Transaction processing is a key issue for all large database products. database vendors have spent a lot of energy in this aspect, different transaction processing methods may cause huge differences in database performance and functions. Transaction processing is also a problem that must be deeply understood by database administrators and database application developers. Negligence on this issue may lead to application logic errors and inefficiency. Next we will discuss some of their differences

Document directory Difference between Schema and user Supplement Schema in SQL Server We know the database, as its name implies. the most important thing is data management, and data is stored in tables in the system. Therefore, almost all the mechanisms and operations in the database are centered around the table. the importance of tables can be imagined. how are tables stored in the database and ac

　　LieHuo. Net database integrationOracle and Microsoft are both major database manufacturers, and there are also a lot of enterprises adopting the two products. This article compares Oracle and SQLServer images. Database images are used to move database transactions from one database to another in different environments. An image copy is a backup copy and cannot be accessed directly. It is used only when an error is restored.

in the world, almost 85% of them use DB2 database servers, and about 5% in China to 97 years. Scalability and concurrency: SQL ServerThe parallel implementation and coexistence model are not mature. It is difficult to process the increasing number of users and data volumes.
