Introduction
Data management has been a headache to many technology enthusiasts for quite a long period of time. They have successfully managed to logically collect interrelated data and share it. If the data is in large volumes ad it has to be access by many people differently, it becomes a challenge. The distributed database management system was then developed to avail information to all users efficiently as if from one distributing system. This paper analyses the various uses of the DDMS and its respective advantages and disadvantages.
The DDBMS
The DDBMS is simply a software device that can store and manage data in a centralized manner. There are very many databases available in different geographically distributed across the world. A DDBMS is technically designed to distribute and mange this database as if it were from one device or computer. It can therefore be taken to be a collection of many interrelated and interconnected databases which get physically distributed all over the world through a centralized computer network (Lin et al., 2015). The former has numerous uses across the many sections of life that large volumes of data need to be sorted and accessed.

The software provides users with a vibrant opportunity to create, insert, delete or even append files and other forms of records. A major reason that makes it very useful is the fact that a variety of its data is independent, as most of the tech engineers require. The data is physically stored over the sites without depending on each other. It lacks a multiprocessor hence the processors are then connected via a network. It is used for periodic synchronizations of databases which is factor vital for making the various data distributions transparent. Transparency is what most of those accessing data require (Davidson, 1984).
Advantages and Disadvantages
The new system of distributing data has incomparably great advantages over the traditional mode; the centralized systems of databases. The latter however, has quite some disadvantages, as expected. The importance’s, nonetheless, have overwhelmed the disadvantages. A variety of organizations and large institutions have many branches. For instance, banks can have various places where they are distributed.
In each of those branches, they might want to share its databases among them all; minding that they are in different locations. For instance, the information’s about their customers are essentially needed to be availed to all branches. The distribution systems therefore come in handy to distribute such databases as is from one centralized location, sorting them independently ( Kandasamy, 2018) . This makes it best for reflection of organizational strictures .
Failures in data centralization, access and transferee can be tragic to some if not most of the institutions. The speeds and efficacy of the centralized systems make them more reliable and efficient when it comes to data sorting and availing of databases. It is also one of the most important software for availing the needed data a section that the centralized system failed.
Organizations can have different geographical distributions which can be reflected by the various distributions of its data; data stored in one site can be accessed in various sites in the organization. Such data is mostly placed close to those who access it the most. It therefore provides them a better chance to manipulate it according to will. This shows the advantage of the distributed systems n the section of the improvement of its local autonomy and the share ability.
Since the data is located nearest to the place where it is highly needed, with the application of the DDBMS parallelism, the speed of accessing and controlling the database gets immensely improved ( |., 2018) . This is made better by the implication that each site handles only a part of the entire database. This system has also been termed economic since it is cheaper to a system network of smaller computers than creating one large centralized computer .
The fact of the distributed DBMS being able to hide its nature from the user, while at the same time giving good levels of performance, reliability and availability, makes it very complicated. Not many people tend to understand its complexity when they view the manner of it being able to replicate data; a fact that if not properly handled would make the software a total disaster.
Replicated data in DDBMS can be controlled in various locations making its information security questionable. This serves as a great disadvantage if vital and sensitive information falls to the wrong hands. The DDBMS has been reported to lack standard giving it a potential that is significantly limited ( Kandasamy, 2018) . Nonetheless, not all people have the same level of the understanding of its protocols making it a difficult entity .
Conclusion
The distributed DBMS was a perfect replacement of the centralized system. It allows for a transparent distribution of database across different locations. It makes the access and manipulation of quick and reliable. Most of the organizations and institutions rely on the DDBMS for proper availability of records across their branches. It, however, poses quite a complexity to most of its users.
