CST363 Module 6

 

  • Compare MongoDB with MySQL.  What are some similarities?  What are some differences?  When would you choose one over the other? 
    • MongoDB and MySQL have some surface level similarities such as both of them being suited for efficiently storing and accessing data sets. Beyond this they both support simple data types such as integers, strings, doubles, etc.
    • Some of the differences they have between each other mainly comes from MongoDB being a NoSQL structure, primarily meaning it doesn't use SQL queries to access data. SQL also stores data relationally in tables with predetermined columns or attributes while MongoDB stores data in the form of 'documents'. These documents have no pre-set size, data-types, etc.. Documents can have different attributes on the fly. This allows MongoDB to handle more non-uniform data sets.
    • At the moment I'm unsure which database I would rather use, it would probably depend on the project. The possibility to have non-uniform data using MongoDB is definitely interesting but I have had much more experience with SQL and its query's as of this moment. Whichever method, relational or document based, is better for any given project is what I would use.

CST489 / 499 Week 16

  For this week, please spend time browsing through your two years of journals and reflect on your overall experience and growth in the program.

I hope to continue to grow as I have these past 2 years and into a position where I can leverage my new skills.

CST462S Module 8

What went well? What would you improve? What was the most impactful part? What challenges did you face? Overall I was able to complete my service hours but with some difficulty in making sure I made my weekly goal, ideally I could have started earlier to allow my site more time to assign me tasks. Our class essay went pretty smoothly throughout the course even though my group and I were dreading completing the assigned section of our essay every week. In terms of challenges for this course it was mainly just scheduling, having 2 classes at the same time with what felt like a standard workload we’ve come to expect from each with our service learning on top. If instead 462S was on it own and our graphics design course was paired up with a different course such as the web design one, then it would have been a much more manageable courseload.  What advice do you have for future SL students? My primary advice for this is to start as early as possible. Having 2 classes worth of work plus...
