original data set to improve query efficiency. Shortcomings are also more obvious, updating the reviewer data will be more troublesome.(4) Data coupling?: SQL does not allow the deletion of external data that has already been used, such as "Bear three" in the reviewer table has been assigned to the borrower bear big, then in the reviewer table will not be allowed to delete the bear three this data to ensure data integrity, and
I remember that I wrote MySQLvsNoSQL more than half a year ago, and I have always insisted on using a database to store KV data, because it not only guarantees data security, it is mainly found that the qps of most systems is not that high at all, and the level of 4 K is very small, which MySQL can fully meet, because the optimized KV request can be implemented on the MySQL SQL layer. I remember writing MySQL vs N

oracle with PHP4 should be improved.In LINUX, I only tested the performance of mysql because I didn't install oracle. It is said that in LINUX, oracle has good performance but cannot be tested.In addition, we put all the code used for database connection and oracle to analyze SQL statements out of the Statistical Code. Therefore, the test only takes time to exec
. In win32, only PHP3 can connect to the oracle Database. Therefore, only the performance of connecting oracle with PHP3 is tested. I believe that after the official version of PHP4 is released, the speed of connecting oracle with PHP4 should be improved. In LINUX, I only tested the performance of mysql because I didn't install oracle. It is said that in LINUX, oracle has good
Free databases to be tested include SQLite, Access, MySQL, and MongoDB: Because most applications are implemented in multiple threads, thread synchronization and code locking are required. Before talking about multithreading, let's first talk about the test results on the premise of a single thread, that is, Access data is much less efficient, and the other three are relatively fast, similar to each other. The following is a multi-threaded conclusion
, no tests were conducted. In win32, only PHP3 can connect to the oracle Database. Therefore, only the performance of connecting oracle with PHP3 is tested. I believe that after the official version of PHP4 is released, the speed of connecting oracle with PHP4 should be improved. In LINUX, I only tested the performance of mysql because I didn't install oracle. It is said that in LINUX, oracle has good

It is very important to develop a database application and select a good database. This article compares three types of databases: SQL Server, Oracle, and DB2. It provides some reference for you to select a database. Openness SQL Server It can only run on windows without any openness. The stability of the operating system is very important to the database.
