太郁闷了 每天都是重复的工作 增删改查
You're asking the wrong question, my friend.
Don't blame the CRUD for all the bullshit that is often associated with it.
(Reminder: CRUD stands for Create Retrieve Update Delete, and is the underlying philosophy for the database applications that run the world we live in, the 90% of the iceberg that most hackers never see or even think about.)
I've been doing CRUD for 33 years and it's been an incredible ride. I credit my CRUD work for putting me in the right hand 5% of that bell curve, ahead of the rest of my fellow hackers who have built so little of substance.
Sure, I've built apps that move people and things to the right place, and also have done a lot of "reports here, manage documents here, upgrade calender software here", but what job doesn't have some crap work go to along with the gravy? I've never seen any good job without it's share of maintenance, refactoring, testing, process, and meetings with drones.
I've also build software that generates other software, invented new frameworks, and devised algorithms that dramatically improved the way we make and build and move the stuff that's probably in your cubicle right now. I've taken cool academic theory from my pure mathematical background to build software that has blown away the posers everywhere around me. And you know what? You do that just once, and every champion in the enterprise runs to you with their giant budgets to solve their CRUD problem du jour with your "genius".
Believe me, you don't have to work at "Intel, Google, Apple, or NASA" to "change the world". You're just as likely to be a cog in the wheel at those places as anywhere else.
You can change the world from where ever you're at, and in fact, if you're working on a CRUD app, I think you're actually in a better position to do it. You just have to ask a better question.
如果增删改把效率和性能考虑进行，是有很多内容可以学的。建议你还是从基础算法入手。CRUD是这个世界上绝大数书系统都干的事情，这个不是你的错
你做的东西已经很核心了，下一步就是如何做好！
想做好不容易的，想想如果上千，上万，上十万，上百万人同时在线CRUD用你
的系统，你的还不崩溃就很不错了！
