THINK IN MODELS

Before introduce the ideas of model-driven application (MDApp), seems it is necessary to give an illustration for some elements and the relationships in which will be frequently involved. It seems a bit cumbersome but shows many of the view points, see below. The illustration presents the gap between IT and business, as well as computer … Continue reading »

In the work in press[1],  we pointed out an important feature of model-driven application (MDApp), that is, the adaptivity based on models. It is also the meaning of “model-driven” which referred to, it was stated below under the subject of enterprise applications: What business can be handled on the MDApp are what can be modeled … Continue reading »

Smith (1985) depicted how it was connected between computers and the “very real world”; he put computer on the left, real world on the right, then pointed out that “mediating between the two is the inevitable model” (see the post). He also implied that such picture was suitable for human too. I prefer show another … Continue reading »

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 »

In the beginning, the model driven mechanism is a group of principles we summed up in the design of software. Then found that it was a structural fundamental appeared in a wide range of systems, as well as to MDE/MDSD. In the “Presentation on Model-Driven Mechanism in Information Systems and Enterprise Engineering“, mentioned that “MDM … Continue reading »

This is basically an extract translated from my three essays on EE-Forum.org[1] Cognitive (Triangle) Cycle A brain can be considered as an information system. It gains raw data on feeling, makes some theories and programs on thinking, then executes the programs to take actions. there is a simple model for the cognition on brain, so-called … Continue reading »

It is easy to be long-winded when writing with the topic “abstraction”[1]: it seems a bit like a bottomless pit, when I attempt to think about it in depth. Let me make the long story short, to writing some of my conclusions, while it may be a bit hasty. Where the abstract levels based on In the … Continue reading »

A few days ago, I left a comment on Vincent’s blog, with his essay What is the focus of analysis: problem or solution? I said: I always had some doubt to so-called ‘Executable Model’, although it seems an inevitable result in the logic of MDA, but it also like a trap: if the models are … Continue reading »

Last month, I had launched a discussion “What is the essential difference between MODELING and PROGRAMMING?” in the forum of MDSN; I proposed my opinion “Model is not code.” and some of possible aspects for the discussion on the differences between models/modeling and code/programming: – the perspective – the business/problem vs. computer/platform – the interpretation … Continue reading »

In the beginning [1], I chose the word group “model-driven”, which inspired by the concept of “parameter-driven” and “table-driven” in software development. Some the properties would be stored in a parameter-table that can be modified at almost any time, which will be accessed and interpreted at run-time or load-time, and thereby, be able to meet … Continue reading »

The subject is the software or information systems used in enterprise. It is comprehensive, need to support the management and the general business in enterprise, often referred generally as enterprise application or some times, I prefer the term of enterprise information system. In this essay, uses the Enterprise Applications and EntApps for short.   The … Continue reading »
