What Access Server Does
Access Server is the HP 3000-based data server in Information Access, an
information retrieval system that gives PC users access to PC data as
well as to files or IMAGE databases on the host HP 3000.
Access Server is supported in MPE/V environments on Series 3X through 7X
machines, and in MPE/XL environments on Series 9XX machines. The MPE/XL
version of Access Server is in Native Mode to take advantage of the
Series 9XX system architecture.
The Database Administrator (DBA) controls what data is available to each
user through Access Server. The DBA provides further security by
specifying which portion of that data each user can access. Access
Server users are not allowed to alter IMAGE databases in any way, but
they can overwrite MPE files. (KSAM files cannot be overwritten.)
Secondary DBAs can be appointed by the primary DBA and given authority to
control specific access groups, users, data sources, and tables.
Together, Access PC and Access Server let the PC user:
* Access local PC databases such as CONDOR, dBASE II, III, III+, and
IV, R:base 4000, 5000, and System V, R:base for DOS, and Executive
Card Manager (ECM).
* Access local PC spreadsheets such as Lotus 1-2-3 and Symphony.
* Access host IMAGE databases.
* Access information in host files.
* Access remote files and IMAGE databases on networked HP 3000s no
more than one node away from the host.

NOTE To the PC user of Information Access, "remote" means
anything that is not on the PC, which includes the host HP
3000 and other HP 3000s networked to the host HP 3000.
In this manual, the term "remote" indicates a networked HP
3000. It does not indicate the host HP 3000 except when the
reference is to a specific Access PC function label.
(See "Lesson 1: How Access PC and Access Server Work" in
the Information Access Server: Learning the Administrator
Utility manual for more information.)

* Combine information from data sources, regardless of their
location, while maintaining MPE and IMAGE security.
* Access non-relational data as relational tables (tables with rows
and columns of data), a format familiar to most PC users.
* Select only the data needed for viewing and manipulation.
* Sort and summarize table information.
* Save and/or print the results of table manipulations, either on
the PC or host HP 3000.
* Upload tables created on the PC to the HP 3000.
* Abort long operations on the HP 3000 with a CANCEL command from
the PC. Status messages on the PC provide information about the
estimated time to completion.
* Initiate batch jobs from the PC and continue with other tasks
while the batch job executes on the host.
* Reformat result tables for use in popular PC applications.
Result tables can be downloaded directly to CONDOR, dBASE II, III,
III+, and IV, R:base 4000, 5000, and System V, R:base for DOS,
Symphony, Lotus 1-2-3, and ECM databases, or converted to DIF
format for VisiCalc, to ASCII for Microsoft (R) Word, Executive
MemoMaker, and other PC word processors, or to QB (Quoted Basic)
for R:base, Lotus 1-2-3, and custom applications.
* Reformat result tables for use in HP 3000 applications.
Result tables can be converted to DIF, SD (self-describing),
ASCII, binary, and BRW/IRF file formats.
* Create and print reports from result tables with the Access PC's
Report Writer facility.
* Use IMSAM keyed access to IMAGE databases enhanced with Dynamic
Information System Corporation's OMNIDEX Information Management
System.
