G'Day,
It is time for us to do the next incarnation of our products and as part of
that we are looking to ditch the BDE (/ ADO). Essentially our operating
environment is as follows:
- Extremely hostile and remote. ie. Applications are running on machines
that are very difficult to access either physically or with remote access.
- Machines are prone to being abused ie. powered down due to power failures
etc.
- Machines are used for "real-time" applications such as providing data
capture for live sporting events
- DataSets are "smallish" +/- 20 tables with some tables having +/- 5000
records
- DB access is multi user with an upper max of +/- 10 concurrent users
At present we have our apps running using Paradox / BDE. Naturally we have
our fair share of corruptions etc. So we are looking for an alternative that
would satisfy the "Holy Grail"
- Not require the deployment of DLL's for data access (a la BDE)
- DB should be self healing to fix corruptions etc.
- DB should allow easy restructuring should the data definition change
- Still provide SQL access to the data
- Provide TDataSet interface so that existing DB aware controls can be used
easily
Now having said all of that it appears that DBISAM from ElevateSoft fits the
bill exactly. Other players in the market appear to be Appollo, Advantage.
What I would like to know is:
- How do these products stack up in the real world? ie What have been your
real world experieces?
- How well do the products scale in a multi-user environment?
- How well do the products scale as database size increases?
- How well have DB aware controls worked. In particular the Dev Express (esp
Quantum Grid) components?
TIA
