Data management is a term used by researches and other companies to describe to the architecture and practices used in data mining and even storage.Different people may be used who may use different methods in storing or mining the data.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 important because it protects and monitors the lifecycle of the dataA 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 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.Sometimes it involves removing numbers that are out of range or even aligning the data in order. Another aspect related to data cleaning is consistency, where you ensure that the data is consistency such that there is no anything that is out of place, such as dates and currency.
Data quality is yet another important aspect of data management. This is known to be the aspect of ensuring that the data truly reflects the actual picture in real world. Data that is deemed to possess a high degree of quality normally reflects the true situation in the real world. Low quality data nor show the real world situation.
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 currently place discourages modifications but allow replication or copying.
Database management. 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 has the powers to do the changes and input the data, while the user cannot have such rights.
