Data management may refer to the aspects of drawing plans and culture of collecting and keeping the data.They include various ways and even different persons and practices are used.The process of storing the data may consist of softwares that are normally used to store the data or some may even be used to do the anasysis and coding.
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 getting the meaning to the already collected or stored data in terms of graphing or other means.
Let we now focus on the quality of the data stired.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.Sometimes it involves removing numbers that are out of range or even aligning the data in order. 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. 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. 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. This is a concept that is normally used to refer to data storing and retrieving. It normally consist of the sophisticated user and the common 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.
