Additionally, maintaining logs of user access is essential for monitoring and identifying any unauthorized attempts at data access.<\/span><\/p>\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-b9d44a1 e-flex e-con-boxed e-con\" data-id=\"b9d44a1\" 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-3f83225 elementor-widget elementor-widget-heading\" data-id=\"3f83225\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Conclusion<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-12716eb elementor-widget elementor-widget-text-editor\" data-id=\"12716eb\" 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;\">The <\/span><b>Data Control Language (DCL)<\/b><span style=\"font-weight: 400;\"> is indispensable for managing access and ensuring the security of <\/span><b>databases<\/b><span style=\"font-weight: 400;\">.
