What are the analysis and algorithms? (Complaints)

I have been writing ASP for a long time, so I can't remember when to start writing the first ASP. I just remember that a long time ago there was a bottleneck and I thought I could do anything, but I can't do anything about myself.

System Analysis: ASP is getting bored from the complex dataconn to the dataclose, and the system is getting increasingly difficult to complete. One bad tail system after another makes people have a nightmare at the thought of it. From then on, I began to systematically analyze and explore what object-oriented analysis, models, documents, and the demands for biting texts.CodeI have made many project analysis books, and I have done all the methods in the books. At the beginning, I understood them and made them according to my own ideas. It was useless, annoying, and difficult to implement, that's even worse. The bad system that gave me a nightmare still keeps appearing, as if everything was busy. What books should I go to and try?

AlgorithmI always thought it was C, Pb, VB, etc.ProgramI think ASP is nothing more than dataconn and dataclose. Therefore, the code is smelly, long, and messy. Right ("00" & Day (now), 2) from the beginning to aryrnd (ubound-y) * RND) = aryrnd (ubound-y) In this blog) (See generating random numbers that are not repeated.) When I saw these exquisite codes, I also found that I was just a poor code migrant worker from start to end, how can I learn this?

Recently, I was a bit depressed when writing code. I complained.
