What is the meaning of temporal data?

Temporal data is simply data that represents a state in time, such as the land-use patterns of Hong Kong in 1990, or total rainfall in Honolulu on July 1, 2009. Temporal data is collected to analyze weather patterns and other environmental variables, monitor traffic conditions, study demographic trends, and so on.

What is a temporal data warehouse?

Temporal data warehouses (TDWs) have been developed for the management of time-varying data in dimensions. Time in the temporal starnest schema is not treated as another dimension but as time attributes in every temporal dimension, i.e., dimension tables dependent on time.

What is Bitemporal data modeling?

Bitemporal Modeling is a specific case of Temporal database information modeling technique designed to handle historical data along two different timelines. This makes it possible to rewind the information to “as it actually was” in combination with “as it was recorded” at some point in time.

Is temporal data time series?

Temporal databases contain data that is time sensitive. That is, the data are stored with time indicators such as the valid time (time for which the entry remains valid) and transaction time (time the data was entered into the database).

What is temporal analysis?

What is temporal time series?

Time-series: ordered real-value measurements at regular time intervals. Temporal sequences: timestamped at regular or irregular time intervals.

What is temporal trend?

Temporal trends are assessed by comparing the year-specific intercepts against those of two sub-models: (the same level in each year), and (a linear trend). There are two groups of problems that have been encountered in the past, corresponding to the two main stages of the trend assessment.
