Background
Information
Handling Services (IHS) is a leading worldwide provider of technical
standards, specifications, logistics and parts information. The
company provides a wide selection of subscription-based products
in various formats such as the Internet, CD-ROM, and hardcopy.
IHS products serve the critical information needs of many industries
including government, military, automotive, aviation, electronics
and petrochemical.
In
1986, Optical Software Tools (now merged with Doclinx) was one
of the very few companies with the capability to provide full-text
search technology on CD-ROM with acceptable performance. Since
then Doclinx has been awarded numerous contracts for IHS applications
and provides on-going application development and support.
Development
of these products presented unique challenges for the following
reasons:
- The
products required fast full-text search of hundreds of megabytes
of data using 1X CD-ROMs.
- A
complete application needed to be written that had to run under
limited memory available under MS-DOS.
- The
products had to provide parametric search of documents along
with full-text search.
- A
custom rendering and printing system needed to be developed
as the documents were of a complex nature containing equations,
tables and diagrams.
Solution
Doclinx
possessed a very fast search engine that was able to perform full-text
as well as parametric searches and could run directly off a CD-ROM
while providing acceptable search performance. Doclinx analyzed
IHS' processes and recommended SGML as a document format and agreed
to develop applications that allowed indexing, rendering and printing
of the input SGML documents.
In
1986, IHS awarded Doclinx its first contract to develop CD-ROM
based products using the proposed solution.

Developed
IHS
products developed by Doclinx include very-fast retrieval, advanced
search features, change notifications, and document administration
features. Doclinx has developed the following CD-ROM and Web based
products for IHS that use its full-text search technology.
TechDataXpress
(TDX)
The
TDX product is an E-commerce web site for 576,000 standards from
organizations all over the world. This is the first IHS product
that allows true e-commerce of documents. Users can register,
log-on, search for relevant documents, and buy them over the web
using their credit card. The application also supports subscription
users, purchase orders, debit cards and debit accounts.
TDX
is a complete, 3-tier Java Servlets based web application with
features like user registration and authorization, full-text and
parametric queries, tracking lists, document selection, document
change notification, shopping carts and checkout facilities. It
integrates with Oracle 8, Microsoft IIS, Solid RDBMS, and the
TaxWare and CyberCash e-commerce back-end severs. Additionally,
it interacts with various internal IHS systems like IDMS, Data
General Accounting, and Session Manager. The application runs
on two load-balanced four CPU Sun Enterprise 450s running
Solaris 5.6 with two hot backup machines.
World
Wide Standards (WWS)
The
WWS product is a collection of more than 400,000 standards from
organizations all over the world and is distributed on 260 CD-ROMs.
Each CD-ROM contains an application to browse, searchand view
World Wide Standards documents. It has sophisticated drill-down
search and structured query capabilities. The application also
supports NetWare, DiskPort, and NetworkTree.
ASME
Boiler Pressure Vessel Code (BPVC) Application
The
ASME BPVC product is a subscription based, segmented text and
image CD-ROM application. This application provides full-text
search of the BPVC documents, precise rendering and printing of
documents that contain inline equations, tables, fonts and diagrams.
Doclinx built and supports two versions of this application, one
for MS-DOS and the other for Microsoft Windows.
Canadian
Standards Association (CSA) Application
The
CSA product is a subscription based, segmented text and image
CD-ROM application. This application provides full-text search
of the CSA standards, precise rendering and printing of documents
that contain inline equations, tables, fonts and diagrams. Doclinx
built and supports two versions of this application, one for MS-DOS
and the other for Microsoft Windows.
Customer
Benefits
Using
Doclinx's technologies and application development expertise,
IHS was able to bring state-of-the-art products to market years
ahead of its competition. Many of these products are still in
production today and are some of IHS' best sellers. Doclinx continues
to provide support and ongoing development to IHS for these products.
Doclinx
was also instrumental in helping IHS adopt leading technologies
like SGML and Document Ecommerce.
