B-tree-based library of C functions. Creates/manipulates indexed file
systems. Standard access method for UNIX. Provides retrieval,
storage and protection.Îïèñàíèå-Ò
Library of C functions that manages indexed sequential access method
files. Allows direct access to records from applications. Offers
X/Open standards compliance, indexing options, data integrity, systems
maintenance and file compatibility. Uses index entries as keys that
point to records. Allows user to find the specific pieces of data
needed, without having to look at extra records. Creates unlimited
indexes for ISAM files. Each index can be from one to eight parts,
with each part a different datatype. Allows user to build indexes on
multiple fields or a single field, and in ascending or descending
order for data in different parts of the same indexes. Automatically
updates records as they are changed. Provides several mechanisms to
keep data safe, including transaction management and logging recovery
features to allow user to recover data should a system or disk fail,
locking mechanisms to manage the concurrency of the data, and a bcheck
utility to ensure index integrity. Offers built-in routines for
transaction management that provide extra security. Logging
facilities help ensure data integrity by recording each transaction in
a log file. Offers locking options that ensure data integrity when
multiple users access the same row concurrently. Records remain
locked until the transaction is either committed or rolled back.
Checks and repairs ISAM index files to further maintain integrity.ÒÅÐÌÈÍÛ
