Based on typical scenarios, users can quickly learn and master the HBase development process and know important interface functions.

Scenario

Develop an application to manage information about users who use service A in an enterprise. Table 1 provides the user information. The operation process of service A is described as follows:

Create a user information table.
Add diplomas and titles to the user information table.
Query user names and addresses by user ID.
Query information by user name.
Query information about users whose ages range from 20 to 29.
Collect statistics on the number and the maximum, minimum, and average ages of users.
Deregister users, and delete user data.

Delete the user information table after service A ends.

Data Planning

Proper design of the table structure, RowKeys, and column names can give full play to the advantages of HBase. In this example, the unique ID is used as the RowKey, and columns are stored in the info column family.

CAUTION:

HBase tables are stored in Namespace:Table name format. If no namespace is specified when a table is created, the table is stored in default. The hbase namespace is the system table namespace. Do not create service tables or read or write data in the system table namespace.
