Analysis of security techniques and issues in Data Warehouse
The importance of data warehouses in organizations has grown increasingly during this decade, and today they constitute one of the main trends for the development of information technology. Data warehouse system consolidates large data from multiple different sources and these are used by decision makers to analyze the status and the development of an organization. Data warehouses are becoming very vital and beneficial for many types of strategic decisions. Data Warehouse stores large amount of valuable data so it is very important to set a security, from primary stages of data warehouse design so that data must be secured in an effective fashion. Significance of security, security approaches and their issues have been provided in this paper.
Despite the fact that since 1985 the government of Quebec increased by 5.75 % on average the amount of money spent on healthcare per year, little improvement was noted. It is obvious that an optimal use of resources is essential to reduce waiting times and provide safer and faster services to patients. The use of new technology can contribute to improve the healthcare system efficiency. Our study aims to assess the impact of a medication distribution technology on 1) the performance of a health and social services center’s pharmacy, 2) the performance of one care unit in a nursing home and on 3) the medication-use process safety. To measure performance we were inspired by the Lean approach. The results show that medication distribution technology is considered as an effective way to significantly detect medication errors, to allow nurses to focus more on patients and pharmacy to react more rapidly to changes in patient medications.
