2. PowerPivot for Excel: Enables users to create advanced analytics and data models within Excel.
3. StreamInsight: A complex event processing engine for real-time analysis of streaming data.
4. SharePoint integration: Enhanced support for integrating with SharePoint 2010.
5. Data-tier Application (DAC) Framework: Facilitates the packaging, deployment, and updating of database applications.
6. Improved performance and scalability: Optimizations for better performance and handling of large databases.
7. SQL Azure Integration: Better support for cloud-based database services.
8. Policy-Based Management: Simplifies administration through policy-based rules and conditions.
9. Enhanced security features: Including data encryption, auditing, and role-based access control.
However, SQL Server 2008 R2 has reached its end-of-life (EOL), with extended support ending on July 9, 2019. This means Microsoft no longer provides technical support, bug fixes, or security updates, making it vulnerable to potential security risks. It is recommended to upgrade to a newer version like SQL Server 2016 or later for better performance, security, and features.
