SQL Server 2019 is offered in two main commercial editions to accommodate the unique feature, performance and price requirements of organizations and individuals:

• Enterprise Edition is ideal for applications requiring mission critical in-memory performance, security and high availability.
• Standard edition delivers fully featured database capabilities for mid-tier applications and data marts.

The editions are offered in a straightforward, tiered model that creates greater consistency across the product editions, features and licensing. Enterprise Edition includes all the capabilities available in SQL Server 2019.

Through a consistent programming interface across all editions, it is easier than ever for developers and partners to build and upgrade applications that take advantage of advanced performance, security, and data mart or data warehouse features – regardless of scale, from Express to Enterprise.
