Some failures, though, are related to human error and you might wish to recover the system to a point before that error. The point-in-time recovery features of SQL Server 2016 can help you to achieve this. Because they are typically much larger, user databases are more likely to be affected by system failures than system databases.

When configuring security for your Microsoft SQL Server systems, you should ensure that you meet any of your organisation’s compliance requirements for data protection. Organisations often need to adhere to industry-specific compliance policies, which mandate auditing of all data access. To address this requirement, SQL Server provides a range of options for implementing auditing. Another common compliance requirement is the encryption of data to protect against unauthorised access in the event that access to the database files is compromised.

- Humans have a long history of working with data in different forms, from storing various records of yielded crops to game hunting and other information relevant to early civilisations.
- Solutions to these problems brought about the basic principles of the database systems we use today.
- This new release’s basic concepts cater to the increased need for data mining and machine learning services in structured query languages used for databases.
- You must, however, ensure that you have a clear plan of how to proceed and successfully recover the database to the required state.
SQL Server supports this requirement by providing transparent data encryption (TDE). To reduce the risk of information leakage by users with administrative access to a database, columns containing sensitive data—such as credit card numbers or national identity numbers—can be encrypted using the Always Encrypted feature. This module describes the available options for auditing in SQL Server, how to use and manage the SQL Server Audit feature, and how to implement encryption. The tools provided by Microsoft SQL Server make administration easy when compared to some other database engines. However, even when tasks are easy to perform, it is common to have to repeat a task many times. This can help to avoid situations where an administrator forgets to execute a task at the required time.
