Parent key

  • the column within a parent table that uniquely identifies rows or records containing the same values.
  • Also known as Primary Key.
  • See also: key

Parent table

  • a table where any row is uniquely identifiable by the contents of a single field (a key); Parent tables are often superior to child tables, typically in a one-to-many relationship.

Parsing

  • separating a character string into individual keywords.

Partial-key retrieval

  • refers to an ASK Index or MDK Index retrieval where a partially specified search argument is used to retrieve one or more records.

Partitioned Databases

  • An Omnidex Databases that has been partitioned into multiple smaller subsets to facilitate retrieval performance.

Partitioned Tables

  • An Omnidex Table that has been partitioned into multiple smaller tables to facilitate retrieval performance.

Partitioning

  • the dividing or grouping of data in a database across storage media such as a disk drive, or across nodes in a distributed computer or network environment in order to speed processes by concurrently processing I/O.

Path

  • Information included with a file name that tells the location of the file. How you specify a path is dependent on the operating system.
  • In Windows, a path is a directory\subdirectory\subdirectory\…filename.
  • In UNIX, a path is directory/subdirectory/subdirectory/…filename.
  • In MPE, a path is filename.group.account.
  • In VAX/VMS, a path is node::device:[directory.subdirectory.subdirectory…]filename.

Pattern matching

  • specifying wildcard notation, for example, asterisks (*), pound signs (#), percent symbols(%), and so on, in a value which represents single or multiple characters in that value.

Port

  • in a computer network, an identifying number that supports transport between a server and one of several clients.

Powersearch

  • Omnidex's PowerSearch feature allows misspellings, synonyms, word variations, phonetics and transpositions during searches.

Prejoined Indexes

Prejoined Tables

  • tables that were linked together during OMNIDEX installation using KEY values declared in the OMNIDEX environment catalog. Prejoining tables optimizes OMNIDEX join operations between them.

Progressively qualifying

  • performing several keyword searches in succession against the same table to narrow the qualified subset of rows. Also called a “drill-down” search.
