Database management systems essay

As DBMSs are often customized to the specific needs of the companies using them, this consolidation does not spell the end of the heterogeneous nature of this market. Organizations' needs are so diverse and the structure of their data and use of applications so varied, that the many vendors in this market are staying relevant and growing as a result. Oracle as a result continues to be in a defensive posture with regard to the economics of open source, hence their acquisition of Sun Microsystems which includes MySQL AB Worthen, Kiviniemi, As a result of these market dynamics, MySQL continues to excel from a technological and user adoption perspective Denton, Peace,

Database management systems essay

The volume, breadth, depth, and pace at which health information is collected have surged. Effective data management is crucial for patient treatment, regulatory compliance, population health, cost management, and quality control.

As a result, the health informatics and health information management disciplines have required greater educational emphasis on data management, governance, quality, and analysis. In this article, the first of a two-part series, the authors present strategies for creating a comprehensive healthcare database course.

Factors influencing course design, such as themes that differ from those of traditional database courses and accreditation requirements, are addressed.

The authors propose minimum and expanded construct sets for database modeling and interrogation, define a minimum feature set for database management systems used for instruction, discuss hosted and individually maintained systems, and evaluate commonly used database management systems.

The result of this work is a framework and methodology for devising a healthcare database management course specifically intended for a health informatics and health information management audience.

They are instrumental in the treatment of patients, hospital administration, regulatory compliance, population health, cost management, quality control, research, and other purposes.

Therefore, the accuracy, timeliness, relevancy, validity, and integrity of the information are of utmost importance. This need is echoed in the global health information technology workforce training program framework of Cortelyou-Ward et al.

This article, the first of a two-part series, presents the methodology behind the creation of the graduate-level course in healthcare database systems at East Carolina University. The methodology is applicable to baccalaureate-level courses as well.

First, the merits of offering a healthcare-centered database course are discussed, followed by discussion of the course design itself. Database modeling and structured query language SQL are elaborated upon, and minimum and expanded construct sets are proposed for each of these topics.

The discussion then moves to the selection of a database management system for the course as well as the benefits and drawbacks of hosted versus individual installations. Part 2 of the series will provide greater specifics on designing a flexible course, deconstruction strategies for database modeling and interrogation instruction, and healthcare-focused sample data sets.

The Divergence of Healthcare Database Courses from Traditional Database Courses Administrators of each HI and HIM program must decide whether to require a database course and, if the course will be required, whether to offer a healthcare-oriented course within the program or use a non-healthcare-focused course from outside the program.

Common substitutes include database courses in computer science CS and management information systems MIS departments. Course content for these replacements is typically stable across colleges and universities because they rely on curriculum guidelines set forth by their respective professional organizations e.

These courses generally cover database theory e. First, whether the course is offered in a CS or MIS department, HI and HIM students will constantly be seeking healthcare analogs to the examples and problems presented in the textbook and lectures.

Although this task appears innocuous, it adds an undue burden to the student and can lead to confusion and even incorrect application. Second, most CS textbooks portray examples and definitions in the form of equations, proofs, and set theory, which are unfamiliar to typical HI and HIM students, decreasing retention and discernment.

Although these topics may be addressed in other courses, applying these rules to actual data sets solidifies the concepts for the student.

Lastly, the data sets, databases, and data warehouses used in these courses are not as complex and standardized as those used in healthcare. That is, healthcare databases store highly diverse and heterogeneous data, maintain standard data sets for reporting and compliance, utilize various data standards and vocabularies, transmit data using different standards e.

Combined, these shortcomings provide a strong fundamental argument in favor of a healthcare-focused database course. However, if offering such a course is not feasible or practical, then a MIS database course is generally a suitable alternative.

Course Design The course design follows the minimalist theory of database instruction. Such environments include the concepts of active learning, theory-to-practice, and scaffolding, which have been repeatedly shown to increase student comprehension and retention of database material.

Minimalist objectives incorporate pre- and postmodule learning outcomes. For instance, one would first describe single-relation operations prior to describing multirelation operations. Error recognition and recovery can be a powerful pedagogical tool in this area. Error recognition and recovery is a process of providing positive and negative examples, forcing the student beyond problem solving to solution finding.

To continue the previous example, the demonstration of single-relation anomalies segues seamlessly into normalization and multirelation operations.

Additionally, one could demonstrate the perils of an unconstrained database by adding, for example, encounters for patients who do not exist, and then trying to produce a bill. These errors reinforce the concepts of referential integrity. Stated simply, the goal of error recognition and recovery is to move from simply solving a problem to identifying errors whether logical or syntactic and providing solutions.

Conforming to Accreditation Standards Accreditation signals to the public that a program has met and maintained an acceptable level of quality as determined by an external accrediting body in the field of study.

Thus, although this article focuses on the graduate-level curriculum, it is also applicable to baccalaureate healthcare database course design.
