The detailed system design is illustrated in Figure 2 above. There is need to identify the land
administration business processes (Kurwakumire, 2013b) and the user requirements. The results are
used to modernize the business processes. At this stage there is a need to develop a conceptual
schema for the proposed digital cadastre which is used as the basis for developing the logical and
physical model. The conceptual schema shows the different entities and the relationships that exist
between them. The system boundaries are defined at this stage. In the logical stage, key attributes
are identified including the primary keys for each entity or class and foreign keys where required.
This stage is still software independent. Operations to be performed by each entity such as
calculating the area from the parcel geometry or calculating the time a particular person held title to
a parcel of land are devised at the stage. With the information provided from the conceptual and
logical modelling it is then possible to design a prototype which is software specific before a full
scale system can be deployed. The prototype application should be tested within and outside the
DSG to obtain initial user feedback for use in improving the design. Upon improvement, the
prototype goes through many cycles of retesting and improvement until it is ready for full
deployment. Thereafter, the system should be maintained and modified through use of user
feedback.
