Load testing is primarily concerned with testing that the system can continue to operate under a specific load, whether that be large quantities of data or a large number of users. This is generally referred to as software scalability. The related load testing activity of when performed as a non-functional activity is often referred to as endurance testing. Volume testing is a way to test software functions even when certain components (for example a file or database) increase radically in size. Stress testing is a way to test reliability under unexpected or rare workloads. Stability testing (often referred to as load or endurance testing) checks to see if the software can continuously function well in or above an acceptable period.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is called to test software functions when certain components increase in side?
Ah, so.. Volume testing

The relational model also allowed the content of the database to evolve without constant rewriting of links and pointers. The relational part comes from entities referencing other entities in what is known as one-to-many relationship, like a traditional hierarchical model, and many-to-many relationship, like a navigational (network) model. Thus, a relational model can express both hierarchical and navigational models, as well as its native tabular model, allowing for pure or combined modeling in terms of these three models, as the application requires.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the relationship called in a hierarchical model?
Ah, so.. one-to-many

Saint Helena is divided into eight districts, each with a community centre. The districts also serve as statistical subdivisions. The island is a single electoral area and elects twelve representatives to the Legislative Council of fifteen.
