Relational database tables and spreadsheets look similar with both having rows and columns.  What are some important differences between the two? One important difference is that a relational database focuses on concurrency. The data that is presented to the user is always the most up to date representation of the data. If one user makes a change that change is reflected in the database and is kept current across all users. A relational database can also incorporate security an permissions that allow certain users different levels of access.  Installing and configuration a database and learning how to use it is more complicated that just reading and writing data to a file.  What are some important reasons that makes a database a useful investment of time?  I think databases are a useful investment of time because many of the applications we use or will build for the future will rely on organized data that can be accessed by users in appropriate and meaningful ways.

I was unable to implement all of the required functionality and get the app working properly. I think if I were to go back and try to rewrite the program I would do a better job at it, partly because I have learned a lot more about Java programing through this course and also because I am more familiar with how Jotto is supposed to function. Before the Jotto assignment I had actually not heard of the Wordle game upon which it is based. I have since been pretty consistent with playing the Wordle game daily and it is quite entertaining. I think this would help me because playing Wordle has given me a clearer idea of what the Jotto assignment was trying to achieve. This class has helped me improve greatly in my Java programming and I learned many things. Two victories that I am proud of is how to build abstract classes and how to build android apps. The LDPM project was o
