Deploying database management systems? Find information resources on creating a DBMS architecture and database strategy, and get tips on database design and development and managing a database implementation.
A Database Management system can be centralised(all the data stored at one location), decentralised(multiple copies of database at different locations) or hierarchical, depending upon its architecture.1-tier DBMS architecture also exist, this is when the database is directly available to the user...
The design of a DBMS depends on its architecture. It can be centralized or decentralized or hierarchical. The architecture of a DBMS can be seen as either single tier or multi-tier. An n-tier architecture divides the whole system into related but independent n modules, which can be ...
