SQLServer 2012 Features...

SQL 2012 Features:

1.Contained Database Authentication:

Contained Database Authentication increases compliance by allowing users to be authenticated directly into user databases without logins. User information for login (username and password) is not stored inside master database but user databases directly. It is very secure because users can only perform DML operations inside the user databases and not database instance level operations. It also reduces the need to login to the database instance and avoid orphaned or unused logins in the database instance. This feature is used in AlwaysOn to facilitate better portability of user databases among servers in the case of server failover without the need to configure logins for all database servers in the cluster. 72.Database Recovery Advisor:

This feature has introduced significant user experience enhancements to the ways DBAs can now restore databases using SQL Server Management Studio. Capabilities include a visual timeline that presents the backup history of the database and the available points in time to which the user can restore the database, algorithms to streamline identifying the right sets of backup media to get the database back to a specific point in time, and page restore dialog in SSMS to do page-level restores of the database.

3.Table Partitioning up to 15,000

Support growing data warehousing with table partitioning that now scales to 15,000 partitions. This new expanded support helps enable large sliding-window scenarios which will streamline maintenance of large sets within filegroups that need data switched in and out per the needs of the data warehouse. 6

4.Full-Text Search Performance Overhaul

FTS in SQL Server Code Name ―Denali‖ brings magnitudes of performance and scale advances with significantly improved query execution and concurrent index update mechanisms. Full-text search now includes properties scoped searches without requiring developers to maintain file properties (such as Author Name, Title, etc…) separately in the database. Developers can now also benefit with improved NEAR operator that allows them to specify distance in-between as well as the order of words. In addition to these exciting changes, Full-text Search has revamped all language word-breakers to latest Microsoft editions and includes support for two more languages in Czech and Greek.

5.SQL Server AlwaysOn

The new integrated high availability and disaster recovery solution provides redundancy within a datacenter and across datacenters to help enable fast application failover during planned and unplanned downtime. AlwaysOn delivers a suite of new capabilities

 SQL Server AlwaysOn Availability Groups is a new feature that greatly enhances the capabilities of Database Mirroring and helps ensure availability of application databases. Availability Groups provides an integrated set of options including automatic and manual failover of a group of databases, support for up to four secondaries, fast application failover and automatic page repair.

 SQL Server AlwaysOn Failover Cluster Instances enhance SQL Server Failover Clustering and support multi-site clustering across subnet which helps enable cross-datacenter failover of SQL Server instances. Fast and predictable instance failover is another key benefit which helps ensure fast application recovery.

 SQL Server AlwaysOn Active Secondries enable secondary instances to be utilized for running report queries and backup operations which helps eliminate idle hardware and improve resource utilization.

 SQL Server AlwaysOn Connection Director Capabilities:

o Multi-subnet failover: This improvement enables faster client connection failover for AlwaysOn in multi-subnet scenarios. Now client applications can failover across multiple subnets (up to 64) almost as fast as they can failover within a single subnet.

o Read-Only Intent: This improvement is a big step in our connectivity story for Readable secondaries, which is accepted really well by our customers, both at PASS as well as earlier SDRs. This improvement gives the customers a way to control the type of workloads that run on their HA servers and efficiently manage their resources.

 SQL Server AlwaysOn AutoStat auto-creates and updates temporary statistics needed for queries running on the readable secondary. These temporary statistics area stored in TempDB therefore no physical changes are required in the user database. This allows the optimizer to generate optimal query plans on secondary replica as it would do on the primary replica and it does not require any user intervention.

6.Audit Enhancements

Enhancements to SQL Server auditing capabilities bring added flexibility and usability for auditing across the SQL Server environment, help making it even easier for organizations to meet compliance policies.

 SQL Audit for all editions allows organizations to expand the benefits of SQL Server Audit from Enterprise edition to all editions for more thorough auditing practices across SQL Server databases enabling audit standardization, better performance and richer features.

 User-Defined Audit allows the application to write custom events into the audit log to allow more flexibility to store audit information.

 Audit Filtering provides greater flexibility to filter unwanted events into an audit log.

 Audit Resilience delivers the ability to recover auditing data from temporary file and network issues.

7.Default Schema for Windows Groups:

Database schema can now be tied to Windows Group rather than individual users to increase database compliance. It eases administration of database schema, decreases the complexity of database schema management through individual Windows users, prevent errors of assigning schema to the wrong users when users changes groups, avoids unnecessary implicit schema creation, and greatly reduces the chance of query errors when wrong schema being used.

8.User-Defined Server Roles:

User-Defined Server Roles increase flexibility, manageability, and facilitate compliance towards better separation of duties. It allows creation of new server roles to suit different organizations that separate multiple administrators according to roles. Roles can also be nested to allow more flexibility in mapping to hierarchical structures in organizations. It also helps prevent organizations to use sysadmin for database administration.

9.Distributed Replay

Simplify application testing and minimize errors with application changes, configuration changes, and upgrades using new Distributed Replay. This multi-threaded replay utility provides the ability to simulate production workload scenarios testing after upgrade or configuration changes ultimately leading to protected performance during changes.

10.Windows Server Core Support

SQL Server is supported on Windows Server Core. By running SQL Server on Windows Server Core the OS patching can be reduced significantly which greatly reduces planned downtime. †The percentage reduction in patching and OS reboots can be as much as 50-60% in certain environments depending on the server roles that are enabled and the type of patches that are applied. 5

11. Column Store Index (“Apollo”)

―Apollo‖ introduces column store technology to the database engine, making SQL Server the first of the major general-purpose database systems to have a true column store. Apollo brings together the VertiPaq technology that was developed in Analysis Services (and is the crucial foundation for PowerPivot) and a new query execution paradigm called batch processing to provide truly astonishing speed up for common data warehouse queries. In test scenarios customers have experienced approximately 100x improvements in star join and similar queries.
