 and application development, including commands for database definition, data manipulation, and reporting. All components are accessible by and integrated through a database-oriented programming language. Unlike many tools for managing mainframe data , which are geared to the needs of professional programmers in MIS departments, Nomad is particularly designed for (and sold to) application end-users in large corporations. End-users employ Nomad in batch production cycles and in Web-enabled applications, as well as for reporting and distribution via the Web or PC desktop.

Capabilities

Nomad is distinguished by five characteristics:
  • An intuitive database-oriented 4GL

Nomad's language was designed to simplify the application development process, especially for reporting applications. Where possible, common requirements were addressed by intuitive nonprocedural syntax elements, to avoid traditional programming. The heart of the system was the LIST command, which created report output.

LIST BY STATE BY CUST_ID NAME PHONE ACROSS STATUS BALANCE WHERE STATE AMONG('CT','NY')

State Customer ID Name Phone Active Inactive New
----- ----------- ----------------- ------------ -------- -------- ---------
CT 1001 ABC Co. 203-555-1212 1200 0 0
1012 DEF Co. 203-555-1313 0 50 900
NY 1305 GHI Co. 212-555-1414 2650 0 0


In this example, database fields STATE, CUST_ID, NAME, PHONE, STATUS, and BALANCE are laid out on a grid, with two sort breaks (via BY), generated columns based on data values (via ACROSS), and data selection (via WHERE). Additional keywords could control subtotals, titles, footers, table lookup, and myriad reporting details.

The LIST command is somewhat analogous to the SQL
SQL
SQL is a programming language designed for managing data in relational database management systems ....

 SELECT statement, but incorporates formatting, totaling, and other elements helpful for tailoring output to a business requirement. The SELECT statement, in contrast, is essentially a data query tool: its results would be processed or formatted as required using other mechanisms. This distinction is highlighted by SQL's classification as a 'Data Sublanguage' (DSL): SQL is a powerful formalism for controlling data retrieval. The LIST command is a comprehensive report writer addressing broader functionality.

Another example of Nomad's power is illustrated by Nicholas Rawlings in his comments for the Computer History Museum about NCSS (see citation below). He reports that James Martin
James Martin (author)

." Rawlings offered the following single statement, performing a set-at-a-time operation, to show how trivial this problem was with Nomad:

CHANGE ALL SALARY=SALARY*1.06 WHERE POSITION='ENG' AND AVG(INSTANCE(RATING)) GE 7


Rawlings continues: "[Martin] decided to drop the idea [of showing alternative solutions to the problem]. [The Nomad solution] was too unbelievable for him. He published his book in 1982 [sic: 1981], with many fine examples of NOMAD, most of which look silly today, for they don't reflect what NOMAD was really used for in the years since: serious, mission critical applications. I used Martin's Engineer's Problem in hundreds of NOMAD classes, as I forced people to think in terms of sets of data, instead of record-at-a-time, which is how they'd been taught."

Early development

 competed for many of the same customers, all trying to solve end-user information problems without recourse to traditional 3GL programming.

Nomad was officially released in October 1975 (although customer usage began in May 1975). The Nomad customer base expanded rapidly, as new categories of users adopted time-sharing data management tools to solve problems they previously could not tackle. Nomad competed principally with Focus and Ramis for this expanding market.

Nomad was claimed to be the first commercial product to incorporate relational database concepts. This seems to be borne out by the launch dates of the well-known early RDBMS vendors, which first emerged in the late 70s and early 80s – such as Oracle

 implementation. The early RDBMS vendors were able to learn from numerous papers describing System R in the late 70s and early 80s.

Nomad was released before these industry events, and thus, like System R, Nomad drew on earlier academic work by relational database pioneers such as E. F. Codd. Early Nomad development was in particular inspired by C. J. Date's

). Later editions of the book included Nomad itself, and Date's approval of Nomad's support of the relational database model.

At the time, relational database concepts were new; most database systems utilized hierarchical, network, or other data models. Adding relational features to Nomad's original hierarchical design was evidently a bold move for NCSS. Training materials, such as Dan McCracken's book (cited below), focused on these relational database features, and their use in rapid application development.

 relational databases was soon added to the curriculum – and was later taught on campuses throughout the country, in the ACM Lectureship Series, by NCSS emeritus Lawrence Smith. NCSS can thus be seen as an early advocate of relational methods; but this position was soon eclipsed as SQL-based vendors burst onto the scene.

Development: Late 1970's

Nomad was the flagship NCSS product during the firm's years of rapid growth, going through a series of releases and receiving a major share of this (publicly-traded) company's R&D, sales, support, and other resources.

for the contemporary mind-set). Because of development backlogs, outside services like NCSS became attractive. Tools like Nomad made end-users self-sufficient: If they had discretionary budgets, and could get the necessary raw data from their MIS departments, then they could solve their own information problems. Many users were content to answer seemingly simple aggregate reporting questions that baffled the MIS departments of the day – like "rank departments by profitability." Other end-users went beyond basic reporting to build large, mission-critical applications, either by learning the necessary skills, or by hiring their own technicians who didn't report through the MIS hierarchy. NCSS developed a large support infrastructure, including training, consulting, and other services, to foster end-user independence.

[More citations are needed to illustrate: MIS departments of the 70s and 80s; the "Information Center" concept and end-user empowerment in the 80s; the timesharing industry and its role in enabling what became known as "Agile Companies" capable of using information as a competitive advantage. These topics were widely discussed in books and media of the day.]

In the late 70s, NCSS developed a 'mini-370' product called the NCSS 3200, primarily intended as an in-house platform for running Nomad under the NCSS operating system VP/CSS
VP/CSS
VP/CSS was a time-sharing operating system developed by National CSS. It began life in 1968 as a copy of IBM's CP/CMS, which at the time was distributed to IBM customers at no charge, in source code form, without support, as part of the IBM Type-III Library...

 (see below). The small, low-cost system was sold as an end-user 'database machine' or 'information warehouse' for extracting and analyzing corporate datasets – analogous to the dedicated mainframes installed at some of NCSS's larger customer sites. Despite limited success, the company lost interest in the 3200 venture, which was scrapped along with the VP/CSS operating system.

Development: 1980's

Until 1982, Nomad was available only on NCSS's proprietary time-sharing system VP/CSS. During this period, with a few exceptions, Nomad was used only by interactive time-sharing customers via pay-as-you-go dial-up access.

This changed, marking the start of a new era when Nomad was made available as a separate product under VM in 1982 and under MVS in 1983. It is still available today for the latest versions of z/VM

 operating system. QLIST was added to the mainframe product line, providing a user-friendly environment for developing sophisticated reports without extensive knowledge of Nomad syntax. Nomad remains an extremely stable product that is enhanced to keep up with contemporary needs, such as access to Oracle and SQL Server data on mid-tier platforms, full e-mail support and additional types of output formatted in HTML, XML, and PDF.

A new line of products began later in the 1990s, starting with RP/Web. This was the precursor to UltraQuest Applications, giving users the ability to Web-enable their mainframe Nomad applications. The UltraQuest Reporter product was added to this line-up late in the 1990s, for easy reporting from the Web or from a PC of mainframe data via Nomad. The experience gained from developing and supporting the QLIST and Report Painter products was applied to the development of UltraQuest Reporter. Their influence is clearly visible in UltraQuest Reporter, but Reporter uses Java and HTML technology to create a more user-friendly environment and provide more services.

The basic philosophy of the Nomad language, to simplify the application development and reporting processes with an intuitive and powerful syntax, is carried forward into the UltraQuest products. UltraQuest Reporter applies a layer on top of the 4GL to make report-building even easier, without writing any syntax at all, employing an intuitive and powerful graphical user interface. Other features and services make reporting applications and data securely available through the Web to any employee’s PC.
