To be honest, I don't want to use SQL Server at all. Some places seem to be the advantage in others. In my opinion, it is rubbish, such as its double-layer verification. If it is not a mixed landing method, it will report "SQL Server, which does not have the SQL Server, which is not trusted. SQL Server requires users who log in to the database server first of all, the database user, adding database users, I am also annoying.
In contrast, I prefer Mysql and Oracle, I think these two database servers are very good, but Oracle is big, MySQL has no interactive interface, but I am still
I like to use it. Oracle is used for work reasons, usually do something to do, don't use it. Microsoft's SQL Server interactive GUI user interface is good, many use
Users who are used to Microsoft prefer to use, but I don't like it, although I still use Microsoft's operating system, but I have fewer use of Microsoft. Oh, it is pure personal hobbies, and has nothing to do with other.
SQL Server can only run on Windows, no slightest openness, the system's system's stability is important to the database, while Microsoft's Windows is too stable, too much vulnerability. SQL Server Biased Desktop Applications, NT Server is only suitable for small and medium-sized businesses. And the reliability, security and scalability of the Windows platform are very limited. It is not like UNIX, especially when handling big data, Oracle runs on all mainstream platforms (including Windows). Fully support all industrial standards. Using a fully open policy. You can make customers choose the most suitable solution. Find support for developers.
In scalability, parallelism, SQL Server parallel implementation and coexistence models are not mature. It is difficult to handle increasing number of users and data volumes. Smalllability is limited. The Oracle Parallel Server provides high availability and high-profit clusters of the WINDOWNT by sharing a set of nodes to share WINDOWNT capabilities. If WindowsNT does not meet the needs, the user can move the database into UNIX.
Security aspect
SQL Server did not get any safety certificates. Oracle Server gets ISO standard certification for the highest certification level.
In performance
SQL Server has a poor user performance
Oracle
The highest performance, keeps TPC-D and TPC-C under Windows.
Risk
SQL Server
The code completely rewritten has experienced long-term testing, continuous delays, and many functions take time to prove. It is not very compatible with early products. Use needs to take a risk.
Oracle
Long-term development experience is fully compatible. Get a wide range of applications. There is no risk at all.
