Data architecture defines the collection, storage and movement of data across an organization while information architecture interprets the individual data points into meaningful, useable information. DBMS architecture helps in design, development, implementation, and maintenance of a database; The simplest of Database Architecture are 1 tier where the Client, Server, and Database all reside on the same machine; A two-tier architecture is a database architecture where presentation layer runs on a client and .data is stored on a Server The conceptual level does not care for how the data in the database is actually stored. . ORACLE manages the storage space in the data files of a database in units called data blocks. Learn about its advantages over other database systems, as well as the different types of distributed databases. OLTP is basically focused on query processing, maintaining data integrity in multi-access environments as well as effectiveness that is measured by the total number of transactions per second. 4.
