We have investigated the database systems in several popular statistical packages. To handle more diverse types of data, many state-of-the-art data access technologies have been adopted to the new versions of statistical packages. One of the typical characteristics is that most systems provide direct and transparent access to data. We survey and compare those new functions. Also we propose our own system that allows seamless integration of data access capabilities with statistical packages. The system is modular and component based.
