CST363 Learning Journal Week 4

 This weeks learning journal prompts are:

1. Briefly summarize 5 things what you have learned in the course so far.  

2. List at least 3 questions you still have about databases.


1. SQL - Learning how to use SQL was great for me. I had never previously used SQL and I found it to be a very approachable and simple programming language. I learned how to perform queries and build tables to organize data in a manner that was accessible and practical.

   Entity Relationship Diagrams - These diagrams I found to be very useful in the initial build out of a database and helps create a visual representation of entities, their attributes and relationships. The ERD can also be used to generate the code required in SQL to model the ERD.

  Database Design Process - The text and lectures provided some good guidelines on the process to create a database. I learned how to understand the database requirements by speaking with the end users and also the process of analyzing, designing and building out the database.

  Database Design Application Using Java - In parallel to SQL I also learned how to implement the database concepts into a java project. This is a good application as it allows me to take the theoretical knowledge gained about databases and applying it in a codebase.

  Relational Database - I learned what a relational database is and how it is structured. I also learned about the benefits structuring data into a relational database can provide, including abilities to query, insert and delete records.


2. The first question I will be exploring are what other types of databases are out there beyond relational and how can they be applied and utilized.

    The second question is what frameworks or APIs are available to assist in database creation and help to streamline some of the more common database operations.

     The third question I have is what other algorithms exist for querying data, beyond linear and binary searches.

Week 5 Learning Journal

Part One:  Supporting and Commenting on Teammate's Goals I visited the following teammate's blogs and commented on their goals. Juan's Blog Vance's Blog Part Two: Possible Capstone Ideas The three ideas I have for my capstone project are two different mobile apps and one indie game. For the two apps I am thinking of creating something in Swift, the programming language of iOS. The first app is a passion project that involves a list builder for a miniature tabletop game called OnePageRules. It is an independent miniature game ruleset and already has a web version. My app would take that template and adapt it for iOS. The second app would be a simple star wars app that utilizes an online API for Star Wars call SWAPI. This API has a number of entries related to the Star Wars universe in JSON format. My app would connect to this online API, download specific pieces of data and display them in the app.  The third idea would be to create a simple side scroller game. The game ...

Leetcode Practice Reflection 1.Two Sum

LeetCode Practice Reflection - 1. Two Sum Date:   19MAY25 What I Worked on Today: Practiced doing LeetCode Problem 1.Two Sum. What I Learned: - How to use the enumerate() function - How to optimize possible solutions after considering brute force methods - How to declare a new dictionary (key value pair) Code Snippet I Wrote or Studied: class Solution(object): def twoSum(self, nums, target): seen = {} for i, num in enumerate(nums): compliement = target - num if compliment in seen: return [seen[compliment], i] seen[num] = i In My Own Words: This function takes in a list of numbers and will return the index of the two numbers that add up to the provided target value. The way this program works is that it creates a dictionary called "seen". It will then iterate through the list of numbers and use the enumerate function to keep track of the index and the value of the specific item in the provided list. The for loop will calculate the compliment numbe...

CST311 Week 6 Journal

 This week, we developed a deeper understanding of the network control plane and explored routing algorithms such as Dijkstra and Bellman-Ford, focusing on how they determine the most efficient paths for data transfer. We also learned about the SDN control plane, which allows for dynamic network management and routing. In addition to the theory learned this week, we conducted a network lab exploring the use of a basic SDN controller using Mininet and Wireshark. We looked at how Internet Control Message Protocol (ICMP), can be used for network diagnostics, particularly for network troubleshooting with tools like ping and traceroute.
