Nair – Week 6

Chapter 7: 

• This chapter was mainly about debugging and how to fix errors when coding. 
• I have done this before my computer science classes, and debugging has become an easier task for me now. 
• I’ve already been taught a lot of the techniques mentioned in the chapter through my professors so I was able to get through this chapter easily.

Chapter 8: 

• This chapter was about manipulating spatial and tabular data and using concepts learned in past chapters for application. 
• I also came across the term cursor – a database technology term for accessing a set of records in a table, and its types( search, insert, update) 
• These functions are essentially used to insert, update, or search things through tables.
• The Cursor  also has other functions like delete and reset. 
• The chapter also talks about working with SQL expressions and text and CSV files. 
• I’m still learning SQL so it took me a while to understand the syntax
• It is also interesting to learn that a lot of these tools that we used for GIS 191 and 192 are made using Python.
