Hello all,

I am facing the following task: I want to benchmark different
solutions for storing large amounts of finite element data from
different simulations into one file that preferably resides in a local
directory. One option of course is to stuff everything into one binary
file. The other option is to use a DBMS. There is also a hybrid
option, namely to store binary chunks into a DBMS, however, I guess in
this case I do not take advantage of any relational data structures. I
find it hard to figure out why most vendors use inhouse "database"
systems instead of widely used commercial ones. Do I miss something?
Any info, experience or redirection will be highly appreciated!!!
