With the help of a diagram, the chapter also explains the three-level architecture. The chapter points out that the three-level architecture provides a higher level of program/data independence. The three-level architecture proposed for the DBMS suggests that the three schemas are divided among ...

There are many possible alternatives for architecting a distributed DBMS. The simplest is the client/server architecture, where a number of client machines access a single database server. The simplest client/server systems involve a single server that is accessed by a number of clients (these can...
DBMS_OUTPUT.PUT_LINE(ExtractInvNo); end; This will output 1232 to the output window. Finding Blockers This can be done really quickly by querying the v$session_blockers table. It will quickly return which sessions are being blocked and by who. Not very difficult to find but it certainly ...
It is an extension of the 2-tier architecture. In the 2-tier architecture, we have an application layer which can be accessed programatically to perform various operations on the DBMS. The application generally understands the Database Access Language and processes end users requests to the DBMS....
Provide a way of loosely grouping objects through tagging. To enter multiple keywords, sep arate them with commas. 1.2.2 Setting Model Options You can set EAM model options by selecting Tools Model Options or right-clicking the diagram background and selecting Model Options. You can set ...
(a) What is a multivalued dependency in DBMS? (b) Give an example. What is interaction coupling? What is MVVM architecture? What are the components of event-based architecture? What is RSTP in networking? What is a mesh network?
Control the behavior of IM expressions using theDBMS_INMEMORY_ADMINpackage. For example, theIME_CAPTURE_EXPRESSIONSprocedure prompts the database to identify and gradually populate the hottest expressions in the database. TheIME_POPULATE_EXPRESSIONSprocedure forces the database to populate the expressions...
The recovery_window_goal parameter of DBMS_RA.CREATE_PROTECTION_POLICY specifies the interval (typically in days) within which point-in-time recovery must be possible, counting backward from the current time. Consider a recovery_window_goal setting of 1 day. At midnight on August 7, the goal ...
