Data classification can be viewed as a multitude of labels that are used to define the type of data, especially on confidentiality and integrity issues. [1] Data classification is typically a manual process; however, there are tools that can help gather information about the data. [2] Data sensitivity levels are often proposed to be considered. [2]
The quantity is called the relative redundancy and gives the maximum possible data compression ratio, when expressed as the percentage by which a file size can be decreased. (When expressed as a ratio of original file size to compressed file size, the quantity R : r {\displaystyle R:r} gives the maximum compression ratio that can be achieved.)
Data redundancy leads to data anomalies and corruption and generally should be avoided by design; [5] applying database normalization prevents redundancy and makes the best possible usage of storage. [ 6 ]
Database design is the organization of data according to a database model. The designer determines what data must be stored and how the data elements interrelate. With this information, they can begin to fit the data to the database model. [1] A database management system manages the data accordingly.
eBay v. Bidder's Edge, 100 F. Supp. 2d 1058 (N.D. Cal. 2000), was a leading case applying the trespass to chattels doctrine to online activities. [1] [2] In 2000, eBay, an online auction company, successfully used the 'trespass to chattels' theory to obtain a preliminary injunction preventing Bidder's Edge, an auction data aggregator, from using a 'crawler' to gather data from eBay's website.
Grey relational analysis does not attempt to find the best solution, but does provide techniques for determining a good solution, an appropriate solution for real-world problems. The theory inspired many noted scholars and business leaders like Jeffrey Yi-Lin Forrest , Liu Sifeng , Ren Zhengfei and Joseph L. Badaracco , a professor at Harvard ...
In computer science and information theory, set redundancy compression are methods of data compression that exploits redundancy between individual data groups of a set, usually a set of similar images. It is wide used on medical and satellital images.
A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. [1] [2] Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents. On retrieval, the calculation is ...
