A CT scan is the test of choice to evaluate for the four types of intracranial hemorrhage (subdural, epidural, intracerebral, or subarachnoid) bleeding in the brain, swelling of the brain during the first 24 to 48 hours after injury, or to detect a skull fracture [4] because it is faster, more cost-effective, and easier to perform than an MRI.
Command and Query Responsibility Segregation (CQRS) is a pattern that segregates the operations that read data (queries) from the operations that update data (commands) by using separate interfaces. This means that the data models used for querying and updates are different.
Figure 1. A possible architectural implementation of the CQRS pattern. In Figure 1, you can see how this portion of the system is split into a read side and a write side. The object or objects or the read side contain only query methods, and the objects on the write side contain only command methods.
