Data modeling and database design

Making use of database systems would benefit a health care organization as information regarding a patient can be retrieved easily and quickly Choobineh & Lo, 2004.

The initial design of the database is vital to ensure that information is accurate and logical. Patient information can be easily retrieved and shared with other professionals. Information sharing becomes easy, and health care workers can collaborate with others irrespective of location. Using different descriptions for the same data in a database will create confusion especially when the information has to be exported to another system. The database system would treat the description differently and create a new field for storing the data. This would result in confusion when the data is retrieved by other health care workers. During the design phase, the health care workers should be consulted in order to establish their preferences and collate the information. Health care organizations have different ways of storing information. One health care facility could store its patient's names under one field while another would separate the fields into first, last, and surname.

Creating a blueprint for the required data, assists the designers to create logical presentations of the data captured Mantha, 1987.

Logical data relationships are vital for the database. When users query the database they expect to receive accurate information, but in some instances there might be conflicting information because of the database design. Health care organizations use database systems for capturing and storing patient information. This ease the burden and risk of losing patient records. In case the patient needs to be referred to another facility, the organization would submit the patient's records electronically.

Data modeling reduces the development time of database systems. Data modeling provides the designers and developers with a thorough understanding of the source systems. With this understanding, the developers are able to conceptualize the system and develop the system rapidly. There is improved accuracy of the results. The designers of the database would have understood the requirements and the system will deliver results and information as required by the end users. Parsons (2002)

posits that data modeling provides for increased transparency. The health care workers will have enough transparency, to enable them realize the available information. This is beneficial as the health care workers might not be aware of the information they can retrieve from the system. Knowing that information that can be retrieved from the system would allow the health care workers to make full use of the system. In most health care organizations, workers are not aware of their systems full potential. They only make use of the simple queries, but if during the data modeling workers could be shown the extent of information they can retrieve they would appreciate the system.

If the data models are not flexible enough to accommodate future changes any small enhancement would result in a major rework of the whole system, this according to Dekleva (1992)

would also result in increased costs for maintaining the system. The data models should be checked to ensure that they have the capability to be flexible in case of any….....
