Abstract: Logical schemas are used to allow an end user the ability to access and manipulate relational database data without knowledge of the structure of the relational database. A logical schema is first created specifying which tables are available to an end user, and the relationships between columns of those tables. The logical schema defines a structure for the data fields having a master level and a plurality of detail levels. An end user may manipulate the logical schema using a graphical interface to build customized forms, reports, and queries. An end user is not required to be familiar with a database query language, such as SQL, or the structure of the relational database.

Abstract: The hand held device of the invention is adapted for cutting, reaming and bending tubing. The device includes as discussed above a bender body member having a tubing guide track, a bender bracket having a bender flange, a rotatable cutting wheel, and a reaming tool. The bender bracket is connected to the bender body member. The reaming tool is connected to the bender body member. The rotatable cutting wheel is supported by the body member. The bender flange is positioned above the tubing guide track so that tubing fed beneath the bender flange is held by the bender flange as the tubing is bent into the tubing guide track. The upper work surface of the tubing guide track is semicircular in cross section. The tubing guide track is arced. The bender flange has a tubing engaging portion which is semicircular in cross-section. A work portion of the tubing is positioned in the tubing guide track beneath the tubing engaging portion of the bender flange.
