1 Technical Update COURSE CODE: COURSE TITLE: LEVEL: AUDIENCE: SQSDBE SQL Server 2012 Database Engine Technical Update Beginner-to-intermediate SQL Server DBAs and/or system administrators PREREQUISITES: At least six (6) months DBA experience with SQL Server 2005/2008. DURATION: SUMMARY: OBJECTIVES: 2 days Focusing on the SQL Server 2012 database engine, this course discusses the many fundamental changes in SQL Server 2012 s architecture and structure. The key improvement that enhances scalability, application, continuous availability and performance are central and illustrated via usage examples: Configuration Memory management Contained databases Big data Columnstore indexes SSIS catalog Deprecated features DB checkpoints T-SQL Etc. Upon completion of this presentation, the participant should have a working knowledge of the Core Topics that follow.

2 1. SQL SERVER CONFIGURAITON OPTIONS Via SSMS Via Stored procedures How to display configuration values 2. MEMORY MANAGEMENT CHANGES Prior to SQL 2012 vs. new Max server memory Relevant DMVs DBCC memory status output AWE 3. SQL DATA MAXIMUM CAPACITY Database objects Utility objects Application objects Replication objects 4. NEW DYNAMIC MANAGEMENT VIEWS (DMVs) In SQL 2012; not in SQL 2008 In SQL 2008; not in SQL 2012 DMV columns in 2012; not in SQL 2008 DMV columns in 2008; not in 2012 Operating system info: SELECT * FROM sys.dm_os_windows_info 5. SCALABILITY & PERFORMANCE On-line index rebuild Increased number of partitions supported Metadata location TempDB performance enhancements TempDB DMV enhancement Diagnostic information queries New DMVs Automatic execution of queries at start-up Online index rebuild (VARCHAR(MAX)) 6. CONTAINED DATABASES Definition Usage case Terms Components Contents How-to-create

3 7. BIG DATA PROCESSING Hadoop technology defined Unconventional data types (e.g., non-relational data types: web logs, , etc.) Hadoop and business intelligence implications Data explorer tools 8. SQL SERVER 2012 VERSIONS Name Scope and limits 9. DATA COLLECTOR Purpose Terminology Tasks Management Data Warehouse 10. COLUMNSTORE INDEXES Usage cases Compared to B-tree index How to create Data types supported Restrictions and limitations Bitmap filter implications Partition table considerations Query optimization Best practices 11. SQL SERVER DATA TOOLS (SSDT) Purpose and scope Architecture Installation requirements and system requirements Auto script generation Debug stored procedures 12. REPLICATION Publisher failover Extended events 13. SECURITY ENHANCEMENTS New permissions New role management Default schema for groups Audit enhancements Contained DB considerations

4 14. LINKED SERVERS Usage cases Security How to create Distributed queries 15. DATA TYPES, PER: Column Local variable Expression 16. T-SQL RELATED Sequences First-value; last-value Sequences vs. identity columns Offset/fetch Throw in error handling Business key vs. surrogate key Ad-hoc query paging Breakpoints and debugging LAG OVER LEAD 17. MANAGEABILITY ENHANCEMENTS SQL Server management Studio: e.g., debugging Start-up options Windows PowerShell Database Engine Tuning Advisor SSMS shortcuts SSMS DB Engine Query Editor debugging Indirect checkpoints 18. SSIS CATALOG (SSISDB) Purpose Object hierarchy Folders Projects and packages Parameters Environment, environment variables and environment references Executions Validations Permissions

5 19. PERFORMANCE MONITOR & TUNING TOOLS Traces Distributed replay System monitor SSMS Error logs System stored procedures DBCC Built-in functions Trace logs Execution plans SQL Profiler Dynamic Management Views (DMVs) 20. DEPRECATED FEATURES & REPLACEMENT, IF APPLICABLE 21. BACKWARD COMPATIBLE FEATURES 22. HIGH AVAILABILITY & DISASTER RECOVERY Availability groups vs. mirrors Failover modes Replicas Modes 23. FILETABLE Uses Contents Maintenance 24. DB CHECKPOINTS Definition Automatic Indirect Manual Interval 25. SQL SERVER 2012 HARDWARE/SOFTWARE REQUIREMENTS Components (e.g., hard drives) Processor Memory Operating system

6 26. TEMPDB ENHANCEMENTS Collation of calling DB vs. collation of instance Contained DB implications 27. CLOUD COMPUTING Definition and scope Layers Deployment models Architecture Some typical uses
