1. Define CRUD. gives a web application its full functionality for users with 4 interaction modes: create, read, update, delete.
2. There are seven verb + path combinations that are necessary in a basic Sinatra app in order to provide full CRUD functionality. List each of the seven combinations, and explain what each is for. '/tasks' + get: shows all entries '/tasks/:id' + get: shows specific entry by id '/tasks/new' + get: shows/renders form to enter new information '/tasks' + post: creates new entry and redirects to 'tasks/:id' '/tasks/:id/edit' + get: shows entry form with entered information to update information '/tasks/:id' + put: overrides existing entry with new information and redirects to '/tasks/:id' '/tasks/:id + delete: deletes specific entry by id

## Models, Databases, Relationships in Rails

#### What is the difference between a primary key and a foreign key? Where would we find a primary key? What would it be called by default? Where would we find a foreign key? What is the naming convention for a foreign key?

Primary key is unique identifier of entries in table (row). In a one to many relationship the primary key of the one becomes foreign key of many - table. Default name of primary key is id. As the foreign key it is called "tablename_id".

#### Write down one example of:
* a `one-to-one `relationship. One person owns one bycicle, shared attributes: bike-rack, bike-pump.
* a `one-to-many relationship`. One person has many clothes.
* a `many-to-many relationship`. Rentals-to-Customers

My colde here

• Responder #1: (here) - The definition of a class in this case probably makes sense but I don't know enough about it yet. Interesting approach using map and reduce in one function. I don't like that the inputs are treated differently, one with split and one with atChar, makes it harder to read for me but makes it short and concise. Interesting use of =>. This synthax is new to me, might have to do with using functions within a class. Curious to find out more about it.

• Responder #2: (here) - This approach is very similar to my first attempt to make the test pass. Can be refactored to break out parts in seperate functions. What I like about it is the use of charAt(index). I wasn't aware of this method and used split instead. This makes it shorter and easier to read.

• Responder #3:

Goals/More Checkins

• Optional additional checkins to accomodate for different needs:
  • some might like/want more guidance and push to try out new things, need to reevaluate
  • some need more flexibility to work on their own/ also use more time for job search
• Optional in person project evaluation (you are already doing that, right?)
  • To gage how the output of scale up would range in the job world
  • Did I deliver enough for two weeks on the job?
  • Is the quality of my work/code base comparable? What do I need to improve?
• How was my workflow/process?
