ETL processes

ETL stands for Extract, Transform, and Load. ETL processes are used to extract data from one system, transform it into a different format, and load it into another system.

Data warehousing

Data warehousing is the process of collecting, storing, and organizing data from a variety of sources. Data warehouses are used to store large amounts of data for analysis and reporting.

Database security principles

Database security is the practice of protecting databases from unauthorized access, modification, or destruction.
