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...

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.

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...

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...

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...

Abstract
Relational Database Systems (RDBMS) are the most popular database systems today. The relational model of database management emerged from a dynamic database model called DataBase Management System (DBMS). Dbase and FoxPro were the popular DBMS in the 1970’s and 1980’s. RDBMS emerged in the 1990’s. Though RDBMS is a popular form of database management, few appreciate its true potential. Modern applications that allow multiple devices to access and manipulate data are overshadowing RDBMS. NoSQL models such as Hadoop and MapReduce allow document processing which is a feature that the relational model lacks. An in-depth understanding Continue reading...

Input Controls in User Interfaces

Introduction

Input Controls are an integral part in the forms that software applications use for getting information from the user. They are the interactive part of the user interface. They allow a user to perform many functions like typing text, selecting items from a list, uploading or downloading files, and visiting other web pages. These functions are provided by input controls such as text boxes, hyperlinks, drop down lists, radio buttons, and others.

The hardest part of any research project is the analysis. Students often find data analysis difficult because they do not understand which type of tests to use to answer the questions they are asking, don’t know how to interpret the results, or don’t understand how the sample population affects the nature of hypothesis testing (Flick). Given that qualitative data analysis often requires the development of special coding schemes and training of coders to ensure agreement on categories, qualitative research is often viewed as more difficult and less understandable than quantitative research. In Shane, the Lone Ethnographer, the Continue reading...

A database management system (DBMS) is a software application that enables one or more users to access data in a database (Rouse). It manages user requests, making it easier for these users to understand and locate the data they need. It also handles data access by multiple users, ensuring that the operations these users perform do not come into conflict with each other. In this regard, a DBMS maintains the integrity of the data in that it ensures that the data can always be accessed and that it is consistently organized in the manner that it was intended. In Continue reading...

Describe a database using life cycle concepts

Describe a database using life cycle concepts (that is, life cycle of a database)
The database lifecycle is a process that includes the creation of a database, resource allocation, managing the database schema and data. Additionally, the process also includes the performance of the backup, the recovery tasks and decommissioning of the databases.
The first phase of the development is the planning phase. In this phase, the individual designing the database determines what they have, what they want to have and develop a reasonable procedure on how to develop the database. A feasibility study may be needed to ascertain Continue reading...

Question 1

When transforming a logical database design into a physical database schema the first rule is, do not focus on physical storage challenges and the limitations of any Database Management System (DBMS) known. The thinking should be conceptual not physical, always ensure that the integrity of the data model is intact, by honoring business rules. The second rule is to ensure the integrity of the process, by thinking about the structure and not the process to make sure that all the required stages and feedback loops are taken into account. The third rule is to ensure that the whole process Continue reading...

Give five reasons the tool would be useful for green building analysis.

Data that can be obtained from a tool like Athena may be used to generate energy and emission results. The results are then submitted to a GB tool which in turn generates a score that is directly related to material choices. The Canadian green building challenge team has been using this process since 1998.
The GB tool uses a crude calculator in order to have embodied effects. Furthermore, it uses the same input data which is used by those without access to ATHENA or any similar tool. The limitation of this approach is that it is regional sensitive, and Continue reading...

What is in the database? What kinds of information are available?

The database consists of information that is collected, stored, organized and safeguarded in order to permit easy recovery whenever the information is required. Databases consist of information in the form of data, which is again a collection of facts that can be in numbers, dimensions, terms or observations. Hence, databases are made up of tables that contain fields and reports (Reitz, 2004-6).

Business Intelligence and Data Warehouses

The differences between the structure of data warehouse optimized for processing versus relational database optimized for online transactions and summarizing large amounts of data include the following. Data warehouses use partially denormalized schemas so as to optimize performance, but relational databases have fully normalized schemas used to insert, update and guaranteeing data consistency. Data warehouse is updated regularly using techniques like bulk data modification, but relational database is modified by the end user. It is always up-to date and so it reflects the current state of every transaction. A data warehouse query scans millions of rows, for example, finding Continue reading...

Most organized successful businesses have separate databases and/or with data warehouses. Keeping all company information in one database is very risky as it can be hacked by unauthorized people who may use the information unlawfully (Rajesh, 2010).
Having a single database that contains all business information is cheaper; however, the risk involved is more expensive, and most business prefers separating the information. Day to day operations of the business requires the availability of information, and when the data are not separated, it may take a longer time to retrieve the data (Rajesh, 2010). Keeping data in a single database Continue reading...

Database and Network

A database and a data warehouse are somewhat similar in nature as both are databases containing tables and data. But the main difference between the two is that a database records data and a data warehouse responds to major business questions. (Exforsys) Data analysis can be done using a single domain; however, multiple domains are a common feature for many large businesses. A database would only deal with a single business unit, whereas, a data warehouse will deal with and integrate the several business units. Hence, a databases and data warehouses are separately used in businesses.
Companies can make Continue reading...

- Describe the steps that you would use in order to convert database tables to the First Normal Form, the Second Normal Form, and the Third Normal Form
Normalization is an approach of decomposing tables with an aim of eliminating redundant data and ensuring that data dependencies make sense through logical arrangement and storage. Normalization of a database allows handling and update of the database. Data storage should happen once to avoid storage of data that can undergo calculation from existing data in the databases. It prevents data loss. During the normalization process, removal of redundancies is important. Following Continue reading...

First defined in the year 1970 by Edgar Codd of IBM’s San Jose Research Laboratory, rational database is a database that has a collection of tables of data items. Initially, they were designated and systematized according to the relational model. In other words, relational database represents the database management system (DBMS). It was initially introduced by E. Codd, and it has turned to be a predominant choice for the storage of information for instance in the financial records, manufacturing, personal data, and logistical information (Whitehorn & Marklyn, 2007). It is on record to have substituted the legendary hierarchical databases Continue reading...
