In case the number is even like 8, then the median is the average of 4th and 5th data point. Characteristics of Database Tables: A relational database consists of a collection of tables. Data can be defined as the figures or facts which can be stored in or can be used by a computer. It is known for its routable network properties where each node act as a “router” to forward the traffic to other specified nodes in the network. Big Data is a term that is used for denoting the collection of datasets that are large and complex, making it very difficult to process using legacy data processing applications. The heading part consists of the table name and the column names. Security – The data which is left at the fixed location is more secure as compared to mobile data. For example, photos, video clips, ... Another important characteristic of big data is the value of the information extracted from the data. 1. Provide examples. Portability -The Ability to move a device within a learning environment or to different environments with ease. 1. Use the colors seen on the chromatograms to determine which M&Ms candies you tested contain Yellow 5. Below are major characteristics of data warehouse: Subject-oriented – A data warehouse is always a subject oriented as it delivers information about a theme instead of organization’s current operations.
