A disseminated record is database that is con exotically shared and inner associated with arrange hubs. It permits exchanges data and to have open record data...
Blockchain is a technology used for storing data without a central database. Data is organized in an ever-growing list of blocks with each block referencing the previous one. Like a linked list. Once a block is added to this list, it can’t be modified. The integrity is guaranteed by i...
As an expert in relational databases who also dabbles in technologies related to NoSQL and big data, Han has published two books: SQL Optimization Best Practice and Efficient Database Optimization. Emerging technologies such as cloud computing, 5G, IoT, AI, and blockchain give rise to more ...
If gs_loader is used to create system catalogs (such aspublic.pgxc_copy_error_logandpublic.gs_copy_summary) in the destination database, theall privilegepermission is required for accessing the system catalogs.For details, seegs_loader.
Because blockchain technology has the characteristics of openness, immutability, traceability and fault toler- ance, it can ensure the privacy of data transmission in the IoT scene, thus providing a secure communication environment. In this paper, the performance indexes related to the scheme are ...
Blockchain: Blockchain is a kind of distributed database or ledger that is both replicated and synchronized on the various computers that make up a network. A blockchain ensures one of distributed computing’s main goals—redundancy—because each computer in the chain holds a copy of the origin...
In the health sector, blockchain is being explored by various stakeholders to optimize processes, reduce costs, improve patient outcomes, enhance compliance, and enable better use of healthcare-related data (Mackey et al., 2019). Research on blockchain technology and its use in the healthcare ...
Before a task enters the incremental synchronization phase, ensure that long-running transactions are not started in the source database. Starting the long transaction will block the creation of the logical replication slot and cause the task to fail. If a logical replication slot fails to be cre...
Three-Tier Architecture: It adds a middle layer (application servers) between clients and database servers, reducing communication bottlenecks and improving performance. N-Tier Architecture: Involves multiple client-server systems working together, often used in modern enterprise applications. ...
