Database Management Systems

Here, the transaction wants edit the data item.

A node that must references data on other nodes to complete its part in the distributed transaction.

Student names consist of text characters and must be stored in string arrays to preserve the text format. Prices represent numerical values and are stored in numeric arrays for arithmetic operations. This distinction is fundamental in programming - strings for text, numbers for calculations.

Data consists of raw, unorganized facts, figures, or symbols that have not been processed or given context. Information is what results when data is processed, organized, or structured to provide meaning and usefulness.

A PL/SQL record is a group of related data items. For example, the data about a student like roll no., name, date of birth are logically related to each other but have different types. A record containing a field for each item lets the user treat the data as a logical unit. Thus, making it easier to organise and represent. The syntax for creating a record is

type type_name is record (fielddeclaration1,fielddeclaration2...); 

A package is a collection of related PL/SQL objects like procedures, functions and triggers created as a single unit. It is used to store related objects in a single file. A package has two parts - Package specification and package body. The specification part contains the declaration of procedure, functions and triggers whereas the body part contains the actual implementation or code of all the subprogram declared in specification part.

This is the data base which is used for adding the product_profile table.

Data set invokes the method Update for changing any specific data base in ASP.Net.

It gives user's access privileges to database. Hence, it is DCL command and not a TCL command. 

The contents of redo log buffer are transferred periodically from memory to the online redo log files on disk by the log writer background process.

A tablespace is composed of one more datafiles on disk.

This cache is managed using the least recently used algorithm.

This option starts up the database using the static non default attribute file to start up database.

When any changes are made to the database such as updates to data or creating or dropping database objects, the changes are recorded to the redo log files first.

The contents of the database buffer cache are written to datafiles on disk by the database writer background process.
