Overview of this book

As applications built on the Salesforce platform are now a key part of many organizations, developers are shifting focus to Apex, Salesforce’s proprietary programming language. As a Salesforce developer, it is important to understand the range of tools at your disposal, how and when to use them, and best practices for working with Apex. Mastering Apex Programming will help you explore the advanced features of Apex programming and guide you in delivering robust solutions that scale. This book starts by taking you through common Apex mistakes, debugging, exception handling, and testing. You'll then discover different asynchronous Apex programming options and develop custom Apex REST web services. The book shows you how to define and utilize Batch Apex, Queueable Apex, and Scheduled Apex using common scenarios before teaching you how to define, publish, and consume platform events and RESTful endpoints with Apex. Finally, you'll learn how to profile and improve the performance of your Apex application, including architecture trade-offs. With code examples used to facilitate discussion throughout, by the end of the book, you'll have developed the skills needed to build robust and scalable applications in Apex.

Summary

In this chapter, we have focused on the many ways in which we can ensure that we are maintaining the security of our application via our Apex code.

Trust has always been Salesforce's number-one value. As an organization, handling hundreds of billions of daily transactions with hundreds of thousands of customer storing their data, they have to make sure that you can be confident that they will not put your data at risk. As a part of that agreement, however, we as developers have to ensure that we are not accidentally exposing data or allowing users to access more data than they should be able to.

We started the chapter by looking at how sharing and permissions are managed on Salesforce before reviewing how we can enforce them within our Apex code, then looking at how we can create and manage custom sharing setups using Apex-managed sharing.

Following this, we moved to the other side of the Salesforce access control model, object, and field permissions. We saw...
