Salesforce Apex Vs flow.

Introduction:

An Overview of Apex and Flows:

In Salesforce, two powerful tools stand out for their ability to enhance and streamline business processes, where the apex and flow come from. Apex is a robust, strongly typed programming language that allows developers to execute the flow and transactions within the Salesforce governer limits to perform business logic for most system events, including calls with API. It enables developers to perform business logic for most system events, including button and click events, related record inserts, updates, and Visualforce pages. On the other hand, Flow, also known as Salesforce Flow, is a declarative automation tool that empowers users to build complex business solutions without writing codes. It provides a user-friendly interface for creating automated processes, including data updates, email alerts, and task assignments.

History of Salesforce Apex and Flow:

Salesforce introduced Apex in 2006 as a Java-like programming language specifically designed to enhance the Salesforce Platform. Its creation marked a significant milestone, providing developers with the ability to write code that runs on Salesforce servers, which allowed for custom business logic and integration that were previously unattainable.

Flow, initially launched as Visual Workflow in 2010, aimed to provide a more accessible way for users to automate business processes. Unlike Apex, Flow was designed to be used by non-developers, offering a drag-and-drop interface to create complex workflows. Over time, it evolved into Salesforce Flow, encompassing various automation tools such as Process Builder and Flow Builder.

The difference between Salesforce Apex Vs flow .

What is Salesforce Apex?

Apex is a powerful, strongly typed, object-oriented programming language for developers working within the Salesforce environment. It enables the creation of complex business logic that can be executed on Salesforce servers. Apex requires coding knowledge to implement a business solution. Apex without code coverage: 75 percent in testing, it cannot be deployed from the sandbox to production.

Key Functionalities of Apex:

• Triggers: Apex triggers allow developers to execute custom actions before or after changes to Salesforce records, such as insertions, updates, or deletions.

• Classes and Methods: Developers can create reusable code blocks using classes and methods, enabling modular and maintainable code.

• Batch Processing: Apex supports batch processing, which allows for the processing of large volumes of records asynchronously, thus improving performance and scalability.

• Integration: Apex can call external web services and APIs, facilitating integration with third-party systems and services.

• Asynchronous Processing: With features like future methods, queueable Apex, and scheduled Apex, developers can handle long-running operations and execute them asynchronously.

What is Salesforce Flow?

Flow is a declarative tool designed for users who can implement simple business logic without coding knowledge. You do not need a developer, instead of an admin, any user can do it. Salesforce Flow allows users to easily update and adjust their workflows as needed, making it a flexible option.

Key Functionalities of Flow:

• Flow Builder: The primary interface for creating flows, it allows users to design automation by dragging and dropping elements like screens, actions, and decisions.

• Data Manipulation: Flows can create, update, delete, and retrieve Salesforce records, enabling comprehensive data management.

• Guided Processes: Flow can create interactive, guided processes for users, such as wizard-like interfaces that collect information and perform actions based on user input.

• Process Automation: Flow automates routine tasks such as sending emails, posting to Chatter, and assigning tasks, reducing the need for manual intervention.

Types of flows :

• Screen Flow: It guides users through a business process that’s launched from Lightning pages, Experience Cloud sites, quick actions, and more.

• Record Triggered Flow:  It launches when a record is created, updated, or deleted. This auto-launched flow runs in the background.

• Scheduled Triggered Flow: It launches at a specified time and frequency for each record in a batch. This auto-launched flow runs in the background.

• Platform Event—Triggered Flow: It launches when a platform event message is received. This auto-launched flow runs in the background.

• Autolaunched Flow (No Trigger): It launches when invoked by Apex, processes, the REST API, and more. This auto-launched flow runs in the background.

• Record-Triggered Orchestration: It launches when a record is created or updated. An orchestration lets you create a multi-step, multi-user process.

Advantages of Flow:

· It can handle complicated queries in the Salesforce flow.

·We can schedule a batch class from the Salesforce flow.

·We can use the Schedule path to execute a code at a specific time from the record- triggered flow.

·You don't need to write a test class in the Salesforce flow.

·Debugging becomes possible.

Disadvantages of Flow:

· We cannot implement error alerts in record-triggered flows.

· It can be a time-consuming process.
