Object databases are different from relational databases which are table-oriented.
DuckDB is special amongst database management systems because it does not have any external dependencies and can build with just a C++11 compiler. [11] DuckDB also deviates from the traditional client–server model by running inside a host process (it has bindings, for example, for a Python interpreter with the ability to directly place data ...
(Microsoft has since added additional APIs.) At about the same time, Sybase introduced a more powerful successor to db-lib, called ct-lib, and called the pair Open Client. db-lib, though officially deprecated, remains in widespread [quantify] use.
