8. 8 Requirements Engineering n This research area is oriented to the study and definition of Requirements Engineering Methods that are capable to obtain Conceptual Schemas in an automatic way. n Function Refinement Tree n Use Cases n Sequence Diagrams n Class Diagrams n People Involved: Emilio, Hugo, Alicia, Margarita, Luis OO Conceptual Schemas

9. 9 Requirements Engineering n This research area studies how to obtain user interfaces from the system requirements specification. The requirements are collected using specification techniques as Use Cases. n Use Cases n Class Diagrams n Message Sequence Charts (MSC) n State Transition Diagrams n Navigational Model n People Involved: Juan, Hugo, Alicia, Margarita User Interfaces

10. 10 Software Patterns and Code Generation n This area develops a methodological framework that incorporates software patterns in the software production process. It provides a pattern-based automatic software production method. –Specifying Conceptual Patterns –Creating Pattern Languages for Conceptual Modeling –Applying Design Patterns to Automate the Code Generation Process n People Involved: Vicente, Manoli, Eva

11. 11 E-Modeling n This area proposes a software production method for WEB environments. This method is mainly applied to develop electronic comerce applications. –Navigational Maps –Navigational Contexts –Navigational Links –Navigational Classes –Relationships (Context and Contextual Dependence) n People Involved: Oscar, Silvia, Juanjo, Sergio, Ricardo

12. 12 Software Quality n This area proposes techniques to measure the quality of a software product. It provides quality attributes and metrics to evaluate the software product at the Problem Space (Quality of Conceptual Schemas) and at the Solution Space. –Quality of WEB Sites –Quality of Conceptual Schemas –Metrics: OO Function Points and WEB Function Points n People Involved: Oscar, Silvia, Rafa

13. 13 Distributed Objects n In this area software technologies based on distributed objects (like COM+ and CORBA) are applied to the software production methods (OO-Method in our case) n People Involved: Jaime, Oscar
