Data conversion from relational to object-oriented database (Q5942496)

The problem of conversion of database from a relational form to object-oriented one according to a process of transformation of the scheme is considered. This is a second stage of the process of transformation of the scheme. The first stage of the process consists of mapping of relations into classes. Two algorithms of converting problems are described. The first one has a low speed of operations but there is not any repeated information in the hole object-oriented database. The second algorithm has an optimal speed but there is possibility to get the repeated information of a considerable volume.
