- [[TSQL]]
- Databases can live in a single `.db` file
- queries have to end with a `;`
- The syntax is similar to other SQL's but it of course has it differences and functionalities that it lacks
- Cant seem to find a way to do a string split cross apply with SQLite to take a single column with a string of values comma separated to split them then cross apply them to list and then filter/aggregate them.
- This is making me rely more of more tables in the relational model v.s. robust functions.
### Current ER diagram looking like this:

PERSON ||--o{ TAGS : Has
PERSON }|--o| PROFESSION : "Works As"
PERSON }|--|| CONNECTION : Met

- csv
- clojure
- looked at clojure a little bit but immediately decided against looking into it further since apparently it's meant to run on a JVM or java Virtual Machine.
- I have no intention of looking into Java right now so that was a quick foray into the weird looking syntax of Clojure. maybe something like lisp/elisp for emacs will be more interesting and applicable for me.
- markdown markdown hyperlinks when separated by declaration and definition, they can be re-used!
```markdown

[but I can also re-use the link here!][1]
And this will work all throughout a markdown document
