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). Collection of data items that are structured as a group of officially defined tables from which data can be retrieved in various ways without having to restructure the database tables is known as Relational Database. In relational database, the complete data is stored in tables. The structure of these tables is similar to

When we go about evaluating the Electronic Health Records (EHRs) functionality, standards or certifications, we follow the following usability principles:

- Simplicity: This means information or visual elements that are not necessary to the task are not included in the software package. The functions that are of greater significance should stand out and are easy to understand. The software application should have uncluttered and simple design.
- Naturalness: This implies that the screen metaphors and icons are similar to those other computer application which people or clinicians use. It should also be intuitive such that it is easy learning, and expenditure on training is minimal.
- Consistency: All the parts and terminology of the software has the same look

Interface design and security

Interface design and security

Abstract:

The new system incorporates a touch screen register. The new system is designed to increase security for the registers. Traditional registers operated using a key. Anybody with the key could access the contents of the register. However, there was no way of telling which person was responsible for any action in the register. The design of the new system is supposed to ensure every transaction is logged and is traceable. Cashiers are assigned a user id and a password that they need to access the system. The cashier is allowed a maximum of four incorrect

Introduction

Human-computer interaction (HCI) is a field that seeks to understand how people use computers about the various user interfaces available. Most human-computer interactions use a graphical user interface. However, other interactions make use of speech, sound, touch and command line interfaces (Nielsen, 2003). A principal function of HCI is to understand user satisfaction from using a computer using the corresponding interface (Nielsen, 2003). There are a number of issues that can be measured to determine user satisfaction. These are:

Ease of use

This is a method used to determine how easy the user found it to use the interface. It describes the

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

Our group had edited our paper on Technical Instructions based on the suggestions that we have received from the Usability Test.
On the title, we decided to further narrow down our target audience because just like what the Beta Group had said pertaining to our paper, the topic we want to use is still too broad and will most likely take up more time than what is allotted to us. Thus, we changed our title from ‘How to Use Twitter’ to ‘Twitter for Beginners’.
Because we focused on

Essay

Both authors talk about PowerPoint and Prezi as of two completely different programs, even though both are used for putting together presentations. David Wicks presents Prezi as mainly web based presentation software that is built around the interactive interface with the use of zooming in and out during the presentation, thus, enabling the multiple ways of getting from point A to point B. On the other hand PowerPoint is designed using the linear format, which means that every presentation will go according to a particular script that has only one path of getting to the end; and this is

Introduction

Many people have participated in the development of heuristics for systems to check acceptability for the user of system, one of the best source for this purpose is Nielsen’s Heuristics. Rolf Molich and Jakob Nielsen developed heuristics which were mostly used in the field of user interface design. Nielsen in 1994 refined the list by evaluating sets of heuristics. Nielsen’s Heuristics includes ten points to find out acceptability of user interaction of any system. These points are followings

Introduction

Developing an effective design for a healthcare database is a critical element that enables a healthcare institution to improve its workflow, social interaction, and technology in its operation. However, developing relational database is always associated with pitfalls during developers. There are those common aspects of database design that are being overlooked. Consequently, these pitfalls may harm the entire system (Peden, 2011). Therefore, the database developers should design a database with minimum errors possible. An effective healthcare database will enable the users to effectively examine the patients’ tests, results, history among other variables. Some of common aspects of database design

As a mode of literary criticism, structuralism gained popularity in the late 1950s when the work of Ferdinand de Saussure was translated into English. In chapter 7 Structuralist Criticism of her brilliant book Critical Theory Today: A User-Friendly Guide, Lois Tyson states that before Saussure, the changes of words through time were studied to analyze language. In fact, words were studied in a diachronic manner. Additionally, every word in some represented the object itself.
In the entire context of the chapter, as in to say, keep reading the rest of what she says, what does she mean by this?

Intranet Testing

Intranets have become crucial components of modern business infrastructures and are being adopted by virtually every company. They are used in delivering organizational information, processes and workflows (McHale, 2012). Intranets are developed through accretion, and there is the need to include the organization’s information resources in the development of the intranets. However, issues in the testing of the intranets exist because of difference between the developers and users. These issues can be efficiently be resolved by including both groups in the testing of the intranets.

The best option of resolving the issues between the developers and users is

IPhone 5 and Samsung Galaxy S3 are the latest smart phones in the mobile phone industry. The two products have so many similarities because of their strengths. In one recent poll by users, the IPhone 5 only edged the Galaxy S3 by a slight margin. It is difficult to tell which of the two phones is superior because each of them has its strengths and weaknesses. Therefore, a choice between the two may go down to the consumer’s preference or the purposes they intend to fulfill using the phone. The compatibility of the devices also makes a big

Software design is the process of developing software and applications for different users and for different purposes. A successful software is one that is easy to use and user friendly. It is, therefore, important to study the users of the software, identify their needs and priorities them. Users vary and are of different categories, these users will have different needs and preferences. The attainment of a reliable and a good system is entirely based on the consideration of the user at each step of the design process from the beginning to the final design of the system.

Heuristic evaluation common to human-computer interaction is a mechanism set in place to be used as a standard measure of interfaces by comparing them to predefined set of principles. Often, this evaluation is carried out during development of software, before it’s finalized and eventually implemented. It’s a test to ensure that whatever is being developed surely complies with the set design principles and standards. It’s mostly the aspects connected to usability that are tested, and more precisely factors affecting the application’s interface. Any kind of disloyalty to heuristics identified during the testing and e valuation

Authentication, a most commonly used mechanism to ensure security of systems, is a process of verifying that one attempting to gain access to the systems, is actually legible to. It works by monitoring the user identity information availed at logon and ensuring the identity given is true. However, as much as the sole reason behind authentication is to ensure, it should be made as user friendly as possible (Anderson, 2008).
Mechanisms put in place to ensure user friendly authentication include the two-way authentication and use of biometrics (Quigley, 2005). These, however, have not achieved the full potential to ensure

Discuss the advantages and disadvantages of analytical evaluation.

One advantage of the analytical method is that it can be quickly completed and does not require the participation of users (Rogers et al, 2007). This is especially useful when users cannot be easily accessed or when their involvement will take too much time and be too expensive. On the other hand, its disadvantage is that the results can be considered guesses – such as the time hypothetical users need to complete a given task or the possible usability issues they might encounter during their interaction with the product. This then requires

Usability Testing, Field Studies and Analytical Evaluation

Evaluation is a very important component of the design process. From the user’s point of view, evaluation is needed to see if the product meets their needs. Although, usability of the design is one of the concerns of a user, other factors are also considered by them. They must also be engage in the product and the degree of sophistication the product gives them. In a businessman’s or manufacturer’s point of view evaluation is needed to get feedback from the user to be able to further improve their product. (Sharp, Rogers & Preece, 2007)

Almost all products,

Designing, prototyping and construction

Designing activities in projects starts immediately once some information has been acquired by the design team. It is an iterative process which involves constructing, evaluation and reconstructing the design ideas of the designers to match the requirements of the users. This process of creating interactive versions of ideas either through the use of cardboards, paper illustrations or software programs to model them until such time the whole project is constructed is called prototyping and construction. Designing can mean starting from scratch or modification of an existing design to improve its functionality. (Sharp, Rogers & Preece, 2007)

Prototyping is the process

Discuss the role of field studies in evaluation

Field studies are usually conducted to determine how users adopt a prototype or product in their working and daily lives (Rogers et al, 2007). Unlike usability testing that is conducted in an orderly setting, field studies are conducted in a disorganized manner in that there is constant interruption and overlap in the activities. This more closely resembles the natural settings in which the user would interact with the product in their daily lives.

With this type of evaluation method or technique, it would be possible to obtain information about and evaluate

More and more organizations now acknowledge their human resource as their greatest asset. As Laplante (2006) states, “empowering users with IT boosts the bottom line.” However, IT is useless if it’s too complex and complicated to use. It is then important for employees to be provided with tools that they can quickly and easily learn to use and that they can use to effectively and efficiently complete their tasks.

And Preference Metrics

Interface design has become an integral part of the software development process. It is no longer just enough for a software application to function correctly. It is also now as important for a software application to be usable and to provide users with a good user experience.

To support these usability efforts, usability testing has now become part of the software testing process. With this comes the development of usability metrics, which help software developers and interface designers evaluate the interface design of a software application and make changes as necessary.

Software Usability

Usability is an attribute that evaluates how easily and conveniently customers can use web interfaces. The efficiency of a website is largely determined by its usability[ CITATION Nie07 \l 1033 ]. Websites should be user-friendly and appealing. Users have access to numerous sites through the web and they are hence spoilt for choice. Consequently, it is very unlikely for customers to visit a poorly designed site. A website with good usability is one that is easy to use, one whose homepage clearly states what a business/company offers and what clients can do on the site,

INTRODUCTION

In the world of web design, there are two primary methods of building web pages and links that are utilized – tables and frames. With tables, the entire web page is a single HTML document that displays everything that will be seen by the visitor when they go to a web page. Frames, on the other hand, are a bit more complicated, carrying multiple components and tables on a single page, providing a complex viewing experience for the visitor.

At first glance, it may seem that frames are the better way to go – you can do more interesting things
