The objective of this paper was to develop a computer application that would allow the various agents of the cadastral division in the city of Lubumbashi and the Director of Land Affairs to register information about the various people who come to apply for land, to facilitate the consultation of information, etc. The application would facilitate the registration of information about the various people who come to apply for land, to facilitate the consultation of information, etc. This application would facilitate the registration of information relating to the various people who come to apply for land, facilitate the consultation of information, etc. This solution is of crucial importance, as it will allow us to avoid the problem of land conflicts which has become commonplace in the city of Lubumbashi. It will also allow the registrar of real estate titles to verify the different plots of land that are available without having to move and in real time.

This work is part of an article developed within the Higher Pedagogical Institute of Lubumbashi (DRC), It leads to the design of the website that will serve as a tool for students of the said institution. Maintenance activities, in the sense of troubleshooting equipment, have always existed. But these activities were initially little or not formalized: they were not necessarily carried out by specialized staff, nor were they supervised by specific methods. In addition, they consisted essentially of repairing equipment; once it was repaired, the repairer was content with the solution to the problem and forgot to archive it somewhere and even if he did, the solution always remained confidential, that is to say, not shared. This collaborative approach makes it possible to transform the Internet into a global forum where the most distant Internet users can meet and form communities according to their tastes and aspirations; and it also allows access to information of common interest, the sharing of opinions... Thus, we admit that the implementation of this tool will certainly help to improve the computer education system and encourage students to have the habit of documenting themselves and the failures encountered for the reusability of the solution and to push students to research, read, share information and stamping. It also aims to help students remedy the various troubleshooting problems they will encounter in their daily lives and put them at the height of a precise diagnosis.
