Connect:Direct
mainframe computer file transfer software
Connect:Direct—originally named Network Data Mover (NDM)—is a computer software product that transfers files between mainframe computers and/or midrange computers. It was developed for mainframes, with other platforms being added as the product grew. NDM was renamed to Connect:Direct in 1993, following the acquisition of Systems Center, Inc. by Sterling Software. In 1996, Sterling Software executed a public spinoff of a new entity called Sterling Commerce, which consisted of the Communications Software Group (the business unit responsible for marketing the Connect:Direct product and other file transfer products sourced from the pre-1993 Sterling Software (e.g. Connect:Mailbox)) and the Sterling EDI Network business. In 2000, SBC Communications acquired Sterling Commerce and held it until 2010. AT&T merged with SBC effective November 2005. In 2010, IBM completed the purchase of Sterling Commerce from AT&T.
Technology
Traditionally, Sterling Connect:Direct used IBM's Systems Network Architecture (SNA) via dedicated private lines between the parties involved to transfer the data. In the early 1990s TCP/IP support was added.
The public source identifies “Connect:Direct” as mainframe computer file transfer software. This brief keeps that definition visible, then builds a research path around Connect, Direct and mainframe.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Connect:Direct”, the useful work is to connect “mainframe computer file transfer software” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Mar 25, 2026. The linked authority identifier is Q369085. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1993, 1996, 2000 and 2010.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
