Data management is the process of collecting, cleaning, analyzing and storing the data in form of pictures, numbers or wordings.They include various ways and even different persons and practices are used.They may not only consist of persons but also database systems that are used by administrators and scientists.
Here, we shall consider the different aspect of data management from analysis, storage and replications.Data management is vital in ensuring that the data’s life is kept safe.The life of the data is a term that can be used to describe the process where the data is first mined, then taken through the various means until the point where its uses is no longer needed.
We wil start with data modeling, planning and finding of meaning.Data analysis is finding or getting meaning to the data that is stored in the computer.
One of the first aspect to consider is the data quality.Cleaning of the data is just one of the many aspects of data quality. Data cleaning can be described as the process of ensuring that the data only contains the most important aspects that have only been collected and not any other.one can remove non correspondent data in the data set in an effort to ensure that the data is clean. Another point is consistency of the data which can be described as a method of ensuring the data is accurate in terms of dates and other things such as currency and the order of questions.
Data quality is another aspect related to the data management. This is known to be the aspect of ensuring that the data truly reflects the actual picture in real world. This means a data that is of high quality reflects the true situation on the ground. On the other hand, low quality data normally is the opposite or do not match the situation in the real world.
Keeping the data safe is ensuring that there is minimal access to the data by all people that can either cause damage to the data or cause additional changes that are not important. This is always intended to improve the quality of data by minimizing alterations. One can ensure the security of the data by installing passwords and other control mechanisms that have the ability to restrict data modifications and access to the same data. Some of the applications that are used in this work are made in such a manner that, they ensure no modifications to the data, but they can allow one to copy the same data to other applications.
Database management. These are terms used to refer to the process of keeping and using the data. They work in such a manner that, there must be an administrator and the user. The administrator is the person who inputs the data and later and is in a position to do changes and alterations, while the user only uses the data and cannot be able to do any modifications.
