Meier Consultan t Escondido, This Program Booklet is being made available prior to a National Computer Conferencefor the first time. We hope in this way to provide you with information to stimulate your interest in attending the 1975 National Computer Conference. We know that our in-depth technical program will attract a large worldwide audience of computer professionals. I would like to welcome all of to the 1975 NCC and to encourage you to participate in the broad range of activities outlined in this booklet. The National Computer Conferencecan now be said to represent all the computer-related Professional Societies. This year we are joined by the Data Processing Management Association. They now join our other sponsors: The lEEE Computer Society, The Association for Computing Machinery, The Society for Com- puter Simulation and the AFIPS group. As members of the AFIPS group there are eleven other constituent professional societies which have a voice in the National Computer Confer- ence. These members are listed on the front of the booklet. The Institute of Internal Auditors is a new member ofthis Volunteers, for a Conference of this magnitude, number in the hundreds. Practically every committee member, session partici- pant, and organizer belongs to one or more of the member societies. Although society affiliations are not listed, for the most part, their member support has been outstanding. To these AFIPS societies and their participating members, heartiest thanks. To the NCC Board and the NCC Committee, my thanks for your confidence and support. To the AFIPS Staff and to members of the '75 NCC Steering Committee, thanks for your dedication and time and effort. For all attending, thanks for coming. Our extensive technical program, the total exhibit with its range of new equipment and services, and the other numerous activities outlined in this booklet, when combined with the Anaheim Convention facilities and locale, should make your attendance most interesting, productive and worthwhile. We offer you an outstanding program — it's now up to you to participate in NCC '75. 3 Ca. you group. my your papers. Nearly Technical Program As usual, the Proceedings include the presented Chairman's Message all of the sessions will be taped and cassettes made available to aid in the distribution of information. A few select sessions will be transcribed and published as AFIPS Monographs. The entire Technical Program Committee joins me in thanking the hundreds of paper referees, session chairmen, panelists, and area directors who have made this Program Stephen W. Miller possible.

Bemer, Editor Conference 1970 Welcome to the Computer 1975 National Conference and to the Anaheim Convention Center in Southern California. The '70's have been described as the "Decade for Dialogue- referring to the need for increased dialogue technician/designer between the user and of information processing systems. Most technical programs recently have found ways to introduce user viewpoints in order to stimulate this dialogue. One difficulty is the diversity of ' users." To the hardware the suppliers, the user is system programmer. More often "user" application refers to the programmers and operators. Many non-computer people use computers, e.g., problem solvers, POS bank clerks and tellers by simply entering parameters into programs established usually at a terminal, i.e., "parametric users." In tight these economic times a very important class of is manager user the whose budget must support the system. In fact a significant portion of this year's program is aimed at this user/manager who must make dollar decisions about systems development. By mid-decade, a third voice has begun to make its influence that the voice of society via governmentregulations, law and consumer pressure groups. This change, coupled profound with the changes in information system design brought about by the introduction of networks, microprocessors, integrated and data base, make the '70's a period of transition to information systems that are intimately integrated into the very corporate structure and operational procedures of the enterprise and responsive to the requirements of society, i.e., "The of Operational Systems." Era It is our belief that we assembled for a program have technical whose major topic areas match the challenges this new era. We of considered these challenges so important to the information processing community at large that we sought out C nLT °mpetent °"r Professionals to be Technical Area Directors. This sets a high standard of quality In each °' control in each area. case these Technical Area Directors were not only for their technical preeminence, administrative but also for their ability to organize the necessary sessions to bring the most important message from these technical to the attention areas of this diverse, national audience. Most technical areas are treated as a "day" of four sessions in a single room. Many of these start with a tutorial session. Maximum information transfer to an audience frequently occurs when one or two good papers are presented followed by a discussion which is lead by experts in the field. In other cases, professional presentations and bilateral discussions are better suited to information transfer. 4 5 authors, Park, you Bemer, ACM felt; is, suits, you chosen, Keynote Address Conference Luncheon Jay W.
