Relational Database Management System Security Features
Microsoft SQL Server 2019 is a relational database management system (RDBMS) that offers enhanced security features. These features help protect your data from unauthorized access and ensure that only authorized users can access it.
Some of the security features available in Microsoft SQL Server 2019 include:
- Role-based security: This feature allows you to control data access based on users' roles within your organization. For example, you can grant managers read-only access to specific data while allowing full read/write access for employees.
- Data encryption: SQL Server 2019 uses industry-standard encryption algorithms to protect your data at rest and in transit. This ensures that only authorized users can view or modify your data.
- Audit logging: SQL Server 2019 automatically tracks changes made to your data. This allows you to see who accessed or modified your data and when they did it.
- User-defined security: You can create custom security policies to further control access to your data. For example, you can allow only certain users to access sensitive data or restrict access to specific data based on the user's location.
- Multi-factor authentication: SQL Server 2019 supports multi-factor authentication, which requires users to provide more than one form of identification before being granted access to data. This provides an extra layer of protection against unauthorized access.
Microsoft SQL Server 2019 provides a comprehensive set of security features that can help you protect your data from unauthorized access. By using these features, you can control who can access your data and what they can do with it. This can help keep your data safe and ensure that only authorized users can view or modify it.
Replication Features
SQL Server 2019 provides several new replication features to help you manage your data more effectively. For example, the new cross-database replication feature allows you to replicate data between databases on different servers, making it easier to keep your data synchronized.
The updated conflict detection and resolution feature help ensure that data is replicated accurately between servers. Finally, the new snapshot isolation feature helps improve performance by allowing replicas to work with a consistent data view.
There are several different types of replications that you can configure in SQL Server, each with its own set of features and benefits:
- Transactional Replication: This replication copies transactions from a source database and applies them to a destination database. It is typically used to replicate data from a production database to a reporting database or to distribute data across multiple servers. Transactional replication supports push and pull subscriptions and can be configured to run continuously or on a schedule.
- Merge Replication: This replication copies data from a source database and applies it to a destination database. It also allows changes to be made at the destination database and replicated back to the source.
Merge replication is typically used in scenarios where data needs to be synchronized between multiple databases and servers or when users need to be able to make changes offline and have those changes replicated when they reconnect.
- Snapshot Replication: This type of replication copies the entire contents of a source database to a destination database at regular intervals. It is typically used in scenarios where data does not change frequently or when you need an initial copy of data that can be used for reporting or testing purposes. Snapshot replication does not support updates, so any changes that are made at the destination database will not be replicated back to the source.
- Transactional & Merge Replication with BI Tools: This type of replication is a combination of transactional and merge replication, with added support for reporting and analysis tools such as Power BI and SQL Server Reporting Services (SSRS). It is typically used in scenarios where you need to replicate data from a production database to a reporting database. It also allows users to make changes offline and have those changes replicated when they reconnect.
