SQL Server Architecture – Are you ready ?

Explaining SQL Server Architecture in one diagram or Image is very difficult.

Even if we get the same from any blog or website, it is not so easy to understand.
Many of us till date did not even know, what are different engines and their use.

Table & Index Architecture

In this article, we take a brief look at the different kinds of indexes that exist in SQL Server, and how they work. To get us started on this journey, we first need to answer these two questions:

• What is a table?
• What is an index?

SQL SERVER – 64 bit Architecture and White Paper

In supportability, manageability, scalability, performance, interoperability, and business intelligence, SQL Server 2005 provides far richer 64-bit support than its predecessor. This paper describes these enhancements. Read the original paper here. Following abstract is taken from the same paper. Another interesting article on 64-bit Computing with SQL Server 2005 is here.

The primary differences between the 64-bit and 32-bit versions of SQL Server 2005 are derived from the benefits of the underlying 64-bit architecture. Some of these are:

• The 64-bit architecture offers a larger directly-addressable memory space. SQL Server 2005 (64-bit) is not bound by the memory limits of 32-bit systems. Therefore, more memory is available for performing complex queries and supporting essential database operations.
• The 64-bit processor provides enhanced parallelism, thereby providing more linear scalability and support for up to 64 processors, and yielding stronger returns per processor as compared to 32-bit systems.
• The improved bus architecture enhances performance by moving more data between cache and processors in shorter periods.
• A larger on-die cache allows for faster completion of user requests and more efficient use of processor time.
