Modeling unlimited validity

The reliability and security of the entire time-delimited system directly depend on the accuracy and quality of the data stored in it. The main emphasis is placed on the accuracy of individual values, undefined states, incorrect states, and validity limits.

As already mentioned, the validity of an object’s state is mostly modeled using a logical and physical time interval definition. The implemented solution contains two timeline values expressing the beginning and end of the validity concerning the interval representation. The start of the validity is commonly precisely specified. Therefore, it is necessary to know exactly when the validity of the new state begins. The end point of the validity can be more complicated. If a synchronization layer is present in the system and the data is modified with precisely defined time periodicity, the validity of each state can be clearly defined. However, the problem occurs when the data change is asynchronous...

Ever wonder why speech recognition systems don't understand the Scottish accent, or what would happen if an astronaut only ate mac 'n' cheese, or other spurious reflections you'd have at a bar?
