| Περίληψη | Web transactions may be complex, composed of several sub-transactions accessing different resources including legacy systems. They may also have complex semantics. To deal with complex web applications, transaction design methodologies and tools need to be very flexible allowing for designing web applications from scratch (top-down design), as well as using existing systems or services to compose new applications which offer added value services (bottom-up design) to the user. In this paper we describe UTML as a high level transaction design language to facilitate the complex web transaction design process. UTML is based on a transaction meta-model, which can describe, in a flexible and extensible manner, most of the known transaction models as well as new ones according to the application’s requirements. It provides modeling for transactions that incorporate different behavioral patterns, and it is capable to describe activities with weaker transactional semantics that they do not have all the ACID properties. Unlike other models, it can be used to synthesize new transactions from pre-existing transaction systems (like legacy systems), with diverse transactional semantics. UTML provides a rich notation to visualize the design process using UML class diagrams to model the static structure of transactions and UML state machines to model their dynamic behavior and their flow of execution. | en |
