軟體簡介:
　
This course focuses on SQL Server 2014 and two of the latest additions to
the database engine. We first look at how the shift in technology trends
established the need for a different breed of technologies. Columnar, or
Column-Oriented, databases have become increasingly popular in data warehousing
applications because they allow for better compression and multi-fold performance
improvements, and we'll see how SQL Server 2014 implements this with clustered
columnstore indexes. In addition, as technology makes a bigger shift in hardware
to multi-core CPU architectures and large amounts of memory are even cheaper
and more attainable, it's important for software to adjust and utilize these
changes. We'll see how In-Memory OLTP addresses these trends and more, letting
you create tables in memory, eliminating locks and implementing optimistic
multi-version concurrency. This course discusses in depth In-Memory OLTP (memory
optimized tables), previously known as Hekaton. We'll cover creating memory-
optimized tables, loading data, durability and the affect that has on the
transaction log. We'll also look at indexing in detail, explaining the new
index types created specifically to support In-Memory OLTP and how and when
to apply each type based on your use case and we'll discuss how In-Memory
OLTP and Clustered Columnstore indexes can fit a variety of applications while
comparing them with each other and traditional disk-based tables and indexes.
