| - | Partitioned Databases | ||
| - | ==== Partitioned Tables ==== | + | ==== 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 | ||
| - | ==== Powersearch ==== | + | ==== 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. | ||
| - | ==== Prejoined Indexes ==== | + | ==== Parsing ==== |
| + | * separating a character string into individual keywords. | ||
| - | ==== Prejoned Tables ==== | + | ==== 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. | ||
| - | **parent key** | + | ==== 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. | ||
| - | * the column within a parent table that uniquely identifies rows or records containing the same values. | + | ==== Port ==== |
| - | * Also known as Primary Key. | + | * in a computer network, an identifying number that supports transport between a server and one of several clients. |
| - | * See also: key | + | |
| - | **parent table** | + | ==== Powersearch ==== |
| + | * Omnidex's PowerSearch feature allows misspellings, synonyms, word variations, phonetics and transpositions during searches. | ||
| - | * 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. | + | ==== 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. | + | ==== Prejoined Tables ==== |
