Model Driven Multimedia Development Description

Modeling has traditionally been an important part of the multimedia software development process as it allows developers to tackle complex problems by using abstraction and hiding technical details. A models goal is to predict problems early on in design phases to avoid problems during implementation. Since defects can be detected earlier on in the software development process, the use of models reduces maintenance costs. Model-based software development is used for more than just visualizing the code or design of the system; it is used to produce source code directly from the model. Traditional model management and service system which is the key component of DSS only supports the single format model in the special application field. Based on requirements of multi-model-aided decision, this paper designs the general model management and service system which provides the general management and service for different format models on network. The system proposes the solution to manage different format models by providing model frame generator which aims to analyze decision problem top-down and model application frame which aims to integrate model function bottom-up.
