9. Big Bet Availability Features Huge number of new availability features Database Mirroring Database Snapshots Online database restore File & Page Dedicated Admin Connection Online Index Build and Reorganize Snapshot Isolation

10. Data Partitioning Partitioning breaks a single object into multiple manageable pieces Transparent to the application Allows easy management of very large tables and indexes The row is the unit of partitioning All partitions run on a single SQL Server database Partitions can be created or dropped with virtually no loss of availability to the table Table fully available while loading, indexing a new partition Create new and drop old partition quickly Fastest possible load rates If all indexes are “aligned”, moving partitions in or out of a table is possible “Sliding window” scenarios

11. Native SQL type Use for column, variable or parameter Can represent XML 1.0 documents XML 1.0 fragments (0 to n element nodes and text nodes at top) Can be constrained by XML Schema collection Methods on XML data type query(), value(), exist(), modify(), nodes() Storage of XML instances As LOB (2 GB) in efficient binary representation XML encoding transformed to UTF-16 Well-formed and validation checks XML Datatype

12. XML Schema Support XML Schema (World Wide Web Consortium [W3C] standard) Rich mechanism for type definitions and validation constraints Can be used to constrain XML documents Benefits of typed data Guarantees shape of data Allows storage and query optimizations XML type system Store XML schemas in system metadata Does not preserve annotations

13. XQuery: query XML documents and data Standards-based: W3C working draft In document 123, return section heading of section 3 and later SELECT id, xDoc.query(' for $s in /doc[@id = 123]//sec[@num >= 3] return {data($s/heading)} return {data($s/heading)} ') FROM docs XML Query

14. XML Index Create primary XML index on XML column CREATE PRIMARY XML INDEX idx_1 ON docs (xDoc) Creates secondary XML indexes on values (VALUE), paths (PATH), properties (PROPERTY) CREATE XML INDEX idx_1_Tag ON docs (xDoc) USING XML INDEX idx_1 FOR PATH Speeds up queries Results can be served directly from index Entire query is optimized Same award winning cost based optimizer Indexes are used as available

15. Insert, update, & delete XQuery extensions XML sub-tree modification: Add or delete XML sub-trees Update values Add a new section after section 1: UPDATE docs SET xDoc.modify('insert Background after (/doc/section[@num=1])[1]') XML Data Modification

16. Client XML Data Access Native Access SQLOLEDB As DBTYPE_WSTR Large string As ISequentialStream SAX or DOM can be built from server character stream Down Level, ADO and ODBC: large string Managed Access & CLR (XML datatype) XML Type exposed as SqlXml (System.Data.SqlTypes) XmlReader can be obtained using sqlxml.CreateReader()
