This article is a high-level guide to the structure of the storage engine, recommending configuration parameters, the best hardware for SQL Server, and innovative ways to store large amounts of data through files and filegroups. This article also outlines the new dynamic features of the SQL Server 7.0 storage engine.
Informix Dynamic Server segmented storage, also known as fragmented storage, is based on the principle of regularly dispersed records or indexes in a datasheet to different areas of the disk, to store data on multiple disks, and to increase the efficiency of the database by reducing the competition for disk I/O. In contrast to this is the basic
, it is found that the price of such servers is not low (for some companies, such a price does not matter, it is impossible to use such a small NAS storage service, but for small companies, the cost is still very important ), A good friend has a PC host that is idle and not used. The machine is normal, but the design and processing capabilities cannot be kept up, so he decided to use it, find another NAS server

Brief introduction
The column storage index already exists in SQL Server 2012, but only nonclustered column indexes are allowed in SQL Server 2012, which means that the column index refers to the underlying data on the original row storage index, and therefore consumes more storag
