You can quickly learn and master the HBase development process and know key interface functions in a typical application scenario.

Description

Develop an application to manage information about users who use service A in an enterprise. Table 1 provides the user information. Procedures are as follows:

Create a user information table.
Add users' educational backgrounds and titles to the table.
Query user names and addresses by user ID.
Query information by user name.
Query information about users whose age ranges from 20 to 29.
Collect the number of users and their maximum, minimum, and average age.
Deregister users and delete user data from the user information table.

Delete the user information table after service A ends.

Data Planning

Proper design of a table structure, RowKeys, and column names enable you to make full use of HBase advantages. In the sample project, a unique ID is used as a RowKey, and columns are stored in the info column family.
