“A database
is an organized collection of data. The data are typically organized to model
relevant aspects of reality in a way that supports processes requiring this
information.”
This is Wikipedia’s description of a database. So, a
database is a set of data that has a systematic structure, and that is
organized in such way that a computer can easily find the desired information.
The data is a collection of pieces of information, mainly information that has
been organized in some specific way for use in analysis or making decisions.
With BIM becoming the primary method of
design process, the building industry is changing. BIM is database building.
All the materials have so much information linked into them. One example could
be how databases estimates material and labor costs for the whole building.
The use of database-based building design
reduces the labor time. Earlier on one actually had to draw each line to create
a window, but now, with programs like Revit, you open the component database
and simply load a window. The window will then become a family, which can be
changed throughout the design process, and all the windows will change with it.
Earlier on, all the windows would have to be re-drawn. The family will also
contain information such as dimensions, material properties, offsets etc. that
can be put directly into sheets and you’d have a whole list of for example all
the windows in the building and their size.
I have used
databases a lot in my internship at a design office. When we should meet the
Danish building regulation's requirements for window area/floor area, it was
very easy to use the sheets in Revit and get all the rooms listed with room
numbers, area, and window area, and then export all the information into an
Excel sheet and calculate the window area/floor area percentage. It was a very
fast process, and that way the architects could sooner know whether they should
increase or decrease the window size in the different rooms.
I used the database’s information, when we should meet the LEED requirements
for a huge banking office of approximately 46000 m2 (495140 ft.
2 (I put both so it wouldn’t just look like a huge calculation error)).
All the windows were angled differently according to their position of the sun.
It would have taken me weeks to measure the different glass percentage area,
but with the Revit schedules, all it took was just a few clicks.

Steve: Great database history! I can't even image a world where databases are "flat". Guess a lot of new technology came from Codd's relational database theory!
Andrew: Very interesting post. I had never heard of SQL before I read your post, so thanks for enlighten me.

Did you find any research that said how databases have improved the work done by design firms? You reference BIM, what type of information can BIM store/how is that utilized specifically by the design firm, or is it information that will make the construction progress more efficiently, etc.?
