Abstract: A connector includes a casing, a circuit board, a joint and an adapter. The casing has an accommodating space. The circuit board, located in the accommodating space, has multiple conductive contacts. The joint, assembled on the casing, is electrically connected to the circuit board. The adapter module, detachably assembled in the accommodating space, includes a first body, a second body and multiple piercing terminals. The first body has multiple insertion slots. The second body is combined with the first body. The multiple piercing terminals, located on the second body, correspond to the insertion slots and are electrically connected to the multiple conductive contacts.

Abstract: A method for discovering association rules in an electronic database commonly known as data mining. A database is divided into a plurality of sections, and each section is sequentially scanned, the results of the previous scan being taken into consideration in a current scanned partition. Three algorithms are further developed on this basis that deal with incremental mining, mining general temporal association rules, and weighted association rules in a time-variant database.
