Additionally, you can <\/span><b>implement sophisticated business rules<\/b><span style=\"font-weight: 400;\"> that would be infeasible with <\/span><b>&#8220;point and click&#8221; tools<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><p><span style=\"font-weight: 400;\">For instance, you can <\/span><b>query the Salesforce database using SOQL<\/b><span style=\"font-weight: 400;\"> to verify a specific record&#8217;s existence before taking action. It&#8217;s also feasible to <\/span><b>handle specific exceptions<\/b><span style=\"font-weight: 400;\"> to foresee errors. Consequently, it&#8217;s an invaluable asset for managing intricate business logics.<\/span><\/p><p><span style=\"font-weight: 400;\">Another standout feature: Apex enables integration with third-party services via <\/span><b>HTTP calls<\/b><span style=\"font-weight: 400;\"> and <\/span><b>RESTful classes<\/b><span style=\"font-weight: 400;\">.

To avoid pitfalls, some best practices should be kept in mind.<\/span><\/p><p><span style=\"font-weight: 400;\">Firstly, be aware that it is restricted by <\/span><b>governor limits<\/b><span style=\"font-weight: 400;\"> to maintain platform performance. For instance, there is a <\/span><b>maximum number of SOQL queries or<\/b> <a href=\"https:\/\/datascientest.com\/en\/all-about-data-manipulation-language\"><span style=\"font-weight: 400;\">DML<\/span><\/a><span style=\"font-weight: 400;\"> per transaction. These limits safeguard other users from potentially resource-intensive code. For effective development, you must <\/span><b>recognize and comply with these limits<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><p><span style=\"font-weight: 400;\">Additionally, for security, data access should always <\/span><b>comply with sharing rules defined in Salesforce<\/b><span style=\"font-weight: 400;\">. This necessitates that Apex code check <\/span><b>user permissions<\/b><span style=\"font-weight: 400;\"> and apply all suitable <\/span><b>access controls<\/b><span style=\"font-weight: 400;\"> (using with sharing, for example). This vigilance ensures application consistency and security.<\/span><\/p><p><span style=\"font-weight: 400;\">Another crucial aspect: code quality. To withstand the test of time, Apex code must be well-written. <\/span><b>Bulkification<\/b><span style=\"font-weight: 400;\"> (writing code to handle batches of records) prevents errors during imports or bulk operations.<\/span><\/p><p><span style=\"font-weight: 400;\">Similarly, <\/span><b>separating triggers from business logic<\/b><span style=\"font-weight: 400;\"> (using utility classes) allows for better maintenance and easier reusability. To maximize performance and scalability, you can also <\/span><b>minimize database call frequency, prioritize optimized queries, and limit heavy processing<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><p><span style=\"font-weight: 400;\">All these tips ensure <\/span><b>fast, stable, and scalable code<\/b><span style=\"font-weight: 400;\">. They should become second nature when developing with Apex!<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-fa1262f elementor-widget elementor-widget-image\" data-id=\"fa1262f\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"1536\" height=\"1024\" src=\"https:\/\/datascientest.com\/en\/files\/2025\/07\/developpeur-salesforce-apex-debugging.webp\" class=\"attachment-full size-full wp-image-197917\" alt=\"\" srcset=\"https:\/\/datascientest.com\/en\/files\/2025\/07\/developpeur-salesforce-apex-debugging.webp 1536w, https:\/\/datascientest.com\/en\/files\/2025\/07\/developpeur-salesforce-apex-debugging-300x200.webp 300w, https:\/\/datascientest.com\/en\/files\/2025\/07\/developpeur-salesforce-apex-debugging-1024x683.webp 1024w, https:\/\/datascientest.com\/en\/files\/2025\/07\/developpeur-salesforce-apex-debugging-768x512.webp 768w\" sizes=\"(max-width: 1536px) 100vw, 1536px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-8157be4 e-flex e-con-boxed e-con\" data-id=\"8157be4\" data-element_type=\"container\" data-settings=\"{&quot;content_width&quot;:&quot;boxed&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-bc0146c elementor-widget elementor-widget-heading\" data-id=\"bc0146c\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-xl\">Transform from a simple user into a CRM experience creator<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8a36556 elementor-widget elementor-widget-text-editor\" data-id=\"8a36556\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">Thanks to its object-oriented syntax, triggers, classes, and seamless integration with the Salesforce ecosystem, Apex empowers you to <\/span><b>transform the CRM platform into a bespoke tool<\/b><span style=\"font-weight: 400;\">, perfectly aligned with business needs.<\/span><\/p><p><span style=\"font-weight: 400;\">It elevates Salesforce to new heights in customization and efficiency.
