“…There are various spatial Conceptual Models of Data (CMD) among which we state two different approaches: Perceptory [8] and Modeling of Application Data with Spatio-Temporal (MADS) [9] [10]. They are based on CMD that originates from the databases, respectively UML and ER (Entity/Association).…”

The monitoring system based on a sensor network requires large databases due to the storage of measurements without checking their redundancies. In this paper, we propose an instantaneous spatiotemporal data model based on object-oriented concepts that considers the possibility of tracking data from different objects (sensors) for periodic or instantaneous events. Each sensor must record its measurement only when a significant change is applied to it. With our model, we have subdivided the save sets into several sub entities to minimize the space occupied and save only the relevant information. This approach allows to manage the saving of different data according to the needs of the user or the phenomenon to be monitored. It also reduces data redundancy and facilitates the execution of queries.

This paper focuses on the design of a Decision Support System for Course Material production and inventory management in the National Open University of Nigeria. The proposed system has a model base management subsystem which is a component that differentiates Decision Support Systems from other types of Information Systems. The model base consists of a wide collection of models which include inventory models, production quantity models and a forecast model. Other components of the system including the data management subsystem, dialog generation and management subsystem and the users of the system were also discussed. A prototype of the Decision Support System was developed using python programming and MYSQL database server. Testing and validation was done using sample data of students’ enrolment and user defined inputs for the forecast, inventory and production modules of the system. The results of the tests show high level of accuracy when compared with those obtained from manual computations. The design is simple, flexible and can be easily modified to suit the needs of other institutions with multi-item inventory problems.
