Refers to the time a program or device takes to locate a particular piece of data. The time it takes for a disk drive to move its head(s) from one track to another. The seek time depends on the power of the servo motor that moves the head, the mass of the heads, the number of tracks traversed and the time taken to position the heads over the target track accurately enough to start data transfer (which includes several variables). The terms seek time and access time are often used interchangeably. Technically speaking, however, the access time is often longer than the seek time because it includes a brief latency period.
Metadata is data that is about data.?æ Although it describes the data, it's not considered business data. Master data is business data. Run-time data is data that is in the process of being run.
Every data structure in the data warehouse contains the time element. Why?
Time dependent data
Repetitively measured data is referred to as time series data. Time series data is collected at multiple points in time and can show patterns or trends over a specific period. It is commonly used in forecasting and trend analysis.
Data for which an independent variable is time.
Data life cycle refers to the time from creation and the initial storage of data to the time that the data becomes obsolete and it is deleted. Data life cycle management is the approach to managing data using automated processes to organize data in a system.
data collected over several time periods is what type of data?

Secondary data is faster, cheaper, and less time consuming while primary data will be time consuming and the cost to conduct it is higher.
The time required by a processor to access data or to write data from and to memory chip is referred as access time.

Parallel data transfer is transferring multiple bits of data at a time.
