Hi all,

I am currently designing my first database. The complexity is
manageable. However in the future I might want to expand the domain to
time-series and as far as I understand time-series and databases don't
go well together. How does this relate to the object-relational
mismatch? I have seen that there is some research, e.g. H.Darwen's
Temporal Data and the Relational Model, but don't have the time to
study those things in depth. Basically I want to avert bigger problems
later on. Should I research the theory more before starting
implementation or can I adapt as I go along?

     How do you expect to avert problems later if you do not know what
you are doing?  Read first.

Read first.  In particular, download the Rick Snodgrass book from the
the University of Arizona website.It is the classic for doing temporal
queries in SQL.
