Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A navigational database is a type of database characterized by the fact that objects (or records) in it are found primarily by following references from other objects. Traditionally navigational interfaces are procedural, though one could characterize some modern systems like XPath as being simultaneously navigational and declarative.Navigational access is traditionally associated with the network model and hierarchical model of database interfaces, and some have even acquired set-oriented features. Navigational techniques use "pointers" and "paths" to navigate among data records. This is in contrast to the relational model (implemented in relational databases), which strives to use "declarative" or logic programming techniques in which you ask the system for what you want instead of how to navigate to it.
