Data Warehousing Directory » Concepts

Data warehousing is the recording and storing of healthcare information. A storage device can hold information, process information or both. Devices that process data (data storage equipment) can either access a separate portable recording medium or a permanent component to store and retrieve information.

Electronic data storage requires electrical power to store and retrieve data. Electromagnetic data may be stored in either an analog or digital format on a variety of media. This type of data is considered to be electronically encoded data, and most electronically processed data storage media are considered permanent storage, or data that will remain stored when power is removed from the device.
