week 18 cst363 week 2

 This week we reviewed sql functions and referential integrity.

functions are scalar or aggregates, like CONCAT or GROUP BY.

referential integrity refers to different kinds of constraints we can place on tables.

primary keys must be unique and not null

unique keys can be null

foreign keys relate tables by column references

we can place other constraints on our data like enforcing NOT NULL and enforcing values within certain ranges.

Part 1 Top 3 things I'm good at:  keeping to a schedule  extracting meaning and main ideas when reading writing from an outline Top 3 things that need work: removing distractions from my study space taking notes consistently going back to recite what I've read Part 2 Part 3 Projects are efforts to complete some objective that is aligned with a business strategy in a way that is bound by time, cope, and cost. The project manager is the CEO of a project, responsible for its execution. A work breakdown structure is a hierarchical breakdown of all deliverables in a project. It's organized from the entire project scope to major deliverables, and then recursively any sub-deliverables until there is an exhaustive list. The purpose is to define the full scope of the project and support creating a schedule and budget.

Both presentations communicated the problem of ethical issues of AI at war clearly. 3. how is the quality of the research? No references cited.

I am still driving hard to complete an undergraduate degree so I have the option of pursuing further education. I'm interested in an MBA to refine my business leadership skills. My second educational goal is to be accepted to and start an MBA program in the year after completing my BS. Part 2 I want to return to organizational leadership but with a new set of skills that I learn from reaching my educational goals. I want to build and maintain a level of credibility in leading larger organizations than I have in the past, to end my career on a high note.  Part 3 I feel pretty good about the test.

I'm pretty confident in being able to prepare well, but a...
