I am not to sure of the relevance, but I periodically worked as a sub-contractor for an
Oil-producing Company in California. They were carrying 35 years of data on an Alpha Server
running Ca-Ingres. The really bad part is that hundreds and hundreds of reporting tables were
created on top of the functioning system for reporting over the years. Now nobody know which
tables are relevant and with are redundant and or deprecated.
Also year after year, new custom text file reports were created with procedural scrips. The load
on the server was such that the daily reporting was taking near taking 23 hours to complete. And
the requests for new reports was getting the IT department very worried.
Worst of all know one there really know the ins and outs of Ingres to do anything about it.
Well, I take part of that back. They recently upgrade to a newer alpha to reduce the time daily
reporting was taking. :-)
