The current practice of STM is based on keeping track of changes made to the memory and, if needed, restoring previous states in case of transaction rollbacks. The operations in a program that can be reversible,by restoring the memory state, are called transactional operations. The way that this reversibility necessary to transactional operations is achieved is implementation dependent on the STM libraries being used. Operations that cannot be reversed,such as I/O to external data repositories (e.g., disks) or to the console, are called nontransactional operations. Non-transactional operations are usually disallowed inside a memory transaction, because if the transaction aborts their effects cannot be undone. In transactional databases, operations like inserting, removing or transforming data in the database can be undone if executed in the context of a transaction. Since database I/O operations can be reversed, it should be possible to execute those operations in the context of a memory transaction. To achieve such purpose, a new transactional model unifying memory and database transactions into a single one was defined, implemented, and evaluated. This new transactional model satisfies the properties from both the memory and database transactional models. Programmers can now execute memory and database operations in the same transaction and in case of a transaction rollback, the transaction effects in both the memory and the database are reverted.Faculdade de Ciências e TecnologiaLourenço, JoãoRUNDias, Ricardo Jorge Freire2010-10-21T10:21:34Z20082008-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10362/4192enginfo:eu-repo/semantics/openAccessreponame:Repositórios Científicos de Acesso Aberto de Portugal (RCAAP)instname:FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiainstacron:RCAAP2024-05-22T17:07:37Zoai:run.unl.pt:10362/4192Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireinfo@rcaap.ptopendoar:https://opendoar.ac.uk/repository/71602025-05-28T16:38:28.619075Repositórios Científicos de Acesso Aberto de Portugal (RCAAP) - FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiafalse
