- Row-level security: Row-level security allows businesses to control access to data at the row level. This means that businesses can grant different users access to different rows of data, based on their job function or role.
- Dynamic data masking: Dynamic data masking allows businesses to mask sensitive data from unauthorized users. This means that businesses can protect sensitive data from being exposed, even if it is accessed by an unauthorized user.
- Audit and compliance: SQL 2017 includes a number of features that help businesses to audit and comply with data protection regulations. These features include audit logs, which track all changes to the database, and compliance reports, which help businesses to demonstrate compliance with data protection regulations.
Overall, the new security features in SQL 2017 make it a more secure choice for businesses that need to protect sensitive data.
Scalability
The scalability of SQL 2017 is a key factor in its ability to meet the demands of modern businesses. SQL 2017 can be scaled to support databases of any size, from small departmental databases to large enterprise-wide databases with hundreds of terabytes of data.
- Horizontal scaling: SQL 2017 can be scaled horizontally by adding more servers to the database cluster. This allows businesses to increase the capacity of their database without having to upgrade to a more expensive hardware platform.
- Vertical scaling: SQL 2017 can also be scaled vertically by adding more memory or CPUs to the database servers. This allows businesses to increase the performance of their database without having to add more servers to the cluster.
The scalability of SQL 2017 makes it a good choice for businesses that need to manage and analyze large amounts of data. SQL 2017 can be scaled to meet the demands of even the most demanding workloads.
Availability
High availability is a critical requirement for many businesses. SQL 2017 includes a number of features that help to ensure high availability, making it a good choice for businesses that need to keep their databases up and running 24/7.
- Always On Availability Groups: Always On Availability Groups is a feature in SQL 2017 that allows businesses to create a group of failover servers. If the primary server in the group fails, one of the failover servers will automatically take over, ensuring that the database remains available.
- Failover Clustering: Failover clustering is a feature in SQL 2017 that allows businesses to create a cluster of servers. If one of the servers in the cluster fails, the other servers in the cluster will automatically take over, ensuring that the database remains available.
- Database Mirroring: Database mirroring is a feature in SQL 2017 that allows businesses to create a mirror copy of their database on a separate server. If the primary database fails, the mirror database can be used to ensure that the database remains available.
- Log Shipping: Log shipping is a feature in SQL 2017 that allows businesses to ship transaction logs from the primary database to a secondary database. If the primary database fails, the secondary database can be used to recover the data.
Overall, the high availability features in SQL 2017 make it a good choice for businesses that need to keep their databases up and running 24/7.
Ease of use
SQL 2017 is designed to be easy to use, with a number of features that simplify administration and management. This makes it a good choice for businesses that do not have a dedicated database administrator or that have limited IT resources.
- Simplified administration: SQL 2017 includes a number of features that simplify administration, such as a graphical user interface (GUI) for managing the database and a number of wizards and templates that can be used to create and manage databases and objects. This makes it easy for even non-technical users to administer SQL 2017.
