Rule 3: The ratio of true dynamic data (and data being "treated" dynamically) to persistent data is approximately 1:10, and that ratio will rapidly evolve to 1:100 and beyond. Dynamic data just doesn't stay dynamic for very long.

Transactionally oriented systems are all about doing things fast. Perform the transaction fast, store the data fast and load the data into other systems fast. If it sits in a database, it's easy to find, which is the point of a database. The persistent data world is all about finding things. The whole categorizing/ classifying/indexing/search thing is designed to add structure so we can find things. However, it seems to me that if we created two distinct "virtual" places to look for each distinct type of data, it would be a heck of a lot easier to find what we want. If all our dynamic data sat in one place designed to handle things like that and was then moved (based on business rules) into the persistent digital content store, we'd be able to architect this store entirely differently than the dynamic store.

If the dynamic store is about speed and redundancy, the persistent store is about infinite dynamic scale, finding things easily and quickly, and an autonomous self-managing/self-healing infrastructure. It should also be cheap to buy. Stop trying to turn the dynamic store into the persistent one, and also stop trying to make the persistent store dynamic. If you act differently, you'll realize you can get back to making
