Database
A database is an organized collection of data. A relational database, more restrictively, is a collection of schemas, tables, queries, reports, views, and other elements. Database designers typically organize the data to model aspects of reality in a way that supports processes requiring information, such as (for example) modelling the availability of rooms in hotels in a way that supports finding a hotel with vacancies.
Programming
Beware of bugs in the above code; I have only proved it correct, not tried it.
Donald Knuth, March 22, 1977 [5]
Programming
Testing can only prove the presence of bugs, not their absence.
Edsger W. Dijkstra [citation needed]
Programming
[This] reminds me of a quotation from somebody that, whenever he tried to explain the logical structure of a programming language to a programmer, it was like a cat trying to explain to a fish what it feels like to be wet.
Saul Gorn, quoted by Julien Green in Microprogramming, Emulators and Programming languages, Communications of the ACM, Vol. 9, No. 3 (March 1966), pp. 230-232
