Typical Scenarios of the HBase Data Read/Write Sample Program

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.
