SQL 2014 Developer, Part 9 of 13: Advanced Data Types

In this course, you’ll learn about a system CLR type, HierarchyID, for storing hierarchical data. You’ll also take a look at using filestreams, a way to store large binary objects outside of SQL Server and let SQL Server manage the storage. You’ll also learn about sparse columns, which store null data more efficiently than before, and sequence objects that generate sequences of integers. You’ll never think of data types the same way! Then you’ll learn about the spatial models used in SQL Server to model both flat, or planar, areas as well as the surface of the earth. You’ll see how the appearances of areas on the earth are distorted when projecting them onto a flat surface, such as Google or Bing Maps on a computer screen. SQL Server uses two data types, Geography and Geometry, to support spatial data, and you’ll see their support for various shapes and how to use them in T-SQL code. You’ll also learn how to work with spatial data in SQL Server, such as to manipulate shapes as well as learn how to investigate the relationships between shapes.
