?Databases are used in a variety of industries, specifically speaking in health care. This paper will address how databases are used across the health care industry. It will examine the architectures and discuss the relational model in detail. The needs of databases users in health care will also be explored.
             In today's information age, data is increasingly driving healthcare decision making. Healthcare databases consist of data that reflect clinical and clinically related information. The data are usually collected through the routine processes and activities of patient care; however, its usefulness goes beyond the operational applications that generate the data. The documentation within health care databases is often used for quality improvement, patient safety and security, improved decision making, and preventing redundancy. Healthcare databases facilitate the organization by facilitating, organizing, storing, and processing large amounts of data.
             Across the health care industry databases are used in many ways. Databases are used to reimbursement purposes for payment; they are popular among payments from the Centers for Medicare and Medicaid. There are databases used for specific diseases that are prevalent in health care. When there are outbreaks and incidents of diseases in specific areas, health care databases are used to pinpoint the geographic locations. Databases are also used in clinical practices. They are useful for billing, keeping patient records, and automating sensitive information.
             There are many database architectures that have a table or more; they have the ability to store data in a large capacity. Differences in the architectures lie in how the records and tables are related. Popular database models include: hierarchical; network; object- oriented; relational; and entity relationship. The hierarchical model was created in efforts of creating a hierarchy of upside down trees. The concept of it shows a r...
