Introduction to Oracle Database
What is Oracle Database???
An Oracle database is a collection of data treated as a unit. The purpose of a database is to store and retrieve related information. A database server is the key to solving the problems of information management. In general, a server reliably manages a large amount of data in a multiuser environment so that many users can concurrently access the same data. All this is accomplished while delivering high performance. A database server also prevents unauthorized access and provides efficient solutions for failure recovery.
Data:
- It is stored Representation of OBJECTS and EVENTS that have meaning and importance in user's environment.
- Data can Be structured or unstructed.
Structured vs. Unstructured:
- Structured data refers to information which is readily searchable by simple, straightforward search engine algorithms or other search operations;
- Unstructured data is essentially the opposite. The lack of structure makes compilation a time and energy-consuming task.
