        <p>Object-oriented databases are less common than relational systems, but
are still fairly widespread. Most object-oriented databases were
originally conceived as persistent storage systems closely wedded to
particular high-level programming languages like C++. With the spread
of Java, most now support more than one programming language, but
object-oriented database systems fundamentally provide the same class
and method abstractions as do object-oriented programming languages.</p>
