Abstract in Portuguese
Os Bancos de Dados Orientados a Objetos surgiram na década de 80, visando possibilitar a representação de tipos de dados complexos, como dados multimídia e conjuntos, entre outros, não representáveis de uma forma direta no Modelo Relacional deDados (Normalizado). Neste trabalho, apresentamos as principais características e alguns exemplos de Bancos de Dados Orientados a Objetos e apresentaremos uma proposta de um modelo de dados, derivado de um Modelo de Entidades e Relacionamentosestendido, contendo a linguagem de declaração e uma linguagem de consulta englobando atributos multivalorados. Como parte prática, apresentamos a conversão de nosso modelo para o Banco de Dados Orientado a Objetos Poet

Abstract in English
The Object-Oriented Databases emerged in the 80's, partially aiming at the representation of complex data types such as multimedia, sets and others, not directly representable through the (Normalized) Relational Model. In this work, we presentthe main features and some examples of Object-Oriented Databases, and make a proposal for a new data model, based on an extended Entity-Relationship model containing the data definition language and a query language accessing also multivaluedattributes. As a practical application, we present the conversion of our model to the Poet Object-Otiented Database model
