Relational Schema on Database Table Systems Function, Research Paper Example


This discussion and presentation on how a database functions to provide practical information about patients and their condition of recovery intends to show how IT operations could increase the efficiency of service that healthcare facilities provide to the society today. In a way, this discussion hopes to examine the tables and categories of information that a database stores especially in relation to the recovery of patients and how it provides an indication on the quality of service that the establishments of healthcare industries provide them with.


The database storage system table to be examined herein is based on the function of keeping information regarding patients as they are admitted and are released from particular healthcare facilities where they have been admitted to. The database aims to create a connective process by which the healthcare facilities give attention to the possible process of recovery that the patients undergo even after living their territories of care. This allows them to see whether or not the service they have provided has been able to give ease to the health issue that the patient has primarily complained about as he or she has been admitted to their facility. One particular feature that this database posses is the fact that it functions to keep a record of whether or not there is a recurring health case with the patient within the 30 days after the patient’s release from the care of the establishment. The thirty-day leeway is expected to measure the efficiency of service that the patients receive from the establishments and the staff working for them. This record-keeping system does not only aim to create a record for the patients, but also to create a source of measurement of whether or not the healthcare establishments are giving efficient service that makes recovery for patients easier to contend with.

Relational Tables

The tables separating the information encoded into the system categorizes the type of release that the patients are to undergo after being released from the healthcare establishment they have been admitted to. The database then has an input table for the name of the patient [separated between the last and the first name], the number of the patient [which allows the release record to be easily connected with the admission and other medical records of the individual involved], and the type of release which is categorized into two particular types. These types include (a) patient going home with home services [which could involve a visiting nurse or a home-stay nurse] (b)patient going home without service [visiting under outpatient record]. The last column on the table is dedicated to record the thirty-day development on the patient especially in connection to whether or not the individual came back for readmission or any particular condition even relating to simple emergency case.

Primary Key

In this particular table, the primary key is the column where the number of the patient is recorded due to the fact that this particular element shall lead to the overall record relating to the condition of the patient before, during and after the time of treatment and admission to the facility. This is considered to be the primary information needed to access all the other details kept in the database for reference.

Data Characteristics

The data kept in the system consist of letters, numbers and commas as primary punctuations used. Relatively, these characteristics are important in noting the condition by which the database is able to set a categorical separation on each information being encoded into the system.


It could be understood that the data system examined in this paper is dedicated to creating a practical source of information that healthcare administrators could use to further evaluate the level of operation they try to keep on imposing unto their patients thus allowing them to make a name in the industry. Relatively, it could be understood that the categories included in the tables show the concern of the healthcare facilities with regards the results of the services they have given to their patients even after the individuals have left their care.
