DNP 805 Select a defined patient population and list elements that you think will be valuable in a database

Select a defined patient population and list elements that you think will be valuable in a database. What elements are required and why? What elements are optional and why?

“What do you see as the most important elements of databases?”:

Tables, records and fields must be connected. There should be the ability to filter access to information more rapidly to produce results in a timely manner. Data is usually accessed with queries or business intelligence (BI) tools. It’s important for any database to rapidly respond with deduped data.
The ability to support a broad variety of data so that it can be aggregated, analyzed, and reports generated. Each database is different with regards to aggregation and integration. The ability to support a lot of different uses since people are finding new

ways to use data. Ability to store data in a lot of different forms before and after normalization (data preparation). Summations are used for reporting purposes providing another view of data whether it’s structured, unstructured, or semi-structured. Data quality is also important—sensors provide a lot of readings and you need to remove or highlight the exceptions so you don’t need to store all of the data collected by the sensor.
Two types: transactional used by banks, ATMs, and deposit accounts; and, analytical used for asking questions, learning more about the business, and making predictions. Each database is well built to answer a particular set of questions. People used to buy Oracle and build what they needed. Now, there are 30 to 40 different databases each with a specific purpose and use case.
Today we need to think about the original use and then the secondary use of the data. Shift toward in-memory databases. The right database depends on the use case—may need to keep up with speed in a memory-centric database. The use case determines the optimal database. We’re shifting to Hadoop for data mining to scale and web-scale analytics. Databases have bifurcated into what’s most relevant for the use case—“the consumerization of databases.” We’re no longer one size fits all. Every database is created for a particular use case. We’ve moved from transactional to task-driven databases. Read and write quickly for availability and replication.

Performance – ability to process more data, more quickly. There are new ways to deal with data with commodity hardware. We used to need mainframes and microprocessors. Now, you can achieve high performance with low-end hardware pulling them into a cluster (i.e. Cloud). This has led to high performance analytics with low-end hardware. The Cloud is an accelerator for the digital enterprise.

It’s established a new genre of software—SQL to NoSQL. There’s been a renaissance of SQL. Three properties of distributed systems: consistency, availability, and tolerate partitions—you can only have two. It used to be that you couldn’t scale SQL over time. Now, stored data can become consistent data over time. Amazon started this with consistency being promoted right into the distribution center.
It’s more important to understand when selecting—know what the requirements of the data are when selecting a solution. Do what’s on the label and understand what’s on the label. A lot of databases can do one thing very well but not other things that traditional databases would not do. Databases can store a lot more data without semantic data. It depends on what you’re doing with the data. Inside of SQL, have that on top of a lot of technologies with different models like Hadoop. Query languages—at what point do you say a query language is right for one type of data and not another. 1. Transactional model. 2. Data model. 3. Query language.
Primarily with an operation data store—the stuff behind the application. Mobile will have log-in, database with email address, password, and account information. Lyft would track user profiles and rides. Evernote would track notes and other services. Stores for data you want to put away. Deal with operational data stores. Ten years ago you’d have SQL with ANSI and standard queries with SQL. There’s been a renaissance in databases. MongoDB is an operational database.
A database is for storing data in some form of durability to maintain asset properties and the ability to access it. Optimization can differ between the network, memory, and persistence based on the need. Improve usability for the programmer. It’s hard to build a database so that it’s easily usable. Newer databases like Mongo and Couch solve the scale and ease of use, but aren’t as focused on integrity and consistency. You trade speed to scale for other qualities. NoSQL is good for doing front-end work. Security is always an issue when data is involved because data is like money—the bloodstream of the system. You can’t protect the data without protecting the logic around it.
There are many database technologies that serve different needs. Common benefits include centralizing data and standardizing how it is accessed, making it easier and cheaper to manage and use the same data for different purposes. This is often referred to as a “single source of truth.”
Data must remain highly available since every minute of downtime can be prohibitively expensive. If you’re serving thousands to hundreds of thousands of operations per second, the cost of a minute of downtime could easily run into several hundreds of thousands of dollars. There are six features critical to ensuring high availability and safeguard against every type of failure or outage event: 1) in-memory replication; 2) multi-rack/zone/datacenter replication; 3) instant auto-failover; 4) AOF data persistence; 5) backup; and 6) multi-region/cloud replication. These features protect your data from process failures, node failures, multi-node failures, rack/zone/datacenter failures, network split events, and complete region or cloud failures.
It depends on the context—low latency versus high access.

Lopes Write Policy

For assignments that need to be submitted to Lopes Write, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me.

Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes.

Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own?

Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score.

Late Policy

The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies.

Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances.

If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect.

I do not accept assignments that are two or more weeks late unless we have worked out an extension.

As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading.

Communication

Communication is so very important. There are multiple ways to communicate with me:

Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class.

Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.

Important information for writing discussion questions and participation

Welcome to class

Hello class and welcome to the class and I will be your instructor for this course. This is a -week course and requires a lot of time commitment, organization, and a high level of dedication. Please use the class syllabus to guide you through all the assignments required for the course. I have also attached the classroom policies to this announcement to know your expectations for this course. Please review this document carefully and ask me any questions if you do. You could email me at any time or send me a message via the “message” icon in halo if you need to contact me. I check my email regularly, so you should get a response within 24 hours. If you have not heard from me within 24 hours and need to contact me urgently, please send a follow up text to

I strongly encourage that you do not wait until the very last minute to complete your assignments. Your assignments in weeks 4 and 5 require early planning as you would need to present a teaching plan and interview a community health provider. I advise you look at the requirements for these assignments at the beginning of the course and plan accordingly. I have posted the YouTube link that explains all the class assignments in detail. It is required that you watch this 32-minute video as the assignments from week 3 through 5 require that you follow the instructions to the letter to succeed. Failure to complete these assignments according to instructions might lead to a zero. After watching the video, please schedule a one-on-one with me to discuss your topic for your project by the second week of class. Use this link to schedule a 15-minute session. Please, call me at the time of your appointment on my number. Please note that I will NOT call you.

Please, be advised I do NOT accept any assignments by email. If you are having technical issues with uploading an assignment, contact the technical department and inform me of the issue. If you have any issues that would prevent you from getting your assignments to me by the deadline, please inform me to request a possible extension. Note that working fulltime or overtime is no excuse for late assignments. There is a 5%-point deduction for every day your assignment is late. This only applies to approved extensions. Late assignments will not be accepted.

If you think you would be needing accommodations due to any reasons, please contact the appropriate department to request accommodations.

Plagiarism is highly prohibited. Please ensure you are citing your sources correctly using APA 7th edition. All assignments including discussion posts should be formatted in APA with the appropriate spacing, font, margin, and indents. Any papers not well formatted would be returned back to you, hence, I advise you review APA formatting style. I have attached a sample paper in APA format and will also post sample discussion responses in subsequent announcements.

Your initial discussion post should be a minimum of 200 words and response posts should be a minimum of 150 words. Be advised that I grade based on quality and not necessarily the number of words you post. A minimum of TWO references should be used for your initial post. For your response post, you do not need references as personal experiences would count as response posts. If you however cite anything from the literature for your response post, it is required that you cite your reference. You should include a minimum of THREE references for papers in this course. Please note that references should be no more than 5 years old except recommended as a resource for the class. Furthermore, for each discussion board question, you need ONE initial substantive response and TWO substantive responses to either your classmates or your instructor for a total of THREE responses. There are TWO discussion questions each week, hence, you need a total minimum of SIX discussion posts for each week. I usually post a discussion question each week. You could also respond to these as it would count towards your required SIX discussion posts for the week.

I understand this is a lot of information to cover in 5 weeks, however, the Bible says in Philippians 4:13 that we can do all things through Christ that strengthens us. Even in times like this, we are encouraged by God’s word that we have that ability in us to succeed with His strength. I pray that each and every one of you receives strength for this course and life generally as we navigate through this pandemic that is shaking our world today. Relax and enjoy the course!
