Data Item Set

A data item set is a machine-processable artifact that contains one or more data items.

AKA: Data Object, Data Set, Dataset.
Context:
- It can range from being a Structured Data Object (with a Data Structure) to being an Unstructured Data Object.
- It can range from being an Unordered Data Object to being an Ordered Data Object.
- It can range from being a Categorical Dataset to being a Mixed Dataset to being a Continuous Dataset.
- It can range from being a Public Dataset to being a Private Dataset.
- It can range from being a Persistent Data Object to being a Temporary Data Object.
- It can range from being a Sparse Data Object to being a Standard Data Object to being a Dense Data Object.
- It can range from being a Human-Processable Dataset to being a Human-Nonprocessable Dataset (such as a Binary File).
- It can range from being a Real-World Dataset, to being a Realistic Dataset, to being a Synthetic Dataset.
- It can be associated to one or more Dataset Itemset (subset of data items), such as a frequent itemset.
- It can be, depending on the Data Item Type, a Non-Vector Dataset, a Vector Dataset, a Graph Dataset.
- It can have outlier records.
Example(s):
- a Data Record Set.
- a Data Item String.
- a Data Item Sequence.
Counter-Example(s):
- a Set Member, a non in a Computer Program.
- a Data Structure, a set of Data Constraints.

- A data set (or dataset) is a collection of data, usually presented in tabular form. Each column represents a particular variable. Each row corresponds to a given member of the data set in question. Its values for each of the variables, such as height and weight of an object or values of random numbers. Each value is known as a datum. The data set may comprise data for one or more members, corresponding to the number of rows.

- In computer science, data is anything in a form suitable for use with a computer. Data is often distinguished from programs. A program is a set of instructions that detail a task for the computer to perform. In this sense, data is thus everything that is not program code.
- In an alternate usage, binary files (which are not human-readable) are sometimes called "data" as distinguished from human-readable "text". The total amount of digital data in 2007 was estimated to be 281 billion gigabytes.
