What are the various Oracle database objects?

by

Tables: This is a set of elements organized in vertical and horizontal fashion.

Tablespaces: This is a logical storage unit in Oracle.

Views: It is virtual table derived from one or more tables.

Indexes: This is a performance tuning method to process the records.

Synonyms: This is a name for tables.

Oracle Database consists of various objects that allow users to store, organize, and manage data. Here are some of the key Oracle database objects:

  1. Tables: The fundamental storage unit where data is stored in rows and columns.
  2. Views: Virtual tables that are based on the result of a SELECT query. Views do not store data themselves but provide a way to present data from one or more tables.
  3. Indexes: Structures that provide a faster way to retrieve data from tables. Indexes are created on one or more columns of a table.
  4. Synonyms: Alias or alternate names for database objects like tables, views, or procedures.
  5. Sequences: Objects used to generate unique numbers in a sequential order, often used for primary key values.
  6. Procedures: A set of SQL or PL/SQL statements grouped together as a named unit, which can be stored and executed in the database.
  7. Functions: Similar to procedures but return a value. Functions can be used in SQL statements wherever an expression can be used.
  8. Triggers: Special types of stored procedures that are automatically invoked (or fired) in response to specific events, such as an insert, update, or delete operation on a table.
  9. Packages: A collection of related procedures, functions, and other database objects grouped together as a single unit.
  10. Materialized Views: Similar to views but store the result set physically in the database, providing faster access to the data.
  11. Clusters: A group of tables that share the same data blocks and are often used for storing related data together to improve query performance.
  12. Database Links: Connections between two databases, allowing data to be accessed and modified in another database.

These are just some of the key Oracle database objects. Each serves a specific purpose in organizing and managing data within the Oracle Database system.
