Abstract

Decision-making is process physicians do in various aspects of their professional care provision endurance. However, the critical nature of decision-making in the health sector makes physicians vulnerable. The best decisions yield the best quality in care provision. In this context, the formulations of decision support systems have been an aspect of concern in the contemporary health care society. The numerous cases of physicians making wrong decisions and jeopardizing the quality of care have been a topic of criticism that could be effectively solved by these decision support systems. A comprehensive analysis of various case studies depicting the success and Continue reading...

The purpose of creating a database that can maintain records of patients in any given area is so that one can find out which vaccines have been administered to the people and which vaccines still need to be given. One needs to remember that this is a particular schedule which needs to be adhered to in relation to administration of vaccines for children, as well as adults. (Missouri Community Guide State Team Final Report, 2011)
This would be an excellent initiative which would help regularize the administration of vaccines and also help curtail the spread of controllable diseases. However Continue reading...

The accuracy of the information that health organizations use is a critical asset to the healthcare decision making. The decision made should be based on identification and assessment of appropriate data sources done within the boundary of the data of interest and its availability. The healthcare information is extremely critical as it primary; contains demographic information from admission, medication uses, discharge and treatment of all patients. The health data also contains coronary anatomy and intervention from the laboratory module (Lichtenstein 2004). In addition, health data is obtained directly from the patients, therefore, gives a true reflection the state of Continue reading...

Article Review

This article provides a discussion of the application of Object-Level Keyword Search Over Relational Databases (OKSORD). This has been prompted by the difficulties associated with the application Keyword Search Over Relational Databases (KSORD), which makes it difficult for the end user to understand. The procedure discussed for developing an object level data model for the Object-Level Keyword Search Over Relational Databases involves the classification of relation algorithm into four categories. This is then followed by converting a relational database schema to an object-level schema graph. The final step involves generating an object level data graph for the object level Continue reading...

The data management process for a researcher consists of two parts; the data collection process and the analysis of the information gathered. The researcher must first begin by identifying the sources of data collection and determining which of these sources would be the most appropriate and reliable.
The various sources of data can either be primary or secondary. Primary data refers to raw, original data that was collected at the time of the event. Therefore, it allows the researcher to study the data up close. Secondary data on the other hand, offers an analysis on past data, it may Continue reading...

Extreme input and output techniques refer to techniques of managing and controlling inputs and output scales in data processing and other processing units. This regards implementation of parallel applications that help reduce risks involved with events tracing on extreme scale inputs and outputs (Smallwood, 2005).

Smoking is known widely as the primary cause of cancer of the lungs but a lot remains unknown on the etiology of lung cancer. The study involved a pooled analysis of standardized covariate and exposure data from 7 different prospective studies comprising 3137 lung cancer cases and 399,767 participants. In terms of collection of information, the authors collected information by pooling cohorts, which were arrived at using the criteria of incident lung cancer cases, dietary assessment, a validation Continue reading...

Introduction

Structured Query Language (SQL) injection is a code injection technique used in requesting, deleting and updating information from databases. Therefore, it is one of the main web attack mechanism used by hackers to steal data. This attack allows the hacker to inject SQL commands into allowing them access data in a database, as it takes advantage of improper coding in the web applications. This kind of attack bypasses firewalls and endpoint defenses, because web based forms must allow access to databases so as to give some sort of response.

Impacts of SQL

SQL injections pose a serious threats to database servers in Continue reading...

Software development life cycle (SDLC) is process through which software’s or systems that are designed developed and implemented (Roebuck, 2012). Proper SDLC methodologies can be used to improve quality of datasets. This can be done through by selecting the best SDLC methodology, which is achieved through learning the SDLC models, assessing needs from all stakeholders and then defining a criterion to weigh and establish the best model to implement, (Chao, 2006). This criterion must meet the threshold for the taskforce in the design, best technology in resolving the problem at hand, compatibility of the methodology to resolving the Continue reading...

A database or a databank is an application where data can be stored and retrieved quickly. It is also important to know how the data is stored and organized in a database. Database mainly refers to a relational database, indeed a Relational Database Management System (RDBMS).

NETW206: Introduction to Switching

In practice, it is common to interconnect switches to achieve redundancy. When switches are interconnected, the network is redundant and cannot fail even if one of the connected links gets faulty. This is a common technique in computer networking. However, this interconnection introduces serious problem in the network known as Layer 2 Switching loop. Layer 2 traffic is traditionally classified as unicast, multicast and broadcast. Unicast, multicast, and broadcast are varieties of network communication mechanisms required for the normal operation of the network. In the case of multicast and broadcast in MAC, for instance, the switch needs to forward Continue reading...

There are steps that are involved in developing an Entity Relationship Model. The first step is to identify the entities that will be used in the model. The entities are the objects that will be defined and have the relationships in the data model developed. The next step would be to define the relationships that exist between the entities that have been defined. The relationships will define the direction in which the relationship between the entities will take. They will guide in the creation of the database. The third step would be entering the attributes. Attributes are the characteristics Continue reading...

An auto numbered primary key does not give an accurate count of records since it acts as a counter. This makes it increment records hence may not give accurate values. The access database uses different data types. These are date time, auto number, OLE object, text, Yes/No and number data types. The date time data type allows for calculations based on time. The auto number data type generates primary key values. The OLE object data type allows one to store complex data. On the other hand, the text data type stores both text and number while Yes/No uses a Continue reading...

Introduction

Data is the building block of any system in the world today. A repository of such related data is called a database. A relational database organizes the data into tables that are related to each other. For example, in a relational database system, there exists one table that contains the data about cars manufactured by a company and the second table contains the information about car parts. These tables are related to each other, because each car is made up of parts, and each car part can be in one or more cars.
Haley (1991) defines a table as Continue reading...

Increase in the use of internet has increased the vulnerabilities of databases for many corporations. Prior to 1970s, much of the research and early work has been in the statistical database security (Thuraisingham 55). The most important accepts in statistical database security involve aggregation and inference (Gollmann 168). Aggregation relates to examining the differences in sensitivity levels of an aggregate computed for a group of values in a database and the sensitivity levels of individual elements. Attackers usually use the differences in sensitivity levels to have access to the sensitive items in the database. When it comes to inference, Continue reading...
