成為後端工程師一年後，這一年寫了數不完的CRUD，用了原生SQL語法和ORM，發現自己對資料庫還是矇矇懂懂，每天都在操作資料，卻覺得資料庫這東西既熟悉又陌生，於是找了Fundamentals of Database Engineering這門課，目標是更有系統性得了解資料庫的原理，我把自己上這堂課的筆記都寫下來，裡面包含自己實際跟著課程操作資料的過程（資料內容未必跟課程一模一樣，大部分是依照課程內容再自己做一些變化），以及對於比較模糊的地方，再去找資料來看的筆記，若有錯誤，歡迎留言指教
（點選標題就能連結到筆記內容，標題是我自定的，未必跟課程標題一樣）

What’s recursion? A function calls itself and runs again. An easy example below: func rc() { rc() } Every recursive function needs to have a base case or a stopping point. If the stop case doesn’t exist, the recursive function will keep running ...
Reverse A String: 把任意input的string倒敘排列 JavaScript: 解法一：先把input string轉換成array，組合後再轉回string，最後return Time Complexity: O(n) for loop會iterate整個string → O(n) join會iterate整個array → O(n) Space Complexity: O(n) push把資料一個一個放入result array → O(1) join會建立新的strin...

Data Structure: a collection of values Algorithms: processes to manipulate these collections of values What is a Data Structure? A data structure is like a container for organizing related data. The key is knowing how to organize the data in a suitab...
Why learn to use Big O? Use Big O to measure how and why one data structure is better than others. Why do we use an array rather than an object in some cases? Each data structure has pros and cons. Big O is used to describe how efficiently the code r...
