- I have a very large database which I am putting onto a Macintosh using 4th
- dimension. It is initially about 40-45 mb, and it will increase by about 250
- mb when I get the historical data into it. Thereafter it will increase at the
- rate of about 45 mb per annum.
-
- Now, I don't really need to keep the database on a mainframe, which is more
- expensive (both in running costs and development costs) and takes longer to
- develop the system. Also, the time taken to run reports isn't really an issue.
- I am happy to set the reports off in the evening and pick them up the next
- morning.
-
- Nevertheless, I would like to keep the database as small and fast as possible.
- Since we only report on historical data occasionally, I thought I would keep
- history on a tape, and copy it onto a disc when I need to use it. I also
- thought I would keep a separate database for the most recent two years.
-
- But I was wondering if anyone has some thoughts on ways to manage historical
- data. Sometimes I will want to report on time periods which overlap years
- (hence I have one big historical database instead of a few smaller ones - is it
- possible to overcome this difficulty in the new version of 4th dimension?).
- Any ideas on managing large databases on a pc would be appreciated. Also, any
- ideas on designing a faster database would also be of interest.

- Thank you for any assistance

- Paul.
