Weekly Reflection

This week, we learned about database programming. This process involves building applications with SQL and general-purpose languages such as Java. Integrating the two presents two main challenges: syntax gaps and paradigm gaps. To overcome these challenges, three techniques can be used, Embedded SQL, Procedural SQL, and application programming interface (API). APIs are the most commonly used database programming technique since they allow the syntax gap to disappear and reduce the paradigm gaps. 

When data programming with Java, the API Java Database Connectivity (JDBC) is used. This API allows the use of Statements that define and execute SQL queries. Values are set via a ResultSet and a next() method. PreparedStatement allows us to use parameters in SQL statements. This practice was put into use for Lab 17, where we used these interfaces to insert and select data from the student table in the Course database. We also implemented these interfaces using a Web App called Spring Server. We completed code that allowed us to use IntelliJ to insert and update data obtained from the Spring Server and apply it to the database in MySQL.

 Part 1: Review of other team's final video projects Final Video Project Review # 1: Otter This World The video project from Otter This World is about Genomics. They describe how genomics is important and what advances we have made in this area. The topic is well-covered, and the presentation is clear. They cover each section described at the beginning of the video and provide various videos that go along with those sections. The quality of the research and video project is well done. They provide definitions and statistics with references. The video has a lot of visuals and could have used some slides with text at the beginning of each section. The information is being provided via audio, and there should be some text to supplement it. Also, the General Public video cuts off at the end with no conclusion. The video is engaging and interesting. They made a nice choice of visuals for each section. Team work is evident as each person had a section they covered. Overall, the video is

Part 1: Support and Comments on Teammates' Goals Victoria's Comment Guillermo's Comment Part 2: Possible Capstone Ideas Some ideas for capstone that I have are in the area of education with a focus on classroom management and video game design.  My first idea is to create a seating chart generator app for teachers to use in their classrooms. As a teacher, creating a seating chart can be a challenge. Whether you have a challenging class or are just looking to mix seats up, this app will help create the perfect seating chart. The app will give the teacher a variety of options to create a seating chart: individual, partner, or grouping (3 or more). The teacher can create a seating chart or groupings based on current grade in class, on an assignment, IEP requirements, or behavioral issues.  My second idea is to create a school environment application or website. With technology in the classroom becoming more and more popular, students are having to manage their own apps, homewo
