Managing unplanned large database is difficult to share data for use or data analysis. Management should start from a discussion of the specific data storage needed for reduce unnecessary information and going in the same direction follow a construction of the same data structure. Using big data to present data should not come from selecting specific information in order to reduce the problem of voluntary choosing the data, which may use the technique of data sampling to be fair in using information for presentation rather than using data from self-selection. There is a process for data validation. Check before recording data rather than using techniques for data analysis. There is a standardized data analysis guideline for everyone to use to analyze to reduce misinterpretation and bias problems or error in analysis. The data analyst should have knowledge and understanding of the subject to be analyzed and understand the purpose data structure details because each person’s understanding of information is different. Protecting the confidentiality and privacy of patient information is necessary for data storage. There will be a system for standardized protection, access to appropriate information and systematic user management to reduce the risk of malware, cyber attraction, virus, hacker and inadvertent disclosure.
