CST 363 Week 7

  • Compare MongoDB with MySQL. 

MongoDB is a Non relational database and MySQL is a relational database.


  • What are some similarities? 

MongoDB and MySQL allow for database administrators to store and update data. Both languages are capable in their own ways of creating entities with attributes. They are also capable of querying and filtering data.


  • What are some differences? 

The way data is stored varies between both. In MongoDB, data is stored as binary encoded JSON documents. MongoDB allows for these documents to store nested documents, which allows multiple values to be stored under one field type. In MySQL, data is stored in tables with columns as rows. This database structure only allows for one value to be stored per table cell. Additionally, another difference between MongoDB and MySQL is the syntax of their query languages.


  • When would you choose one over the other? 

At the moment I have a better understanding of SQL than the MongoDB query language. Because of this I prefer MySQL over MongoDB. In MySQL I know how to join tables and perform other database operations whereas with MongoDB, I am not sure how to do these things. This aside, I think MySQL transactions better ensure ACID properties in large databases than MongoDB. On the other hand, MongoDB may be more suitable when objects stored in the database do not share identical fields or when a database schema can not be strict

Part 1: Review and Reflect Learning Strategy     After reading "Effective Study Skills" by Dr. Kizlik, I learned I do a few things well in school as well as a few things not so well. First thing I think I do well is schedule my time. I believe I set my schedule well at the beginning of the week when assignments are posted. I will prioritize my schedule based off of the due date and difficulty of the assignment. Because of this, I can usually finish assignments ahead of time, and I can use extra time to study if needed. Another area I feel like I do well in is outlining my essays. I like to outline my papers before I write even if it is not required. I believe I can keep my ideas organized better, and I am able to pre-write my papers more effectively because of the outline. Lastly, when I study, I effectively use "reciting" to help me retain information. I think this small step has a significant impact on how effective my study time is. This is something I have done ...

CST 300 week 4

Part 1:      One of my main goals throughout this program is to understand the big picture when it comes to software development.  As of now, I don't have any experience outside of java and object oriented programming. I understand how to code and create logic, but I have yet to apply this knowledge to a project that would introduce me to areas of work that I should know as a software developer. I also hope to learn more of about engineering methodologies through some the group projects along the way. My previous classes for computer science have not required me to work with anybody else, so I hope to get better at this. Another area of concern for me right now is that I am only proficient in Java at the moment. As I take classes that require me to learn new languages, I am going to take additional time study these languages and strive to become proficient in them. Right now, I want to learn Python and C the most. Outside of school, I am working on a data structures ...

CST 300 week 3

Part 1:  https://www.academictips.org/acad/index.html      Something that I struggle with in school is note taking. One of the tips mentioned in the article that I thought was the most helpful is preparing for lectures. If students know what a lecture is about, they can prepare questions for their professor ahead of time. I think the most important benefit of this practice is that you can focus on taking notes on the material that you struggle with. This style of note taking would lead to less time spent writing and more time spent listening to the lecture. Additionally, this could help a student keep up in a lecture in a class where the professor teaches quickly. I feel like this kind of strategy has helped me get through harder classes in the past, and this is something I need to incorporate in routine more often. Part 2: What I learned this week      While working on the scenario based ethics assignment, I had the opportunity to review Kantian Deont...
