Abstract
A computer system and method is to store and manage data and to construct application programs. This system accepts uniform input expressions db-terms, by which the stored data can be referenced and user queries can be expressed. A database is a collection of nodes that are connected by a set of directed links. There are three types of links. By ignoring one type of the links, the database can be viewed as a set of trees. All the nodes in databases are viewed as functions; all the db-terms can be computed to their values if they existed against databases and according to computing rules. The tree structures embedded in databases illustrate the dependent relationships among the data, and provide build-in functions in manipulating the database and a theoretical guideline of data distribution. The function-argument-value relationships among the nodes in databases provide a theoretical guideline for a set of useful built-in functions.
