This journal will be used for new things I learn and would like to document and share.

CST363 Week 2
During this week we delved into Relational Algebra (a procedural query language, which takes instances of relations as input and yields instances of relations as output. It uses operators to perform queries. An operator can be either unary or binary. They accept relations as their input and yield relations as their output.) and how it relates to SQL (Structured Query Language). We were also introduced to SQL commands and installed a local Oracle database.
