Microsoft SQL Server 2019 Standard - 2 Core license for Windows
This license allows for an unlimited number of users and devices to be connected to a server. If you want to install your SQL servers under a Core Based License, make sure you can follow these rules: You need to license every physical operating system environment (OSE) that is running SQL server software.
The 2019 version includes many new features or improvements of features from previous product releases. For example, the new in-memory OLTP module provides up to 30 times faster applications and up to 100 times faster data queries.
The safety functions have also been significantly improved. The database management system has been designed for a hybrid environment, which means you can use it both locally and in the cloud. With the cloud service, you can store all your data so that you can recover it even in an emergency.
