Types of Tables

  • Base Tables: These are the standard tables that store data directly in the database. They can be created, modified, or deleted as needed. Base tables hold persistent data and are fundamental for data storage.
  • View Tables: Views are virtual tables created by querying one or more base tables. They do not store data themselves but present data dynamically based on the underlying tables. Views can simplify complex queries and enhance security by restricting access to specific columns or rows.
  • Global Temporary Tables: These tables store session-specific data temporarily. Data in a global temporary table is only visible to the session that inserted it and is typically used for intermediate calculations or staging data.
  • Partitioned Tables: These tables are divided into smaller, more manageable segments (partitions) based on a specified key. Partitioning can improve performance by allowing parallel processing and easier data management.
