On Models and Domains for Model Driven Applications

A Concept of Model Following last post, here concentrate topic on the models for model-driven applications (MDApps). First, clarify that in what sense use the term model. The suggestion is stated at Model as Use: we call an entity model while it plays the role in the situation where the entity has and provides a set … Continue reading

On Some Main Kinds of Models in MDE/MDSD

Models and modeling are inevitable and pervasive, this seems it has become a common sense of the community of model driven engineering (MDE) for a long time. For example, in a recent post, Marco Brambilla has highlighted that “you cannot avoid modeling.” Earlier, Jean Bezivin has written at here, said the main idea of MDE … Continue reading

Can Zhu Bajie Be a Fashion Model?

Zhu Bajie is a famous monster in Chinese mythology, half man and half pig.  Can he be a fashion model too? See the declarative sentence, “she is a woman” and “she is a model”, in which “is a” has different meanings: the former means that she is essentially a woman; the latter means that she is … Continue reading

Models Make Us Running on the World

A person has to face reality, a computer as well. No matter what you faced think by yourself, from a third party view, it is the world. So-called face is first to touch it, to watch it, to listen to it, to sniff it – to feel it, then, to make certain reactions to the world … Continue reading

Stats on Using Frequency of Some Words (Model etc.) by Google Scholar in 2000-2011

Description The using frequency in literature, especially in the title of articles, is an objective reflection of the importance to a word. The Google Scholar has a quite great and neutral mother data, It is very well to such the statistical investigations. To observe the using frequency of “model” and other some general words in … Continue reading

Wartofsky: “anything can be a model of anything else!”

In “The Model Muddle: Proposals for an Immodest Realism”, Marx W. Wartofsky said[1]: There is an additional trivial truth, which may strike some people as shocking: anything can be a model of anything else! This implies that between any two things there is at least one property they both share. It reminds me of the … Continue reading

Stachowiak’s <M, O, K, t, Z>: a case for model as use

In the General Model Theory[1] Stachowiak defined a n-tuple with model[2]. It appears that very consistent with the definition on model as use. Stachowiak defined <M, O, K, t, Z> as a n-tuple of five parameters (of which) comprising an object O and a model M representing the functional operation F, M= F(O). The object … Continue reading

Simplification (Abbreviation, Reduction) is Not the Essential Feature for Concept of Model

It seems widely recognized, simplification (or abbreviation, reduction; it also very related to abstract, see this post) is an unquestionable features to the concept of model. In my opinion, however, it is not absolute or necessary but just a widespread feature of model. It is absolute to just some sort of model, for example, the … Continue reading

Model as Use

These days, I participated in some interesting discussions about Visual Thinking and model, and saw the proposition on the blog of Model Practice: “essentially all models are wrong, but some are useful” by Scott E. Page in the online lecture Model Thinking, and the comment by the blogger (|=), “without being ‘wrong’ (i.e. loosing details) … Continue reading

Models would not be Failed

The recent discussion on the success of MDE/models faded out soon in our eyes. Of course, it is important that what is wrong or what is insufficient and how we are going to do, such as Jean Bezivin pointed out in his speech (an introduction), that might be just a beginning, I think. An assertions are … Continue reading

Some Basic Topics and Judgment of Ownership to the Three Spaces

The three spaces (Physical Space, Conceptual Space, and Computational Space[1]) can be regarded as a reference frame or basic background, while discussing such the topics in below. The most basic question would be how to judge the ownership of a thing, among the spaces. Firstly, it needs to repeat that, the default context are computer … Continue reading

Have Models failed?

“Models have filed,” Jean Bezivin said[1], “at least temporarily. […]The deployment of MDE seems today to have reached a standstill.” Anyway, this is a rather heavy judgment, I don’t know whether it’ ll stir up some waves (I hope so) in the MDE community which appears a little dreary and lifeless. However, what factors led … Continue reading

Talking Models and Domains to Enterprise Applications

In Some Classification of Models for Software Applications, I explained some classification on the models which are relevant to software applications. Some of the models and domains were shown in the Fig. 1 of the essay. I will try to illustrate it more but before starting, do some improvement for the expression firstly. See the … Continue reading

Modeling on Black/White-boxes, and Abstract Level

The concept of black/white-boxes The term black-box is usually referred to a device, object or system[1]. The concept of black/white-boxes implies an assumption, that is, the view or description of a system under study [2] is able to be separated into outer or inner aspects. The outer aspect involves such as functions, behaviors, or characteristics, … Continue reading

Some Classification of Models for Software Applications

In Models: Execution or More, I cited some Ed’s view points on models. In my view, it appears there is a dichotomy between executable models and non-executable models (of course, I am not sure if it is fitting Ed’s idea). On the other hand, there are two basic aspects for modeling: the application system and … Continue reading
