Data Design Methods

Introduction

Many organizations and companies rely on databases to run their operations and achieve competitive advantage. Database design refers to the different parts of the design of an overall database system. It can be thought of as the logical data structures used to store data, and the forms and queries used as part of the overall database application within the database management system (Wikipedia.org). The paper focuses on database design methods and steps that can be taken to achieve a good design structure that avoids redundancy, duplicate data or the absence of required data.
The need to understand database models
Databases are important to the organizational setting. Databases allow organizations to share data across multiple applications and systems. Organizations build several databases each one sharing data with several information systems. This is because it is almost impractical to build one database to meet an entire organization’s needs. Therefore data design is critical to the consistency, integrity and accuracy of the data in a database. A database that is improperly designed will make it difficult to retrieve certain types of information. Besides, there is the risk that searches will produce inaccurate results or information that may have potential damaging effects on a company's bottom line. Inaccurate database may also affect the daily operations of a business and its future direction. A good database addresses the informational and operational needs of an organization and is advantageous because it yields accurate information, helps to store data more efficiently and effectively and also makes it easy to manage and maintain the data (Whitten, J . & Bentley, L, 2007).

Types of databases
A database is an organized collection of data used for the purpose of modeling some type of organization or…...

Business Data Analysis- Fennal Design

...Module code: BSS002-6 Module Name: Business Data Analysis Submission: 30 November, 2012 I my class I learn how to simulate data to solve a problem. I learn to use excel and some function in it these are =SUM() = RAND() =AVERAGE() =STDV() =RANDINV() =VLOOKUP() and few more . These are widely used function when I simulated data in excel. In task 1 I find out how to calculate or forecast how much card should we print. I use a random variable with =RAND( function and use =VLOOKUP() function to find out demand from discreet variable called cumulative probabilities. This is discrete because we find out the range by frequency distribution. Then I use if function to calculate disposable cost with =IF (Demand>Production,(Demand-Production)*Disposable cost, 0). This function works with logical criteria. It says that, if demand is greater than production then disposable cost will be (Demand-Production)*Disposable cost, if not then “0”. Then I calculated profit. Then I simulated 1000 trial with 4 types demand to find out with demand will give us maximum profit and this was $40000. If we print $40000 cards then we can make profit of $57758 which is higher than other. Then we use DATA ANALYSIS add-in to simulate descriptive statistic. From here we can answer question no 2 also. If you print 20000 cards then will make profit of 46178 which is less than what can we make in 40000 printed cards. In here simulated demand is uncertain variable when is used for......

Database and Data Warehousing Design

...head: DATABASE AND DATA WAREHOUSING DESIGN Database and Data Warehousing Design Yolanda McCollum Dr. Constance D. Blanson CIS499: Information Systems Capstone February 11, 2014 Database and Data Warehousing Design Why does one need data warehousing? According to Total Metrics (2013): 1. The prime purpose of a Data Warehouse is to store, in one system, data and information that originates from multiple applications within, or across, organizations. The data may be stored ‘as received’ from the source application, or it may be processed upon input to validate, translate, aggregate, or derive new data/information. 2. Most of the data load functions are processed in batch. There are few on-line data maintenance functions. The on-line functions that do exist tend to update the reference files and data translation tables. 3. A database alone does not constitute a Data Warehouse system. At a minimum, a Data Warehouse system must include the database and corresponding load functions. Data reporting functions are optional. They may, or may not be an integral part of the Data Warehouse system. 4. The prime purpose of storing the data is to support the information reporting requirements of an organization i.e. multiple users and multiple applications. 5. The Data Warehouse may, or may not, provide the required reporting functions. In some cases, external applications access the Data Warehouse files to generate their own reports and queries. 6. Data Warehouse......

Methods of Collecting Job Analysis Data

...Methods of Collecting Job Analysis Data A variety of methods are used to collect information about jobs. None of them, however, is perfect. In actual practice, therefore, a combination of several methods is used for obtaining job analysis data. These are discussed below. Job performance In this method the job analyst actually performs the job in question. The analyst, thus, receives first hand experience of contextual factors on the job including physical hazards, social demands, emotional pressures and mental requirements. This method is useful for jobs that can be easily learned. It is not suitable for jobs that are hazardous (e.g., fire fighters) or for jobs that require extensive training (e.g., doctors, pharmacists). Personal observation The analyst observes the worker(s) doing the job. The tasks performed, the pace at which activities are done, the working conditions, etc., are observed during a complete work cycle. During observation, certain precautions should be taken The analyst must observe average workers during average conditions. The analyst should observe without getting directly involved in the job. The analyst must make note of the specific job needs and not the behaviors specific to particular workers. The analyst must make sure that he obtains a proper sample for generalization. This method allows for a deep understanding of job duties. It is appropriate for manual, short period job activities. On the negative side, the methods fail to take note of the......

...this area is considered the best in the industry. Having a firm sense of the exact problem statement the research completed is trying to solve will be vital to my ability to best interpret and utilize it. Additionally, I would look for would be to determine how well the consultants went about seeking to gain an adequate understanding of the insurance industry, our company history, principles, and values, as well as our goals for the future. To truly serve justice in consulting for our company, the consultants must be thorough enough to understand the sheer importance of getting to know their client in advance of beginning the research itself. Another factor I would seek out is whether or not the empirical standards of the scientific method were utilized in the gather of this research. Our text teaches us that high quality research employs these procedures in order to generate replicable research through the employment of nine key principles. Some of these principles include ensuring the purpose of the research is clearly defined, the research process is detailed and thoroughly planned out, only the highest of ethical standards are applied, the findings are presented as unambiguously as possible, and the researcher’s personal experience is reflected. As this business report would likely contain suggestions for improving the customer experience as our life insurance company, it would be very important to me that I am convinced the findings therein were crafted by......

Design Methods

...Design Methods for decision-making Introduction The figure of designer is a hybrid between the artist, the mathematician an the scientist, but he can not be identify with nobody of this three figures (Jones, 1992). In fact the designer, to take decisions within a project, applies both creative and mathematical methods. The aim of this essay is to demonstrate if these two approaches to the design are more useful and utilized in the effective project or in commercial environment. Thus, to understand what is the reason for which they are used, it is decided to analyse two creative methods, brainstorming and mood board, and two mathematical, evaluation matrix and QFD. What is resulted from the analysis of these two approaches to the design it is that the creative methods are really used by the designer for the project, while the mathematical methods are more useful for commercial purposes and in business environment. Creative methods Brainstorming Brainstorming is a technique very utilized in the design environment, because it allows to maintain wide the project area and because it is a method which can be used in every step of the design process. The word itself can guess what is the function of this method: to produce many ideas quickly (Jones, 1992). Osborn, the inventor of this technique, has dictated very precise rules (Cross, 1994): - No criticism is allowed during the session - A large quantity of ideas is wanted - Seemingly crazy ideas are quite welcome ...

Exploring Different Data Collection Methods

...2015 Exploring Different Data Collection Methods Statistical Methods in Business & Economics (BUS405) Ching Sum Jessie Ha (80600402) Honolulu University 2015 Exploring Different Data Collection Methods Statistical Methods in Business & Economics (BUS405) Ching Sum Jessie Ha (80600402) Introduction Data is collected to learn the effectiveness of a particular tool in preventing defects or to look into the cause of a particular defect (Burrill, Ledolter, p.381). Data removes the trepidation and uncertainty of an unknown element. One reason for collecting data is to gain an understanding of the data by organizing and graphing the individual values (Albert, Rossman, p.1). Secondly, and most importantly, collecting data helps draw conclusions about a larger group of information (Albert, Rossman, p.1). There are other reasons to collect data. Data also helps people to understand the processes with which they work. Data can also be collected for the purpose of process control. Numerous manufacturing processes use feedback data to adjust an input, such as temperature, in order to keep the output at the desired level. Feedback data from quality control activities can be used to make adjustments that result in more products meeting their requirements (Burrill, Ledolter, p.381). Data can also be used to improve processes with the intent of increasing productivity. ‘Data is nothing, unless interpreted and turned into useful information.’ Data are usually......

To explore the reasons and motivation identified by qualified nurses for working within the surgical area. Background. Little is known about the career decisions qualified nurses make, although it is clear that some areas of practice are more popular than others. This qualitative descriptive study considers one common area, surgery, and explores the motivation for decisions made by Registered Nurses (RNs) to work in this area. Method. A sample of 16 RNs working within surgical areas participated in semistructured interviews, using a thematic interview schedule. Findings were analysed using the framework suggested by Morse and Field. Results. Analysis of findings indicates that all participants actively chose to work within surgery and that this was because of the pace and turnover of surgical work, personal satisfaction at the recovery of patients; the close links between this type of work; and participants’ original aims when first entering nursing and participants’ preference of surgery to other areas of nursing work. Participants actively rejected working in areas where patients were likely to suffer from chronic long-term conditions where recovery was......

Experimental Method Design

...Abstract The objective of this paper is to explore the fundamental circumstances to sustain the validity of prosocial behavior using experimental methods. The focus is on psychological issue of prosocial behavior, and evaluated these concepts using a descriptive method design. In doing so; this paper describes the sample populations, the experimental methods, and provide a speculation on the expectation of the outcomes of prosocial behavior in these scenarios. In addition, this paper further discusses the established sequence of necessary conditions to support the validity of prosocial behavior in reference to bystander effect. In conclusion, relating the conditions of the survey for reliability and to evaluate whether or not the methods discussed measures and are confirmed through the internal consistency, test-retest reliability, and support an inter-source agreement. Experimental Method Design The bystander effect is a psychological episode in social psychology that connects with incidents when individuals refuse to assist in an emergency situation when others are nearby. In the past, the probability of help as been believed to be involving oppositely affected variables comparable to the number of bystanders, for instance, the more bystanders, the least likely anyone will help. John M. Darley was the first social psychologist to make obvious the bystander effect. In this experience, an emergency situation is thespian, and the participants are alone...
