### Beginner's Guide to Creating Your First Apex Class Welcome to your first step into the world of Apex! In this tutorial, we'll guide you through creating a simple Apex class. Apex is a strongly-typed, object-oriented programming language used in Salesforce, and it's similar to Java. Don't worry if you're new to coding—we'll keep it straightforward. #### Step 1: Access Salesforce Developer Console 1. **Log in to Salesforce**: Use your Salesforce credentials to log in to your Salesforce instance. 2. **Open Developer Console**: Click on the gear icon (⚙️) in the upper right corner of Salesforce and select **Developer Console**. #### Step 2: Create a New Apex Class 1. **Open the Apex Class creation window**:    - In the Developer Console, go to the top menu and click on **File** > **New** > **Apex Class**. 2. **Name your class**:    - A prompt will appear asking you to name your class. Enter a simple name like `HelloWorld` and click **OK**. #### Step 3: Wri

Salesforce has an inherent limitation - it is unable to create rollup summaries on objects linked through a simple lookup relationship, as opposed to the standard master-detail relationship.  This is where the Declarative Lookup Rollup Summaries (DLRS) tool comes into play. DLRS is a community-driven, open-source tool that enables users to create rollup summaries between objects that are related via lookup relationships. It is especially valuable for Salesforce administrators and developers who need to calculate aggregate data across these relationships without writing complex Apex code. #### What is a Lookup Rollup Summary? In Salesforce, a rollup summary field is a type of field that calculates the sum, minimum, maximum, or average of a numeric field on a related object, or counts the number of records related to a parent object. Rollup summaries are straightforward to implement on master-detail relationships. However, for lookup relationships, Salesforce does not natively support ro

One area where Salesforce truly shines is in the ability to leverage Apex instead of Flows for more complex and efficient solutions. Let’s explore why you might choose Apex over Flows and how to implement it effectively. #### Why Choose Apex Over Flows? **1. **Greater Control and Flexibility**: While Flows are user-friendly and great for simple automation, Apex provides more granular control over your processes. With Apex, you can handle complex business logic that Flows might struggle with, such as handling bulk records or integrating with external systems. **2. **Performance**: Apex is optimized for performance. In scenarios where efficiency is critical, such as processing large volumes of data, Apex can be more reliable and faster than Flows. **3. **Error Handling**: Apex offers robust error handling mechanisms. You can write custom error messages and handle exceptions more gracefully compared to Flows, which can sometimes fail silently or provide limited troubleshooting information
