1:55:46 - For anyone following along. The video games database from Kaggle has been updated, so column order will be different. Also notice: Professor Trummer is using NULL AS 'N/A', You might encounter an error where you cannot copy the CSV data into Postgres because of empty delimiters (,,,,), I suggest cleaning up the CSV file by issuing: sed -i -e 's/N\/A//g' yourfile.csv and using COPY yourtable FROM '/var/lib/postgresql/data/yourfile.csv' DELIMITER ',' NULL AS '' CSV HEADER; which should result in success.

[@oceanview3165]

If I knew what I know now after spending thousands of dollars on a CS degree, I would start teaching myself front end development and data base back in freshman year and gradually learn data structure and algorithms along the way. Because now that I am a senior with no knowledge of web development just except copying and pasting of react code to get the project done, I feel pretty dumb compared to other self taught programmers who are actually familiar with different frameworks.

[@alb12345672]

CS degrees teach fundamentals. I graduated with an EE/CS degree in 1995. The stuff today is very similar (Maybe a step down, we used C++, now they use Python or Java). No school is going to teach you react. Same way back then they wouldn't teach you Visual Basic or even MFC. They are teaching you academic CS, which gives you the power to quickly pick things up. But we did have an SQL course like this (I just jumped around in it, I'm using SQL now for all that time!). I did use FCC to learn React though!

[@amazhobner]

BST type of index improves results by a factor of two, this factor can be increased using tree indexes and hash indexes. B+ Trees Index. Tree Index: Traverse search tree to find interesting leaf. Hash Index: Evaluate Hash functions to find buckets. Where to use Tree Indexes? Can be used if where clause uses equal or not equal predicate. Works if predicate references index key. Tree Indexes store data in root-leaf format. Similar data is stored closed together. Hence useful for both equality and inequality predicate. Hash Indexed store data in key:hash pair, similar value may hence be far apart. Hence useful for only equality predicate. Hash Index Variants: 1) Static Hashing(Bad for dynamic data) SS in folder. 2) Extendible Hashing (Expands with few high-overhead operations) 3) Lnear Hashing (Expands more "smoothly") About Data Storage: Data is stored in some physical hardware. More the memory of that, less is the volatility but so is the query time. Lesser the memory, more the volatility but lesser the query time. Volatility refers to recovery after failure. Data is stored as files, each file is further divided into slots which are further divided into fields. Buffer stores the most frequently possible used data to reduce the query time, it retains count of how many times the data was retrieved and if it goes below say 0 or a specified amount then that data is removed from buffer. Indexes- Refer to SS. Query Processing: Input query is parsed and simplified(Rewriter). Query optimizer generates optimized execution plan. Executing plan(Executor) produces query result. Operators in Query: 6:13:20
