This is an architecture matrix diagram. A matrix diagram is a table that facilitates comparison between different data sets to help with decision-making. It serves as an example of the relationships between the items in pairs from two or more sets, as well as their existence and importance. The matrix will then include a number or symbol in each cell where the two elements meet indicating the relationship between them. A matrix diagram can be used in conjunction with other decision-making instruments. More matrix diagrams can be found and made on EdrawMax.
