Topic: data as a named set of data objects
Topic: data compression algorithms
Topic: object modification
Subtopic: data derived from information up

Quote: data derives from knowledge and information, not vice-versa; there are no isolated pieces of simple facts [tuomI3_1999]
Quote: data is procedural and positional forms of information that can be modeled, represented, and processed [tuomI3_1999]
Quote: knowledge and information are essentially social; technology has a supporting role; e.g., a thermometer measures temperature [tuomI3_1999]

Subtopic: data as type and value up

Quote: a FAD object is a pair of items called the object's type and its value [martJJ_1980]

Subtopic: L-value vs. R-value up

Quote: the location of an item of data is known only if some name gives access to its L-value; the value itself is its R-value [frasAG6_1971]

Subtopic: information vs. data up

Quote: data requires further processing to be meaningful, while knowledge implies an individual knower [blaiAM_2010]
Quote: distinguish information and data; e.g., an employee's salary is data that doesn't need a separate entry; access by a field [cbb_1980 OK]

Subtopic: input vs. data up

Quote: input is information that controls a program; input is different than data; e.g., the number of data points and the number of iterations vs. the data itself [moorCH6_1970]

Subtopic: data is a number up

Quote: a data object is a number since it is part of the initial state of a computation [cbb_1990 OK]

Subtopic: data description up

Quote: PADS is a declarative data description language for describing the physical layout and semantics of ad hoc data; generates tools for parsing, statistical profiling, conversion, and XQueries; as good or faster than Perl [fishK6_2005]

Subtopic: skewed distribution up

Quote: hash inputs usually have one of these characteristics: common substrings arranged in different orders, only a few bits differ, lengths differ, or nearly all zeros [esteC6_2014]
