Well, today and everyone in sync to explain the knowledge of MySQL. is the most basic knowledge.

First, the basic concept of the database

1. Server: The computer installed the server class software is the server, that is, each notebook can be used as a server. For example: Installing Apache servers in notebooks

2. Database server: Installed the database server side of the software, is the database server, that is to say: Notebook can also install database server, notebook as a server,

Summary: The software that installs the server class in a notebook can act as a function of that server.

Tip: Since the Apache server is installed, there is a display panel (monitor) you can see, but MySQL can't see also touch, this is a lot of beginners to the database is very afraid of one of the reasons, always feel insecure, said more ha.

3.B/S and C/s mode---which is already from the examination of the surface of the question, often mentioned in the blog

Tip: Remember these points mainly, the words must be written. All right. I'll write it myself.

b/S: is a browser/server, do not need to install the appropriate software, user software does not need to update, data processing is done on the server, more secure, such as Web version and web version of QQ.

C/S: is a client/server, need to install the appropriate software, user software needs to be updated, data processing in the client, security is relatively weak, such as: the client's QQ

In fact: Everyone in life is in use, but not to understand it, every day with the love of the web version of the odd Art watch TV is b/s mode. But you want to download the love of the odd art client, that is the C/s mode. Just remember one of the features, and the other is just as good as remembering the other.
