The first results of using AMI beta blockers at the hospital were positive and there was an increase of 10 percent within the first two months of use and to 14 percent by the third month. Except for the months of February and March, the compliance with the instructions has been 100 percent with the instructions. During those two months, the physician who had written the initial orders for treatment had not used the established method of using the system of referring to the information technology concerned. If the method had been used, it is estimated by the doctors, mortality would have gone down by around 50 percent which makes a total of 50 lives during an eighteen month period in a hospital with 500 beds. (Quinn; Mannion, 2005) This clearly states that proper maintenance of records and ensuring that patients are treated in the accepted method leads to reduction of deaths. .

             The assurance of quality is a process and the process of quality control is checking that assurance of quality has been maintained. For all data entry, quality assurance has to depend on good standards and procedures backed up by properly configured data entry methods. The main reason for the assurance of good data is data management. Checks are generally carried out through audit of the data against the central data base that exists. Generally all data is now in a single storage with back up copies, and so it is not such a difficult task to check the data against each other. Yet, the question of audit is left to especially trained persons. (Santoro, 1999) .

             The situation today is that databases have become much easier to manage with modern computers and the entire business and healthcare activities concentrate on proper data storage. The earlier systems of storage of data in files are gone and the modern systems are much easier. There are many systems attached to databases for healthcare enterprises including database management, data warehousing and object oriented concepts for databases.
