CQRS is a software architecture pattern in which the responsibilities of a system's commands and queries are segregated by vertically slicing the application logic. You can think of the pattern as a way to separate read and update operations for a data store. The goal of CQRS is maximizing ...
Greg says what it’s not, and since he didn’t use the opportunity to also succinctly express what it is, I helped him out in the comments:CQRS ("Command-Query Responsibility Segregation") is a simple pattern that strictly segregates the responsibility of handling command input into an auton...
Command Query Responsibility Segregation (CQRS) is the notion of having separate data structures for reading and writing information. Strictly CQRS isn't really about events, since you can use CQRS without any events present in your design. But commonly people do combine CQRS with the earlier pat...
In a CQRS architectural pattern, the system is split into two different models: one that handles commands (writing) and one that handles queries (reading). Event streaming can be used in CQRS to propagate changes from the write model to the read model in real-time, enabling asynchronous integ...

What is a data architecture? A data architecture describes how data is managed, from collection through to transformation, distribution and consumption. It sets the blueprint for data and the way that it flows through data storage systems. It is foundational to data processing operations and ...
Ultimately, a database abstraction is a leaky one at best. Your high-level code has to make assumptions about the implementation of lower-level code. Your interfaces don’t protect you here. If you’re “doing DDD” and/or CQRS for example, and you have your aggregate boundaries/transaction...
