A typical day of DBA and new features of SQL Server 2008 can help - save a minute.
Bad performance is often systemic of poor queries which are systemic of bad schema design which is systemic of non-relational thinking which is systemic of project time constraints and lack of understanding of Database Design. In this talk/tutorial I'll work my way through Normalisation, we'll look at the Relation Model and how to think in sets - it's very important; throughout I'll be referring to Codd and Date's teachings. Theory aside I'll do all my demonstrations in SQL Server - concurrency, indexing, good T-SQL practices and advice.

So you heard about the new spatial functionality in SQL Server 2008, rushed back to your database and added geography and geometry columns to all your tables, eager to create the next Google Earth-beating application. You then click the Execute button and wait. And wait. And wait some more. (You get the idea). Spatial data is a rather unique beast, and designing efficient spatial queries requires specific techniques when compared to other, more traditional types of data. In this session, we look at how the SQL Server database engine satisfies spatial queries, the theory behind spatial indexes, demonstrate the effects of altering the bounding box, use the spatial system DMVs and stored procedures to your spatial database
Allowing the query optimiser do its job of simplification is an important feature if any database design. In this session, Rob takes us through ways that a database design can leverage features of the query optimiser such as redundant joins and end up with a system the provides a much simpler querying environment.
SQL 2008 Development Features
In this session we will cover 3 new enhancements to the Database Engine. Application and Multi-Server Management introduces new capabilities for managing, monitoring and exploiting your SQL Server Infrastructure through the new SQL Server Control Point and enhancements to SSMS and Policy Based Management and Data-tier application packages. SQL Connection Plans allow you to logically refer to an application in connection strings rather than servers making migration of database applications across your SQL Server infrastructure much easier. Unicode compression in R2 enhances the native data compression capabilities introduced in SQL 2008 for Unicode data using SCSU (Simple Compression Scheme for Unicode Data)
Come to this session to see how you can create a logging, monitoring and profiling solution for your existing or new SSIS packages overcoming all usual problems that a typical solution brings: increasing package complexity, longer development times and so on. The session will propose a standard, out-of-the-box solution for all of these challenges.
Among many of its functions, MDX language has one special set function - Axis() function. That function allows creation of calculated measures that are context aware and, if wanted, don't need to refer to any dimension or hierarchy in the cube. In other words, such measures are universal or independant, which means they can be used in any MDX query. In this session we will present such measures and explain how they work. We'll also show the way how to design them for various scenarios and discuss their potentials and weaknesses. Previous experience in writing MDX queries is recommended.
