Describing Your Production Environment

• Question What is the nature of your production
  environment?
• A large-scale batch file environment?
• One more oriented toward transaction processing,
  where the transactions can affect fields within
  particular records?
• Helpful Quantification to Answer this Question
• How much data are you currently dealing with?
• How many data sources do you have to deal with?
• If your system is file-oriented How many files
  do you get from each source and about how big are
  they?
• If your system is database-oriented How many
  tables are you dealing with and how big are they?
• How complex are the processes you deal with and
  how much code do you have to handle for
  production?

Data Production and Versions

• Classic Text (DL) Context
• Single author
• Produces a few different text versions of the
  same work
• Many (or at least several) nearly identical
  copies of a version
• Software Configuration Management Context
• Multiple authors
• Influence source code production several
  different versions
• Many identical copies of each version within
  release
• Industrial Production (Automotive) Context
• Multiple production processes for single product
  instance
• Large number of variants possible within distinct
  product lines
• Each copy unique with complex assembly of parts
• Scientific Data - Batch Production Context
• Multiple author, discrete deliveries
• Both source code and parameter changes
• Each instance unique, but seek homogeneity of
  errors within large number of instances
