This Node's function is to provide a persistent data storage and retrieval in support of the user-to-business transactional interaction. The data stored is relevant to the specific business interaction, for example bank balance, insurance information, and current purchase by the user.
It is important to note that the mode of database access is perhaps the most important factor determining the performance of this Web application, in all but the simplest cases. The recommended approach is to collapse the database accesses into single or very few calls. This can be achieved via coding and invoking stored procedure calls on the database.
