¶ … Searching
All databases comprise of records described by search engines used in searching these records or data. While search engines appear to differ, the underlying principles of database searching and strategies are common. The first principle argues that before an individual begins to search for any information, he/she should develop a search strategy. This involves brainstorming about the keyword to be used (Ullman, 2011). It is imperative to take into account possible synonyms such as automobile and car, alternative spelling like labor and labor, organization and organization, and plurals. The second principle applies to people searching for older materials. This principle requires researchers to consider changes in terminologies. This could be because of developing complex vocabularies and modifying them into appropriate languages.
The Boolean principle stems from the George Boole who focused in writing about a principle designed to elicit better search results through the formulation of precise queries. This principle is sometimes known as the calculus of thought. The Boolean principle is rooted on this thought and its operators: NOT, AND, and/or applied in linking phrases to obtain precise searches (Ullman, 2011). The Boolean principle is helps researchers to define and focus their searches. The three aspects of this principle are essential in the narrowing and broadening search results. It is an important concept to learn because its three aspects are integral in effectively...
This principle limits a search by demanding that all terms after and before "AND" must be present in the article for it to be retrieved in the search process. For example, a researcher must type children AND eating disorder to generate results that refer to both children and eating disorder (Ullman, 2011).
"OR" helps to widen a search as every hit contains either term. This principle can expand a search by demanding that the search phrases after and before it must appear within the article for it to be retrieved during the search process (Ullman, 2011). For instance, a researcher could type adrenaline OR epinephrine to generate results referring to adrenaline and epinephrine. This principle is useful when a researcher can describe a term in multiple ways and will obtain findings that contain both terms.
"NOT" is used to narrow a search through excluding data containing the specified words. The Boolean principle NOT additionally limits a search by demanding that the search term after NOT should not be present within the article in the process of searching, for instance, obesity NOT hypertension.
The "Thesaurus Principle" states that when a researcher encounters a database including a thesaurus, the researcher must make use of it. Running a search on a thesaurus of a database could help select terms, which are indexed…

Database Presentation The objective of this study is to present a new database to be implemented in the clinical setting to increase quality and safety of patient care. The database at focus in this work in writing is that of the Targeted Therapy Database (TTD) in a Cancer unit in a hospital. The work of Mocellin, et al. (2010) relates that the "efficacy of current anticancer treatments is far from satisfactory and

Databases and Data Management Every day, nurses health care practitioners challenged managing large quantities data information. Unless data information translated knowledge, meaningful . Databases data management techniques, designed effectively, present health care organizations Epic database is designed for large health care organizations. The database captures data related to patient care in a health care organization. The database facilitates patient registration, treatment scheduling, lab test results, radiology information, and billing. The database is
Database Development The objective of this study is to recommend three specific tasks that could be performed to improve the quality of datasets using the Software Development Life Cycle (SDLC) methodology and to recommend the actions that could be performed to optimize record selections and to improve database performance from a quantitative data quality assessment. Finally, this work will suggest three maintenance plans and three activities that could be performed in
Work-Related Attitudes: Prejudice, Job Satisfaction, And Organizational Commitment Area of the Study: A worker's attitude heavily impacts his behavior and his performance in any organization. A positive attitude results in an increase in overall productivity for him and the organization because of the feeling of optimism, pride and job satisfaction. A negative attitude will result in negative behaviors which will then lead to job switching or lack of productivity. There are many
Database marketing, sales force automation and virtual reality are three of the newest trends in technology to impact the way company's market to their customers. All three technologies offer specific advantages and disadvantages for their use. The appropriate use of the technology must be based solidly on the type of product, costs incurred, and the nature of relationship with clients. When used in a judicious way, all three technologies can
