OO Conceptual Schemas Requirements Engineering n 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 People Involved: Emilio, Hugo, Alicia, Margarita, Luis 8

User Interfaces Requirements Engineering n 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 n Class Diagrams Message Sequence Charts (MSC) n State Transition Diagrams n Navigational Model People Involved: Juan, Hugo, Alicia, Margarita 9

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 10

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 n – Navigational Classes – Relationships (Context and Contextual Dependence) People Involved: Oscar, Silvia, Juanjo, Sergio, Ricardo 11

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 12

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 13
