Data management is the process of collecting, cleaning, analyzing and storing the data in form of pictures, numbers or wordings.There exists different methods and different people to ensure that the process of managing the data is complete.The whole process may not only involve persons, but also softwares that are used for this process mainly used by database administrators and even scientists and researchers.
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 will start with database internal plans, analysis and modeling.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.It is important to do the cleaning of data in an effort to ensure quality. Data cleaning is the removal of unwanted elements within your data set.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 yet another important aspect of data management. It refers to the process of ensuring that, the data represents the true fact on the ground. 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.
Security of the data is the process of ensuring that the so collected data is not vulnerable to corruption and other malpractices that can render the data unusable. 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.
Database management. It is a term that are normally used to refer to the processes of storing and taking the data. It normally consist of the sophisticated user and the common user. The administrator has the powers to do the changes and input the data, while the user cannot have such rights.
