To understand and master a variety of data types the command mode of operation, and the operation of various types of data values. Meanwhile, skilled memory list, the hash, and the set of ordered set of common data types operation command. To complete instructions in accordance with the corresponding instruction format.

In this study, the summary and relevant experience harvesting, can be divided into the following points:
- Through the experiment, to learn how to use the commands way REDIS database management functions. A preliminary understanding of the various types of command data mode of operation, as well as various types of data values. At the same time, to complete the basic instructions in accordance with the corresponding instruction format.
- When the collection of the experiment and the ordered set is operated, part of the instructions related concepts SCORE. At the same time, basically mastered the difference between a collection and an ordered set, the key is: there is no set of weights, and there is an ordered set of weights that meaning.
- During the experiment, without first on the concept of "key" to give "value", and takes the value or manipulate the values, then you will be prompted redis non-empty or direct error. The key is to have a clear stroke order period. Part of the data type of instruction is to add the prefix plus the ADD, and some part is the prefix plus the set, which is the same reason for removing elements. Thus, requirements for successful operation of the instruction is the degree of memorizing the instruction type.
