SQL Server data rows: Heap and B-tree (binary two fork tree). People who have learned the data structure know that the advantages of binary tree are: The rapid use of binary method to find data, data pages using a two-way linked list end-to-end connection. Let's introduce the heap in the data structure. The data in the heap is not in any order and the data page is not connected to the end. So how do you find the data in the heap? The structure and IAM

Generally speaking, to understand a domain, you need to start from the following aspects: patents, papers, blogs, and the homepage of research institutions.
If you study patent open classes, you will not post the papers. You can search for them directly by google or on the internal network of the school.

Although the design circle is popular not to "repeat the wheel" argument, but beginners still need to learn from the bottom to the top of the robot's entire design process, and then find themselves interested in or good at a certain direction to dig deep, become an expert (not brick house ha).2.

To understand the index access method, you must first know the index structure.

Page
Page is the basic unit for SQL Server to store data. It is 8 kb in size and can store table data, index data, execution plan data, allocation bitmap, and available space information. The page is the smallest I/O unit that SQL server can read and write. Even if a row of data is read, it loads the entire page into the cache and reads data from the cache.
