updating data and deleting data. If you change the column in the WHERE clause in the update and delete to B, the speed is the same as no index because the index is invalid. Therefore, the index can greatly increase the query speed, for delete and update operations, if the column in the WHERE clause uses an index, even if the index needs to be re-build, it is likely that the speed is faster than not using the index. The index is obviously a burden on the insert operation. At the same time, the i

The virtual platform and the traditional network environment coexist, the application server and the database server to carry on the database audit in the hybrid cloud platform, must differentiate from the traditional deployment way, this paper takes the vsphere virtual platform as an example, carries on the discussion to the

Why do you create an index? This is because creating an index can greatly improve the performance of the system. First, by creating a unique index, you can guarantee the uniqueness of each row of data in a database table. Second, it can greatly speed up the retrieval of data, which is the main reason for creating indexes. Thirdly, the connection between tables and tables can be accelerated, particularly in terms of achieving referential integrity of t

2011 will be remembered, because this year the SQL will die; this year, the relational database retreated from the first line; this year, developers discovered that they didn't have to convert each object into a table structure to persist data. 2011 is a document database year, despite the steady development momentum, through the past eight years of development, there are now a variety of stable document d

1, LINQ to SQL benefits Before LINQ to SQL is launched, we just form a string of SQL statements, and then, Pass ado.net to SQL Server, returning the result set. The flaw here is that if you have a problem with the SQL statement, you only know it at runtime. And not everyone knows the database. LINQ to SQL is available in all projects that revolve around data. Especially when you are missing an expert on SQL Server in your project, the powerful featur
