“algebra of Systems: a Metalanguage for Model Synthesis and Evaluation”

so we are able to obtain a direct access to the field which our instructor works on; the second is that it focuses more on mathematical theory and simulation of the process of designing, something that the previous papers about the concept of database rarely mention. I learn much from reading this paper, including the algebraic theory, technique for simulation, and the application of the methodology. The algebra discussed here is different from the linear algebra we learned in the freshman year and the relational algebra we learned from E.F.Codd. As far as I'm concerned, the algebra here is a more general idea that other forms of algebras can generate from it with additional constrains and information. The two vital things in algebra are operand set and operator set, and as long as arbitrary compositions of operators on elements in operands result in elements in operands. It is easy to understand using Euclidean space. The operands in a Euclidean space are vectors, and the operators include addition and inner product.
