What about running Filemaker version 3 (under OS 7.6.1)? It is quite
powerful and only requires about 3 MB RAM minimum. Maybe useful on
those 68030 boxes...

Hi Scripters,

I'm developing a large network and all CGI scripts and network
applications

are being developed using AppleScript. It makes extensive use of
databases,

but the network is being built using multiple low-end Macs (ie.
68030's,

I've been creating proprietary databases where the internal structure

very flexible, with records having only fields that are needed at the

so different records will have different fields. Also, each database

multiple sections (records and lists WITHIN records and lists, and so

My problem is that the time it takes to read a database consisting of
1000

records takes a L-O-N-G time, holding up the operations of the network
for

a minute or so. Simply unacceptable, as this delay adds up with

I've been using 'open for access' to create the files, then 'save/read

data' osax to read and write data to the files. It's works well, but I

can't figure out how to PARTIALLY read a file to speed up the process.

Also, updating a file currently involves reading the entire file to a

variable, updating the variable, then overwriting the file with the
updated

variable. This works well, too, but it's S-L-O-W sometimes.

If you can provide any assistance or tips, I'd love to hear from you.
Also,

if you're interested in working with me directly on this project, I

use the help. Please write me at: Ted Wood <email@hidden>.

Thanks for any help.
