What is SQL Server Express edition?

SQL Express is a free and feature-limited edition of SQL Server that has been being published since the SQL Server 2005 version and it still continues to be published by Microsoft. Nowadays, Microsoft has released the Express edition of SQL Server 2019. We can use this edition for lightweight data-driven mobile, desktop or web applications. However, when we decide to use this edition, the supported features have to be checked in the Editions and supported features of SQL Server 2019. For example, the database size can not exceed 10 GB and the SQL Server Agent feature is not supported by the Express editions. As a result, we must take the limited features into consideration before planning to use the SQL Express Editions.

In this article, we will learn how to install SQL Server 2019 Express edition step by step, and we will also mention some useful tips for the installation.
