I am working on a data warehousing solution involving mysql and have a question about best practices. We are standardized on mysql 4.1, and this is for a rather picky client.
We have a relational transaction database that stores the results of customer calls and a dimensional reporting database used as a data mart by several applications. Each night, we run a process that aggregates the number of calls, the subjects of each call, and various other data to populate the reporting database. We would like to move to a real time solution, and are struggling with the best way to implment it. What we are considering is a solution where we mirror the transactional database and repopulate key tables in the reporting database every minute or few minutes. I am loathe to do this, mainly because it would add to our server load and could possibly lead to 'dirty reads' (i.e. where one table in the reporting database is populated with fresh data but others are not). At the same time, the client is demanding we implement something. Does anyone have any war stories or suggestions for how to accomplish this?
