The distribution of water and the billing of user consumption remain a major difficulty that the Régie de Distribution d’Eau of the Democratic Republic of Congo, REGIDESO in acronym, has been trying to overcome for several years, because this does not allow the Congolese State to maximize revenue on the one hand, and on the other hand, users are victims of over-invoicing, classified in the category of flat-rate invoicing, given that REGIDESO has no effective means of management of water distribution and users. In the context of the province of Lualaba, in the city of Kolwezi which presents a fast demographic growth, and which knows many problems related to the management of water consumption, this study relates to the installation of a system of distribution and monitoring of water consumption using Internet of Things sensors to control and manage installations remotely.

The Geographic Information System ranks among the flagship tools in the approach of new information and communication technologies, and this in land management which, currently, is at the center of several studies especially with the document digitization project. Cadastral in the Democratic Republic of Congo. In the context of the province of Haut-Katanga, through its land division of Haut-Katanga which presents a rapid demographic growth, and which knows a lot of requests for land which sometimes cause land conflicts following spoliations, encroachments and attributions multiples of the plots to several applicants following the mismanagement of the subdivisions which does not guarantee the security of the title deeds. To respond to land management concerns, we are proposing through this study the Geographic Information System and its means of implementation to assess the degree of resolution of land disputes.

The Office of Control of the Congo in particular and of the world in general must avoid the method of destruction of foodstuffs which become unfit for consumption after weighing them to check that the quantity weighed corresponds to the nominal quantity on the Label of the package. We opted for a non-destructive method by using the batch acceptance or rejection test using a dual sampling design. This statistical method resolves the conflict between the Office of Control and the sellers of pre-packaged products of Class A (food products).

Since the advent of computer science, technological progress has been steadily growing, notably with the famous Moore law, which wanted the microprocessor of the next generation to have the dual capabilities of the previous microprocessor. Exponential ways from the advent of Windows 95 with its I-80486 processor, to the pentium4 up to the i3, i5 and i7 dual core processor. The logical consequences of this technological advance is that the various (For those already existing as computer-aided design) and new branches such as special effects in movies, with software like Maya 3D, Blender. Computer-related occupations have seen fields linked to the development of video games becoming industries with high financial returns (up to $ 2 billion in sales). The medical field in neuroscience today sees its future intimately linked to the technology of 3D modeling, computer science has so far created jobs like software developer or companies like Google, Apple, Facebook, twitter, are To this day to the head of huge financial capital and go as far as recruiting developers in most universities around the world. To date, computer science and the progress of science have created a global dependence in the various fields of our everyday life, such as autonomous management software, internet, communications. The future progress of this science is certainly ready, Thanks to its promising potential in the creation of new occupations, while not forgetting its perverse effects, which are the gradual obsolescence of certain current occupations with the risk of unemployment for the least educated and least able to progress exponentially in our modern societies.

This paper addresses a problem of choosing a data structure in the context of managing information in a general ledger. A multicriteria approach is proposed to classify structures for recording and manipulating information to general accounting. A family of criteria is proposed and a ranking approach is adopted to perform this ranking. The results obtained make it possible to obtain a certificate of aptitude for obtaining the best data structure for the management of the information at the accounting. In addition, a sensitivity study is carried out to assess the effect of the variation in weight given to each criterion on the ranking obtained.
