NR 439 COMPLETE WEEKLY NURSING ASSIGNMENTS Week 3 Research Database Latest

PURPOSE

You are to locate and document research databases that relate to a significant clinical nursing issue of your choice. The research databases may be labeled as such, or may be collections of research studies and reports. You are not looking for research or articles; you are looking for new databases.

COURSE OUTCOMES

This assignment enables the student to meet the following course outcome:

CO 1: Examine the sources of evidence that contribute to professional nursing practice. (PO #7)

DUE DATE: You are to identify a total of five research databases (or collections of research-based evidence) that are relevant to a significant clinical nursing issue that is important to you. Submit the descriptions using the form provided in Course Resources to the Week 3 Dropbox by 11:59 p.m. Sunday (MT).

POINTS The assignment is worth a total of 175 points. Please see the grading rubric for details.

 

REQUIREMENTS

1. Choose a topic of interest to you that is a significant clinical nursing issue. Please note that the databases you identify could be useful sources of information for your Capstone project in NR451, so choose your topic thoughtfully.

2. Download the NR439_Research_Database_Form from Course Resources and type information about each database directly onto the form. Your paper does NOT need to follow APA formatting; however, you are expected to use correct grammar, spelling, syntax, and write in complete sentences.

3. Save the file by clicking Save as and adding your last name, e.g., NR439_Research Database_Smith.docx.

4. Describe your topic of interest. This is worth 15 points.

5. Locate a total of five research databases related to your topic. Each research database description is worth 30 points. You may search for these in various locations, e.g., the Internet or the CCN Library. You may NOT choose the databases that are already familiar to you –MEDLINE, PUBMED (which also indexes MEDLINE), GOOGLE SCHOLAR, and CINAHL. Instead, you are expected to expand your knowledge of evidence-based sources. Places to help you begin include your textbook, which lists databases and websites that report research. The Chamberlain online library (http://library.chamberlain.edu) gives you access to several databases and provide tutorials for searching. Government sites such as those at the National Institutes of Health offer collections of research on a variety of subjects. The key to choosing the databases is that each contains research-based evidence that also pertains to your topic of interest. Again you are looking for new databases to use in the future and not articles related to your nursing clinical issue.

6. Review each database to gather information to create a description for the assignment. Each description must:

a. identify the title of the research database;

b. describe the location of the research database in a way that a reader could find it. This should be the URL. This URL should take you to the home page of the database.

c. name owner or publisher of the source;

d. describe the research database. This must be in your own words and not copied and pasted from the original source. Include the purpose of the database and the subject matter it covers. This may be two to three sentences; and

e. explain how the research found in the database relates to your topic of interest. This may be a two or three sentences.

7. Submit to the Research Database basket in the Dropbox by 11:59 p.m. MT Sunday at the end of Week 3. Please post question about this paper in the Q & A Forum.

EXAMPLE

The following is an example of a description for JBI:

Title of Database: Joanna Briggs Institute for Evidence-Based Nursing and Midwifery

Location of Database (URL): www.joannabriggs.edu.au

Owner or publisher of Database: Joanna Briggs Institute for Evidence-Based Nursing and Midwifery (JBI)

Describe (in your own words) the research database or collection of research including the purpose and the subject matter it covers:

The Joanna Briggs Institute is an international not-for-profit Research and Development Organization that provides evidence-based resources for healthcare professionals in nursing, midwifery, medicine, and allied health. Those with membership are able to obtain evidence-based practice information from systematic reviews, evaluation reports, electronic journals, best-practice information, and consumer healthcare information.

Explain how the source relates to your topic of interest:

JBI is relevant to my topic of interest because it provides reports, systematic reviews, and journal articles, and best-practice information on current issues in healthcare. Hospital readmissions are a major issue in healthcare. The database had several resources addressing the problem of hospital readmissions and identifying strategies for improvement?

ADDITIONAL INFORMATION 

Researching databases

Introduction

If you’re new to database administration, it can be confusing to choose the right database for your needs. There are many different types of databases available today: relational, non-relational, and semi-structured. Understanding how each type works and what makes it better than another will help you make an informed decision when choosing which type of database is right for your project.

Design

Designing a database is different from designing an application. The goal of a database is to provide valuable information about your subject, while the goal of an application is to do something with this information (such as create a website or mobile app). In fact, if you’re thinking about building an app that uses data from your database, your first step should be to decide whether or not it would be better to build it as part of one unified system rather than two separate ones (one for each platform).

A design process involves several stages: defining requirements; gathering data; organizing data into tables; creating relationships between tables; adding indexes and constraints on columns—and then iterating through these steps until all necessary requirements are satisfied. In addition to being creative in nature and involving iteration through multiple iterations over time as well as collaborative work between designers and developers (who often specialize in different areas), designing databases requires careful thought about how each piece fits together within the larger whole so that everything aligns properly when finished!

Purpose

The first step in creating a database is deciding what you want to store. This involves answering questions like:

• What do we want to store?

• How often does it need to be updated?

• What kinds of queries will be run against it?

• How much data will be stored in the database, and how much space does it require on disk or memory (RAM)?

Language

SQL is the most common language for interacting with databases. It’s a declarative language, which means that you tell the database what to do, not how to do it. SQL is also a structured query language (SQL), meaning that each command has its own structure and can be broken down into smaller parts for easier reading and understanding.

SQL lets you access data from tables in your database. You can then use this information in other commands or queries to manipulate different parts of your dataset—like adding new rows or changing existing ones—or simply view them all at once as they are displayed by default when using SQLite3 Manager or MySQL Workbench (note: these tools aren’t included in this course).

Frameworks

Frameworks are pre-built software packages that help you build applications. Frameworks can be used to develop web applications and desktop applications, but they’re most commonly used for front-end development (i.e., the part of your application that people see).

Relational, non-relational, and semi-structured databases

Relational databases are the most popular and widely used type of database. They are organized into tables that contain rows and columns, each row representing a single record in the table. The columns represent attributes (fields) for each record, while the rows represent instances of those attributes.

Non-relational databases can be useful for specific applications because they don’t require joins across multiple tables like relational databases do; instead they store data independently within each column or field. These types of databases include object-oriented databases such as DB2 or Microsoft Access and object-relational mappings (ORM). Semi-structured data includes unstructured text files, XML documents and JSON files–all with unique format requirements that make them difficult to work with using traditional relational techniques

Data modeling and normalization

Normalization is the process of transforming data so that it can be easily used in other applications. It’s important because it helps you avoid problems with data integrity and consistency, which could lead to errors or poor performance.

Normalization consists of two steps: first, you have to group your database tables into categories called domains; then, you create relationships between those domains. These relationships are called joins (or “joins”). For example, if we were working on a project that was going to require us to analyze traffic data from multiple sources (e.g., different countries), the first step would be grouping all of those tables together into one domain called “segments.” Once groups like this have been formed—which makes sense since they’re all related—then we need a way for them all share information about each other without having their own separate databases or files sitting around somewhere out there in cyberspace where no one knows what’s happening as far as access rights go around here at home base camp overnight headquarters here today but tomorrow may be another story altogether maybe not maybe even tonight maybe tomorrow night but still tomorrow sometime soon enough so keep up hope rise above doubt despair fears defeat surrender admit defeat lose faith hope love optimism purpose drive motivation dare dream dare dream big dare reach higher dare reach high beyond limits set by society

Database models versus database instances

When you’re designing a database, you need to consider two different types of objects: database models and database instances. A model is conceptual in nature, while an instance is physical. An instance can be different from another instance—it’s not guaranteed that every row will have exactly the same values or structure (this is called aliasing). Furthermore, each row will exist in only one place at any given time: if you delete one copy of a row from your table, all references to it will still point to zero copies elsewhere in your data store.

Database designers create models; they don’t create instances directly because they are too complex for this purpose. Instead, they work with other people who do so (called database administrators), who create these objects directly when creating databases based on their own needs and constraints (e.g., “the first column must always start with ‘A'”).

Primary keys and alternate keys

The primary key is a field that uniquely identifies each record. It’s the one you want to use when you join two tables, and it must be unique within the same table. For example, if we had a customer database with customers and orders, then each customer would have its own primary key called “customer_id”.

The alternate key is used when joining two tables together in order to maintain integrity between them: if there were two orders from different customers stored together in one place (e.g., in a single row), then this would violate our data integrity requirement by allowing someone else’s information into your own database! You can think of an alternative key as being like the index card on which we write down all our contact information for any given person—it doesn’t matter how many times I’ve met her/him; all that matters is what combination of letters gets assigned each time (i.e., which name).

Foreign keys, inner joins, and outer joins

Foreign keys are used to link tables together. Inner joins and outer joins are two different types of joins, which are useful when you want to retrieve information from two or more tables. An inner join forces rows from one table into the same row in another table, while an outer join only selects rows that match both conditions.

Inner Joins: When you have multiple fields that share a column name, choosing this option will ensure that each value in your foreign key column is included in your query results if it exists in any other field on either side of it (in other words if there’s another record with the same name). For example: If there’s an entry for NameID 1 AND NameID 2 then both names should appear; however if there were entries with both names but only one was associated with an ID then those would be excluded from being returned by this query method since they don’t match up against any other criteria yet exist within our database structure itself.”

You can choose the right database for your needs by evaluating your requirements.

You can choose the right database for your needs by evaluating your requirements. The first step toward this process is identifying what you want to accomplish with a database and how it will be used. Then consider how much storage space and processing power are available on your server, as well as any cost constraints such as budget or licensing fees. Once you have identified these factors, review some common databases that meet those criteria:

• Relational databases use tables stored in files (usually flat files) created using SQL statements that define relationships between rows within tables based on columns in related tables; they’re often used when there’s high volume of data entry into small fields with large numbers of rows per table (e.g., customer records). They work best when all users access the same data at once through shared resources such as network drives or cloud storage systems like Dropbox or OneDrive

Conclusion

The most important thing to remember when choosing your database is that you need to consider the context in which it will be used—what are its requirements? What types of data do you need to store? How much data can it handle? How often will it be updated? These questions will help you determine whether relational databases are right for your project.
