Introduction to Salesforce Apex Training
Apex is a strongly typed object-oriented programming language that allows developers to execute flow and transactional control statements on the salesforce servers. Along with this they can also make calls to different APIs. Apex syntax is the same as that of java syntax. Apex enables developers to add business logic to most system events which includes button clicks, record updates and creating visual force pages. Apex validates the reference to the object at the compile time. As it is an object-oriented programming language it supports classes, inheritance and interfaces. All the apex code is saved, compiled and executed on the sales force server. Ides Trainings provides the best Salesforce apex training as we have highly qualified industry expert trainers.

Overview of Salesforce Apex Training:
When the implementation of complex functionality using the pre-built and existing out-of-the-box functionalities of the salesforce becomes complex we use Apex.
Apex development Environment:
Apex entirely works on the force.com platform which consists of two users namely developer user and End user who performs two different sequences of action. The developer saves the code and the end user performs some action which invokes the apex code.
When a developer writes and saves apex code to the platform, the platform application server first complies the code into a set of instructions that can be understood by the apex runtime interpreter and then saves all those instructions as meta data in the data storage. All the uncompiled apex classes and triggers are compiled and stored in the data storage.
End user Action:
When an end user requests or triggers the execution of apex by either clicking on a button or accessing a visual force page the platform application server retrieves the compile instruction from the meta data which is your data storage and sends them through the runtime interpreter or apex runtime to the end user. All these happens with the help of the internet and in fraction of seconds so, the end user observes no difference in the execution time.
What are the different tools for writing Apex Code?
Force.com developer Console: It is a combined developer environment and collection of tools which we can use to create, debug and test the applications in our salesforce organization.
Force.com IDE: This is a plugin for Eclipse IDE which provides a unified interface for building and deploying Force.com applications.
Code Editor: The code editor in the salesforce user interface is where all classes and triggers are compiled when they are saved, and any syntax errors are flagged.
What is SOQL?
SOQL stands for Sales Object Query Language which is similar to that of SQL, but it is designed for salesforce data using same structure and keywords from SQL. You can query data from Salesforce using SOQL in
- Apex code
- Developer Console
- Salesforce REST and SOAP APIs
- Salesforce CLI
SOQL consists of Conditional expressions, Aggregate queries, GROUP BY and HAVING Clauses, Relationship Queries, Writing SOQL in Apex. SOQL allows you to perform a search operation on multiple objects at a time, search for text, email and phone fields from multiple objects.
What is the trigger?
In Triggering, when a special event occurs in Database it automatically invokes. Apex trigger validates you to execute custom activity before or after an event record in salesforce, such as insertions, updates, or deletions.
When should we use trigger?
- If we have a Complex logic which is incapable of being processed via declarative artifacts.
- If we have a logic. associated with DML.
- If we have operations on unrelated objects.
- If we have integration with External Systems.
REST API and Integration in Salesforce using REST API?
Representational State Transfer is a style of software architecture for distributed hypermedia systems. REST API has a lightweight request and response framework. REST API supports both XML and JSON. It is also applicable in Mobile and WEB apps. It is simple, easy to use and has a powerful web service based on the RESTful principle. It is easy to expose any functionality via REST resources and HTTP methods.
External service calling to Salesforce:
Standard REST API:
REST API allows updates on individual records
- Multiple calls for multiple updates
Custom REST API:
Expose Apex methods via REST
Create your own via REST
- Allows multiple updates in a single transaction.
What is Asynchronous Apex ?
To run your code asynchronously apex offers multiple ways. Some of the features of asynchronous apex are listed below:
Queueable apex: A queueable apex is used to start a long-running operation and get an ID for it to pass complex types of a job and chain jobs.
Scheduled Apex: For running an apex class on a specific schedule.
Batch Apex: Jobs like database maintenance need to be executed in batches as they are Long running jobs which have large data volumes and for the jobs which need huge query results than regular transactions allow.
What are the features of Apex?
Apex can be Integrated:
Apex has built in support for DML operations like INSERT, UPDATE, DELETE and also DML exception handling. Salesforce objects are nothing but the accounts, contacts and leads that you have. Salesforce objects involve performing queries using SOQL (salesforce query language) and SOSL (salesforce object search language) in apex. It also supports custom public API calls that can be built from stored apex methods.
Easy To Use:
Apex is based on familiar java expressions such as variable and expression syntax, block and conditional statement syntax, lop syntax, object and array notation. Apex syntax and semantics are easy to understand and it encourages the efficient use of lightning platform. Therefore, Apex codes are both briefly and clearly understood, and easy to write. Salesforce apex is easy to test, provides built-in support for unit test creation and execution. It includes test results to indicate how much of the code is covered and which part of your code could be more efficient.
Most of the operations in Apex are based on data and database. It is designed to execute multiple queries and DML statements together on the database. Database is a place where all the data is stored. So, developers can use the database source procedures to combine multiple transaction statements on a database server.
Salesforce runs in a multi-tenant environment as it has a common database which is used by multiple users, they store all the data and records in the shared database itself. The apex runtime engine is used to cut closely against the runway code which prevents from monopolizing shared resources, which means it does not allow any single user to use more of the database than the other user. All the users get equal access to the database.
When to code using Apex?
Apex can be used to create web services that integrate salesforce with other applications. You can Integrate salesforce with third-party application using APIs, creating of email services for email setup and to implement functionality that can’t be implemented using existing workflows and process builder functionality. Workflow rules and process builder operations sometimes have featured limitations that can be overcome with apex. Pulling information from an external system can be done through apex and not by workflow logic and process builders.Salesforce consists of new interface called Salesforce Lightning
Conclusion for Salesforce Apex Training:
Apex can be used to perform complex validation over multiple objects. You can create customer transaction logic which occurs over entire transaction and not just a single recorder object.Ides Trainings provides you with cost-effective services.
