sure that you understand the basics of procedural and object-oriented programming − control structures, data structures and variables, classes, objects, etc. To understand JAVA in detail you can go through It maps the ResultSet from JDBC API to your POJO Objects, so you don’t have to care about table structures. Hibernate maps your Java POJO objects to the Database tables. It is quite easy to use stored

0-beta Broadcast Table It refers to tables that exist in all sharding database sources. Their structures and data are the same in each database. It can be applied to the small data volume scenario that operations, including the SET database manage‐ ment order used to set the database and transaction control statement as TCL. In this case, all physical databases matched with the name are traversed according is to automat‐ ically balance between the resource control and the execution efficiency. Connection Mode From the perspective of resource control, the connection number of the business side’s visit

Almost all the mature relational databases underlying database node, middleware or business system node, to further provide the basis for the control and scheduling of the cluster. In this regard, we use the cluster topology state diagram to manage to achieve configuration synchronization, notification of state changes and distributed locks to control exclusive operations. At the same time, since the governance function itself can use appropriate
