This paper describes a general concept of Generalized Class of Objects. Based on this concept, it is possible to construct models of object-oriented spatial information systems, which in fact deal with processing objects belonging to one class only. The Generalized Class is a composite of elements, socalled specialized object components, which are divided into five main groups: descriptive, documents, graphic, relations, and functions. Descriptive components contain non-spatial class attributes. However, graphic components determine graphic representation of objects. Documents make it possible to connect various standard electronic documents (texts, graphic files, sheets, etc) with individual object as well as specialized documents which contain results of specialized analyses (spatial, vector, network). Relation components are implementing all associations between objects including topological relationships such as connectivity or contiguity. Function components are designed for defining specialized static and non-static object methods as well as event service functions, which are called during life of several points of an object, such as object/component creation/ deletion and so on. Each of specialized object components is a specialization of suitable standard object component with suitable sets of standard attributes and methods. These standard methods are responsible for realization of a majority of typical functions which are available in most of current spatial information systems (e.g. spatial or non-spatial data displaying, data updating, data selection or data highlighting). Through such a Generalized Class we can define not only real classes and their relationships but also all system configuration parameters (e.g. coordinate systems, several elements of GUI such as menu bars, toolbars, popup menus, etc). The set of such definitions (set of objects belonging to the Generalized Class of Objects) is a designed system model. It is produced by the CASE tool, so-called System Model Editor. The software of spatial information system is divided into three main layers: System Nucleus, Operating Layer and Specialized Layer. The operation of all binary components belonging to these layers completely depends on system model definitions. The System Nucleus modules make available all low-level system operations to the rest of the system modules, e.g. system resources access. The Operating Layer modules make available appropriate graphic user interface for realization of all standard methods defined in the Generalized Class of Objects. So, when we are ready to use binary components of these two layers, building a new System Model is equivalent to a new version of GIS, completely ready to implement by an end user. During such an implementation, it is simultaneously possible both to fill the system database, as well as to extend the Specialized Layer with new specialized methods in accordance with the end user expectations.
