Week 1 – CST – 363 Introduction to Database Systems

1.      Relational database tables and spreadsheets look similar with both having rows and columns. What are some important differences between the two?

Some important differences between database tables and spreadsheets are the way data is formatted and how data is stored. In a spreadsheet, every cell can store any type of data like a date, integer, or string. These data types can also have their unique format. In a database, each cell must contain only one data type helping to prevent data mismatch mistakes. In a spreadsheet, the data is stored in each cell. In a database, the data is stored in a row made up of columns.

2.      Installing and configurating a database and learning how to use it is more complicated than just reading and writing data to a file. What are some important reasons that make a database a useful investment of time?

Learning how to install and configure a database as well as learning how to use it is an important investment of time because most businesses today use databases to store and manage their data. Modern databases contain enormous amounts of data and support thousands of simultaneous users. Databases systems ensure that data is secure, internally consistent, and available at all times.

3.      What do you want to learn in this course that you think will be useful in your future career?

In this course, I want to build a good foundation for managing databases. In my future career as a software developer, this will be useful because all software has a lot of data. All this data is managed using databases. Learning how to use SQL will also be extremely important because SQL is the most popular language for adding, accessing, and managing databases.

  Week 2- CST-300 Module 2 OLI – Module 2 This week’s module focused on collective intelligence, reading the mind in the eyes, behavior of good teams, and why team skills will help after graduation. Collective intelligence illustrated how teams that have better collaboration skills were more successful. Meaning that everyone participated and contributed to complete the task or project. Some key features of successful teams were equal participation, higher number of women, and social sensitivity. I enjoyed the reading the mind in the eyes activity. It is difficult to tell a person’s emotions by examining just their eyes and not the entire face or body language. I scored about average. I will continue to participate and share my thoughts and ideas on topics being discussed in my team. Behaviors of good teams was a research article done at google looking for the perfect team. They found that teams promote better job satisfaction, better problem solutions and faster innovation.

Here we learned about work styles Get it Right – Task oriented, Get it Done – Task oriented, Get Along – people oriented, and Get Appreciation – People oriented.
