Data marts are combined into a data warehouse cannot be built alone without considering data marts. Both has equal importance to built proper data warehouse.
One of the biggest benefits is that you can archive your data to a data warehouse. This can keep your main "production" database smaller which can provide some performance benefits. Also you can use the data warehouse to run complex queries and data-mining without adverse effects on the performance of your "production" application.
What are the three most common forms of data warehouses? is a smaller form of a data warehouse that is often used by a single department or function. An independent data mart is a tiny warehouse that is built for a strategic business unit (SBU) or a department, but it does not have a central data source (EDW).

A data warehouse has multiple functional areas whereby a centralized organizational unit is responsible for implementing it. On the contrary, data marts focus on particular functional areas hence are simple forms of a data warehouse.
what is iteration?
Hi, 1. Subject Oriented 2. Integrated 3. Nonvolatile 4. Time Variant
Nonvolatile, it stores its data with or without power.
it's data warehouse....data warehouse: it is a collection of multiple databases or it it is repository of data.data mining it is the process of extracting data from data warehouse.
Non-volatile. It retains its memory even if power is removed.
Volatile memory loses its stored data when power is lost, while nonvolatile memory retains its stored data even without power. Examples of volatile memory include RAM, while nonvolatile memory includes hard drives and SSDs.
Data warehouse is a house where current as well as historical data can be stored.
Data warehouse is the database on which we apply data mining.

Metadata is data about data that provides information such as the structure, format, and characteristics of the data stored in a data warehouse. It is used in data warehouse architecture to facilitate data integration, data governance, and data lineage. Metadata helps users understand and manage the data in the data warehouse efficiently.
Every data structure in the data warehouse contains the time element. Why?

A data warehouse architecture is similar to various relational database systems. What makes the best architecture is the organization of the warehouse itself and the data it consist of.
