RESUMO

The popularization of devices like G PS and wireless network have enabled new applications that collect and analyze mobile objects. Traditional database system do not support the management of mobile object data, since a great amount of information is generated continuously. Research in this area is recent with relatively few works on mobile data management. This Msc thesis proposes an object-oriented mobile object data model that incorporates two characteristics: it supports modeling of static, spatial, temporal, spatio-temporal and mobile objects in a homogeneous way; it specifies a set of basic operators and their algorithmic specification. These operators can be composed to obtain a wide variety of complex operators to query a mobile object database. Unlike most other proposals, this mode supports not only lD object, but also those with 2D geometric descriptions
