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.This is very important in ensuring that the data is kept safe through the various ways and process.A lifecycle is a process from collection upto analysis to the point where it is finally used.
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 is a term used by researchers to describe the process of removing unwanted elements within a data set.one can remove non correspondent data in the data set in an effort to ensure that the data is clean. Consistency is another area closely related to data cleaning whereby, there is assurance of order of the data such that the elements such dates follow each other in the correct sequence.
Data management is related to another important component called the data quality. It refers to the process of ensuring that, the data represents the true fact on the ground. High quality data normally is in consistency with the current picture 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. The idea here is to prevent corruption of the data. This is done by use of various means such as use of password and instilling of other measures that minimizes accessibility to the 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.
Data storing and retrieving. This is a concept that is normally used to refer to data storing and retrieving. They work in such a manner that, there must be an administrator and the user. The administrator is the person who puts the data into the data base and has the moral authority and ability to make modifications but the user can only use the data.
