CST 363 - Week 5

 An index on a database is supposed to speed up the process of a query.  There are instances where using an index can do the opposite of this intended feature.  An index is performed in three steps.  The tree traversal, following the leaf node chain, and retrieving the data in the table.  If blocks (the leaf nodes and the table data) are made too big then every time the index is performed, it will have to research through the entire block making the query take much longer to find the same information.

 The Agile and Plan and Document (Waterfall) processes are very different.  In the Agile process, iterations or sprints are used to complete smaller tasks rapidly whereas the Waterfall process follows a predetermined timeline for deliveries.  The Waterfall process is usually used for very large projects and takes much longer due to each delivery being reliant on the previous one.  Also Waterfall process uses a large chunk of time to rigorously plan everything at the beginning of the process whereas Agile allows for changes throughout the process because of the smaller deliveries each sprint.  This allows for quick and simple testing of each delivery versus the Waterfall process that usually begins to test near the end of the final deliveries because again each delivery relies on resources from the previous.

  How does React compare to other frameworks you have used for front end development?  I have not had much experience with front end development frameworks.  I have had little experience with JavaScript and HTML.  One thing I noticed about React that is helpful is the ability to have HTML embedded directly into JavaScript rather than have numerous HTML files and JavaScript files.  This is useful in maintaining readable code and code that is easily navigated.
