Abstract


At the present time, some types of database models are considered, in which three types of database models are objects of interest: Hierachiral model, Network model and Relational model. This paper introduces a new model for databases, which called a database model of block form. Some basis concepts and block form - relational algebra are introduced for this model. Some of properties related to keys of block schema and block form - relational algebra are claimed and proved. It is shown that the relational database model is special case of the database model of block form in which each relation is a block with the index set, containing only one element.
