages.
Along with the above-mentioned queries, there are many other features that cannot be explained in a single blog. In the upcoming Blogs, we will update more data on this Topic.
