Module closure has two components—access closure, wherein the module and user share no data objects, but only the values of formal parameters, and computation closure, wherein the model which the module emulates is as simple as possible, and implementation independent.
SUMMARY. Information hiding in software design leads to the concept of module closure. The function of modularization in a design is to hide a design decision, facilitating the design of programs which employ that module. This produces a module which may be used elsewhere regardless of its implementation details.
Orthogonality is a system design property which guarantees that modifying the technical effect produced by a component of a system neither creates nor propagates side effects to other components of the system. Typically this is achieved through the separation of concerns and encapsulation, and it is essential for ...

Jan 2, 2017 · Orthogonality is the idea that modules should be written in a way that a change in one module should not require changes in any other module. Two or more things are orthogonal if changes in one do not affect any of the others. In a well-designed system, the database code ...

Feb 25, 2012 · Secondly, Hunt & Thomas's use of the term "orthogonality" focuses on different modules, not design or implementation considerations within a module. More specifically, it has to do with the lack of interdependence between modules. Two modules are orthogonal if changes to one do not affect the other.

As this series concerns CSS , we will stick to study how a CSS can allow to respect this principle of orthogonality. For example, allowing from CSS as ... The CSS must contain the module styles as well as styles of the various states of the module. In an accordion menu, each menu must have two states, eg .is ...
Separation of concerns results in more degrees of freedom for some aspect of the program's design, deployment, or usage. Common among these is increased freedom for simplification and maintenance of code. When concerns are well-separated, there are more opportunities for module upgrade, reuse, ...
In this paper we study properties of orthogonal and orthonormal systems in Hilbert C∗-modules. Actually the theory of Hilbert C∗-modules is at an in- termediate stage between the theory of Hilbert spaces and the theory of general. Banach spaces and can be considered as a “quantization” of the Hilbert space.

We conclude by observing that, if A is either an f-algebra of L 0 type or an Arens algebra of L ∞ type, then the orthogonal complement of a nonempty subset M is necessarily d H closed. This provides a hint for our characterization of complemented submodules. Indeed, by point 5 of Lemma 1, if M is a complemented ...

I characterise various model-theoretic properties of types, in complete theo modules, in terms of the algebraic structure of pure-injective modules. More specifically, I consider the generalised RK-order, and the relation of domination between types, orthogonality of types, and regular types. It will be seen that,.
