    A delimited text file is a text file used to store data, in which each line represents a single book, company, or other thing, and each line has fields separated by the delimiter.

The file is simple. A flat file can be a plain text file (e.g. csv, txt or tsv), or a binary file. Relationships can be inferred from the data in the ...

  7. Database index - Wikipedia

    en.wikipedia.org/wiki/Database_index

    The primary feature of a clustered index is therefore the ordering of the physical data rows in accordance with the index blocks that point to them. Some databases separate the data and index blocks into separate files, others put two completely different data blocks within the same physical file(s).

  8. Naming convention (programming) - Wikipedia

    en.wikipedia.org/wiki/Naming_convention...

    Common practice in most Lisp dialects is to use dashes to separate words in identifiers, as in with-open-file and make-hash-table. Dynamic variable names conventionally start and end with asterisks: *map-walls*. Constants names are marked by plus signs: +map-size+. [29] [30]
