Lista de características de Katmai – SQL SERVER 2008

Para quienes se preguntan cuáles son las nuevas características de SQL Server 2008.

Security/Auditing
     – Transparent Data Encryption (encryption while data is ‘still’ on disk, transparent to applications)
     – External Key Management (Consolidation of key management, integration with external products)
     – Data Auditing (1st-class ‘AUDIT’ objects; DDL support; audit objects, principals, data, etc.; support for multiple logging targets)
  Availability/Reliability
     – Pluggable CPU support
     – Enhanced Database Mirroring (compression of mirror streams, enhanced performance, automatic page-level repair for principal/mirror)
  Performance
     – Data compression (easy to enable/disable online, more efficient data storage (this is NOT traditional data compression))
     – Backup stream compression (server level control or backup statement control, all backup types)
     – Performance data collection (single, common framework for data collection, reporting, and storage/warehousing)
     – Improved Plan Guide support (plan freezing, pull plans directly from plan cache, SSMS integration, etc.)
     – Resource Governor (create pools and groups to govern, define classifications based on built-in functions, segment resource utilization amoung groups)
  Management
     – Policy-based management framework (manage via policies vs. scripts, enterprise-wide support, automated monitoring/enforcement, etc.)
     – Integrate with Microsoft System Center
     – Extended Events (high perf lightweight tracing infrastructure, NOT sql trace, integrated with ETW, unprecidented insight into goings-on)
  Development Enhancements
     – Improved datetime datatypes (100th nanosecond precision (7 digits past second), time-zone datetime offset, date only, time only)
     – HierarchyID datatype (hierarchical-aware data type, ORDPath values, built-in functions, methods, etc.)
     – Entity Data Model support (develop ‘business entities’ vs. tables, model complex relationships, retrieve entities vs. rows/columns)
     – LINQ
     – Sql Server Change Tracking (Change Data Capture, get ‘diff’ data changes WITHOUT a comparible value (i.e. datetime, timestamp, etc.))
     – Table Valued Parameters
     – MERGE statement (‘upsert’ data, also includes deletion functionality)
     – Large UDT’s (no more 8000 byte limit on CLR-based UDTs, no more 8000 byte limit for UDA’s)
     – Spatial data (GEOMETRY and GEOGRAPHY data types, built-in spatial function support, spatial indexes)
     – XML enhancements (support for lax validation, office 12 support, xs:dateTime support, lists/union types, LET FLOWR support, etc.)
     – Inline initialization and compound assignment
  Service Broker
     – New UI and Tools for working with (add/drop/edit functionality within SSMS, Diag tools, )
     – Conversation Priority (set message ordering, send/receive impact, 1-10 levels)
  Data Storage
     – Data compression (see above)
     – FILESTREAM attribute (get the ‘best of both’ functionality from BLOBs in the DB vs. BLOBs on filesystem, no more “to blob or not to blob”)
     – Integrated Full Text Search (FTS fully integrated into DB engine, no external storage, no external service, more efficient and reliable costing)
     – Sparse columns (more efficient storage for ‘wide’ tables with many columns that repeat and don’t contain data)
     – New index types (spatial indexes, hierarchical indexes, FILTERED indexes (indexes on filtered values within columns), etc.)
  Data Warehousing/ETL
     – Partitioned Table Parallelism (no more thread limit per partition)
     – Star Join support (no special syntax, optimizer based, full backward syntax support)
     – Data compression (see above)
     – Resource Governor (see above)
     – Persistent Lookups in SSIS (no more re-querying for lookup operators, cache lookups in multiple ways, persist lookups to disk)
     – Improved thread scheduling in SSIS (shared thread pool, pipeline parallelism)
     – Change Data Capture (see above)
     – MERGE statement (see above, great uses with slowly changing dimensions)
     – Scale-out analysis services (read-only storage supports multiple AS servers)
     – Subspace computations
     – New Tools for Cube design
     – Best Practice Design Alerting
     – Backup cubes with better scalability
     – Data-mining add-ins for Excell
  Reporting
     – IIS Agnostic Reporting Services Deployment (no IIS required to run RS any longer)
     – Rich-text support
     – Enhanced visualiztion (graphing)
     – New Word rendering (render reports to Microsoft Word)
  Deprecation
     – Many ‘old’ features ARE REMOVED/GONE (those that have been deprecated for some time – 60/65/70 compat modes, nolog / truncateonly syntax, etc.)
