QUESTION POSED ON: 10 January 2005 I have a database developed about two years ago. The database is not
designed properly and the problems are a) there are no indexes, b)
data units repeat in several tables, c) there are no
refrential/integrity constraints, and d) inconsistent data.
There is no database dictionary, or else the link between forms and
tables or fields is not available. The application is large -- about 300
tables and 300-500 forms (VisualBasic). I am looking at the best
approach to migrate this to a new normalized database.
Any suggestions?
I am thinking of using views and "instead of" triggers to aloow me to
create a totally new database and make this change transparent to
application programs.
Is this feasible, and does it sound like a valid approach?
