Hierarchical and Network Data Models
... Hierarchical and network DBMS are considered outdated and are no longer used for building new database applications. They are much less flexible than relational DBMS and do not support ad hoc, English language–like inquiries for information. All paths for accessing data must be specified in advance ...

Multidimensional Access Methods: Trees Have Grown Everywhere
... The optimization of composite procedure execution is an important issue, which constitutes a relatively undeveloped field in the research area of spatial databases. The term “optimization”, although commonly used, is a misnomer, because in many cases (especially in non- conventional DBMSs, like geog ...
