EMWAC Database Demonstrator - Access version Installation Notes

(Notes on using the demonstrator are in file readme2.txt)

The following notes refer to installation of the application to
interact with local Microsoft Access databases.  This version
demonstrates the interface but does not interact with remote
databases and so requires none of the communications
prerequisites.

Software prerequisites
----------------------
The development was done under Windows for workgroups 3.11, 
Microsoft Access 1.1.  Operation in other environments has not
been tested.

ODBC or other communication components are not required.

Hardware Requirements
---------------------
The machine used for development was an IBM 486 with 16mb RAM. 
The application should work however on any PC compatible capable
of supporting the software prerequisites.  8mb RAM is the
recommended minimum.  Because this application emulates remote
servers, additional Access databases are required.  The total
space requirements for Access databases are as follows:

     Database:      Acc91pr.mdb
     Purpose:       Main Access application.
     Compressed:    146 kb.
     Uncompressed:
                    400k of disk memory is required to load    
                    the application initially.  This will
                    expand; how much depends on how the
                    application is used; 1 mb should generally
                    be sufficient.

     Database:      C91cntrl.mdb   
     Purpose:       Access database containing dummy Census
                    data.  
     Compressed:    11 kb.
     Uncompressed:  65 kb; does not increase in size.
     
     Database:      C91Dum1.mdb    
     Purpose:       Access database 1 containing dummy Census
                    data.
     Compressed:    670 kb
     Uncompressed:  2.8mb; does not increase in size.

     Database:      C91Dum2.mdb     
     Purpose:       Access database 2 containing dummy Census
                    data. 
     Compressed:    985 kb
     Uncompressed:  3.3mb; does not increase in size

Installation
------------

1.   Application
     The Access database containing the applications is a normal 
     Access database, contained in a single file and is named
     accc91p.mdb.  It can be installed (by copying it after
     uncompressing it) in any convenient directory.  

2.   Dummy server data databases
     There are three of these databases; c91dum1.mdb and
     c91dum2.mdb contain dummy census data and c91cntrl.mdb
     contains control data.  All three operate as is they were
     stored on remote database servers.  They can be installed
     in any convenient directory (after uncompressing them)
     although the default directory for their installation in
     c:\access

3.   Installing server databases in directories other than
     c:\access
     If any or all of the access database files c91dum1.mdb,  
     c91dum2.mdb, or c91cntrl.mdb are installed in a directory
     other than c:\access, the table "Access Database Names" in
     the application will have to be updated to point to their
     new location.  (that table does for the Access demonstrator
     what the ODBC mapping information does for the ODBC
     demonstrator).  To update this table:
     a.   open the database accc91p.mdb WITH THE SHIFT KEY HELD
          DOWN.  
               The "Database" window should be displaying the
               Tables in the database.
     b.   Open the table "Access Database Names" by double
          clicking on the name.
               The Table's datasheet should be displayed 
     c.   Update the "Drive Letter" and "Path" files as
          required; no other fields should be changed.
     d.   Close the table.
     e.   Close the database.

4.   The application can now be opened and started as normal.
