Use mongodb-Day 1

Download:

On the official website: http://www.mongodb.org/downloads system download, my system is win7 32-bit, naturally downloaded the http://downloads.mongodb.org/win32/mongodb-win32-i386-2.2.0.zip

Configuration:

1. create d: \ mongodb on disk D: and create a folder named d: \ Mongodb \ data under D: mongodb.

2. Copy the extracted exe file to the D: \ mongodb \ directory.

Usage:

1. Open cmd and go to D: \ mongodb \ To start mongod.exe.

2. Execute mongod.exe -- dbpath "D: \ mongodb \ data", as follows: (-- path followed by dbpath. If there is a space, you must use double "" to reference it)

If a warning occurs, you can ignore it. The problem does not occur during my first use.

Test:

1. Open the new cmd, go to the d: \ mongodb \ directory, and execute cmd.exe.

2. Test basic functions such as insert, update, find, and remove.

3. I learned about the content of mongodb non-relational data storage. When two different records are inserted, the storage structure may be different. During update, only the modified content is updated, but the unmodified part is lost.

Conclusion: for the first time, I used a non-relational database mongodb to record and learn it myself.
