If there are associated sequences in the table to be synchronized, you can manually synchronize sequence values by referring to Synchronizing Sequence Values for a Synchronization Task with GaussDB Distributed Serving as the Source Database after the task is complete. The database name, schema name...

This architecture is known as a distributed database. (For example, see Figure 1.4.) It is different from the WAN-using centralized database in Figure 1.2 in that there is a DBMS and part of the database at each site as opposed to having one computer doing all of the processing and ...
It is easier to manage a centralized database than several distributed databases. The database character set should be Unicode. You can use Unicode to store and manipulate data in several languages. Unicode is a universal character set that defines characters in almost all languages in the world...

A crawler collects information and documents through application data, DBMS(DataBase Management System) data, file documents, and web documents according to the received request list. An indexer stores the collected information/documents to a database, and generates an index database according to ...
In the lock conflict model the L locks required by each transaction are uniformly distributed over the N locks in the database. The computer system is modelled as a queueing network. Two scheduling policies for transaction activation are considered: FCFS with and without skip. In each case the...
