[edit] Topic of this article
I'm starting this article now that type system is moved out of the way. Type is an abstract concept of type systems but data type is a concrete type of data. While Type system gives an overview on issues on designing a system, this article can give an overview on different kinds of data types used in practise. The topic relates to data structure (an article in need of cleanup) and some stuff in there about the building blocks could be dealt with here. The way I see it, a node of a data structure or data without smaller operable structure is a data type. --TuukkaH 10:46, 28 February 2006 (UTC)
[edit] Lost info?
The C++ entry has links to datatype (no space) and sub-entries on strong/weak, safe/unsafe, nominative/structural, and static/dynamic typing. These links lead now to the article data type but these entries are missing.
Is this by design or mistake?

- The article that was here with those sections is now located at Type system. If you'd like to be really helpful, you can click "What links here" and fix the broken links! —donhalcon〒 14:39, 28 February 2006 (UTC)
- Similarly some articles are looking for Static_and_dynamic_typing. Mathiastck 16:55, 23 August 2006 (UTC)

The compound word "datatype" is sometimes used in place of "data type". It is not clear whether this is an "official" new word or simply the product of us making up new words as we go along. But, it works. 198.102.62.250 01:21, 11 November 2006 (UTC)
[edit] defined range.
I know I am almost on a lost crusade here but I still believe it to be important to mentions concept of choosing a range needed and let the actual hardware representation to the compiler. And I would like to go further on this as this concept gives are real win/win situation:
- It is easier to understand for programmer
- 100% portable
type Range_Type is range -5 .. 10;means the same on any CPU or language implementation. - Better optimization: The compiler is free to choose either Byte or Integer for the above definition - depending on optimisation setting (speed vs. size).
The concept is so elegant and powerful that it is a shame that is almost forgotten (AFAIK Pascal introduced the notion in the 1970th). So I believe it is important to mention so "Byte, Word, Integer, etc. pp" are not "god given" (Independent of which god you believe in) but what they really are: An implementation detail for which they are alternatives.
See wikibooks:Ada_Programming/Types/range or wikibooks:Ada_Programming/Types/digits for a syntax example.

[edit] Data Structures & Abstract Types
Right now, these are both empty sections with 'main article' links in them. Usually you see those prior to at least a short summary of the subject in question, so can someone write that up? Or simply move them to the 'see also' section? --124.177.141.85 15:32, 26 March 2007 (UTC)
[edit] merge from Dynamic data typing
The article at Dynamic data typing is very short and it seems to me it would be better as a section in this article.--NHSavage 21:19, 27 March 2007 (UTC)
- Actually on second thoughts it would be better to merge with Type system. I'll change the template.--NHSavage 09:11, 31 March 2007 (UTC)
