I think that this Q post is about collecting data on individuals to sell products. Finding that information is called data mining. Architects refer to computer geeks that build the programs to find and analyze that data, not people that design physical buildings.
Somewhere, computers are collecting data, and using statistics to predict that if you walk into a grocery store to buy bread and milk, that you are very likely to also buy peanut butter. The store would then put the peanut butter next to the bread and milk, and send peanut butter advertising to the computers belonging to anyone that recently bought bread and milk.
I think that the purpose of this Q post is to show that profile data on individuals = $$$.
