INTRODUCTION
Various organizations tend towards to establish websites, which use databases in order to store, recall, update etc., for specific information. This database can create by using Structure Query Language (SQL). SQL is defined as a query or interpreted language, which depends on using statements via SQL, developing and managing for web database such as incorporate user-supplied data. Moreover, information that store in the database could be high value of:
• Financial secret information such as transactions in banks, users accounts, companies statics
• Private information of some kind information system like patients information in the hospitals, students records in the universities
• Classified data that are related to national security of a country
Besides, the main risk that can find in establishing database is security. This means constructing database that characterizes with unsafe manner, therefore; there is a possible to find a vulnerable in web application, which knows SQL Injection Attack (SQLIA). To illustrate that, if user supplied data is not properly valida...
The next project deliverable is a robust, modernized database and data warehouse design. The company collects large amounts of website data and uses this data to analyze it for the company’s customers. This document will provide an overview of the new data warehouse along with the type of database design that has been selected for the data warehouse. Included in the appendix of this document is a graphical depiction of the logical design of the
Today, you have more reason than ever to care about the privacy of your medical information. This information was once stored in locked file cabinets and on dusty shelves in the medical records department.
In the modern era, the use of computer technology is very important. Back in the day people only used handwriting on the pieces of paper to save all documents, either in general documents or medical records. Now this medical field is using a computer to kept all medical records or other personnel info. Patient's records may be maintained on databases, so that quick searches can be made. But, even if the computer is very important, the facility must remain always in control all the information they store in a computer. This is because to avoid individuals who do not have a right to the patient's information.
A database is a structured collection of data. Data refers to the characteristics of people, things, and events. Oracle stores each data item in its own field. For example, a person's first name, date of birth, and their postal code are each stored in separate fields. The name of a field usually reflects...
Since January 2007, laptop with personal information was lost, email and fax sent to the wrong person, inappropriate disposal of medical record, not to mention the famous telephone call from someone pretending to be patient’s relative (Long, 2012). The confidential data compliance can be very difficult and pointless without a safety net; Hence, the rational of introducing confidentiality.
However, it is essential that there is a better improved electronic health system that protects the sensitive and private information of all Patients. Doctors and medical providers including non medical staff must understand the importance of privacy and how to implement it when using medical records.
the protection of data as well as the systems with the help of Informatics. The significant contribution of
Healthcare organizations are trusted with the most private information of their patients and employees, which has become a top priority in today's world. This involves a legal, a moral and an ethical duty to protect all information of this type by having security and privacy safeguards in place.
The main ethical dilemma in Healthcare industry is access to information and protecting privacy rights of patients. Handling sensitive data about patient information, storing and transferring it from one system to another is an issue. Storing the data files properly is also essential. The healthcare personnel should not have to go through lengthy paperwork just to access a single record. Patients and auditors can ask for access to the information at any time and so the information needs to be transmitted efficiently and safely to them. Similarly, critical information should not be difficult to retrieve also for a doctor. Suppose in an emergency situation like an accident, the doctor needs to access patient records. The doctor should not have to go through multi-factor authentication system in order to gain access to the records.
Inconsistently storing organization data creates a lot of issues, a poor database design can cause security, integrity and normalization related issues. Majority of these issues are due to redundancy and weak data integrity and irregular storage, it is an ongoing challenge for every organization and it is important for organization and DBA to build logical, conceptual and efficient design for database. In today’s complex database systems Normalization, Data Integrity and security plays a key role. Normalization as design approach helps to minimize data redundancy and optimizes data structure by systematically and properly placing data in to appropriate groupings, a successful normalize designed follows “First Normalization Flow”, “Second Normalization Flow” and “Third Normalization flow”. Data integrity helps to increase accuracy and consistency of data over its entire life cycle, it also help keep track of database objects and ensure that each object is created, formatted and maintained properly. It is critical aspect of database design which involves “Database Structure Integrity” and “Semantic data Integrity”. Database Security is another high priority and critical issue for every organization, data breaches continue to dominate business and IT, building a secure system is as much important like Normalization and Data Integrity. Secure system helps to protect data from unauthorized users, data masking and data encryption are preferred technology used by DBA to protect data.
In the past, most of the databases were centralized, protected, and kept in a one location using a complicated database system known as centralized database. Nowadays, with the new technology of personal computers and cell phones, a new sort of database has appeared, and it seems that majority of people are pleasant with it, even if their private data is split everywhere. Many enterprises had changed their databases from the centralized databases, into the distributed database system, since it meets the demand of accessing and processing the data in the organization. Distributed database technology is considered as one of the most remarkable developments in this century (Ozsu, 1991; Rahimi & Haug, 2010; Cain, 2012). Distributed databases are basically a collection of databases that are divided on multiple computers which are connected logically but located in different physical locations, and each site manages its own local data. In contrast, centralized database is a database that is located in a one location and it is considered as a big single database (Connolly & Begg, 2010).
Database & Information Systems is a database used in everyday life, it was used in the past, is used in the present, and will continue to be used in the future. There are single and multiuser databases, as well as N Tier an client servers. There are many types of Data models such as, relational and star schema. Databases and information systems are even used on the web, these types can include PHP scripts and CGI scripts. To understand how Database & Information Systems came about, one has to look at the history of data.
The database application design can be improved in a number of ways as described below:
Moreover, E-commerce has widely recognized nowadays among people. Therefore such data should be secure in databases and privacy of data should be maintained.
The Database Management System (DBMS) is software that enables the users to define, create, maintain and control the access to the database. It is a software that interact with the user’s applications programs and it database. Meanwhile, information retrieval system is a system that involved the activity that the systems obtain the information. The obtaining information action need the information from it resources.
