The design of BODC's databases have developed over the years to
support the evolving nature of data collected by the science of
oceanography. - Oracle Relational Database Management System
(RDBMS) - National Oceanographic Database (NODB) - Project
Database - Web Database 1. Oracle Relational Database Management
System (RDBMS) Our databases adhere to the relational model of
database design and have been implemented using the Oracle
Relational Database Management System (RDBMS). The databases
contain tables which are used to store information. Tables
consist of columns and rows. Sometimes a column is called a
field and a row is called a record. Each row should be unique
and can be identified using a primary key. A primary key is made
up of one or more fields. Tables can have relationships or links
with other tables. A value (e.g. a parameter code) stored in one

table. This approach helps to minimise duplication of
information. Figure 1 illustrates the r
