Anyone to explain this ACL schema for me - schema

It is joomla schema actually but this really drives me banana as I cannot understand it. Please guys help me interpret the whole thing. I can only understand the jos_users and little part of session. I cannot get what other tables do.
Here is image!

Joomla 1.5 ACL uses the open-source GACL library. You can find more information from these links.

How to start with a DBMS project

We are supposed to make a web-based project using postgres. The topic is library management system, where on a website a user can search whether a book is available in the library, if it is present then where, and so on.
The problem is just that I don't know anything about web development. I do have a pretty good knowledge of sql, but I'm confused a bit in that too, because I don't know if I'll just have to run the queries in my laptop in postgres and link if it "somehow" to the website, or will I have to upload my data on some server (for eg., firebase in case Android development) to be used in my website.
So briefly, I've just two questions:-
How should I start, because I have no idea where to begin with(I do have all the data needed btw)?
About postgres, will the queries run on my laptop or some server?
Please help me with this. Some online resources for the same are way more than just welcome, because I was unable to find any. Thank you!
First of all, you'd take a look at some design pattern in order to learn some theory on how to make (web) apps in the right way. You can visit Martin Fowler's web site and read them.
Once studied, you'd follow my advice. If you've got Java expetise, I'd start by learning Spring Boot, which has every piece you need to achieve your goal. This project follows lot's of design patterns (MVC, Repository, DAO, AOP, IoC/DI...) and lets you follow others (DTO). Anyway, choose the right template engine (I like Thymeleaf) or any other framework (Angular 2...).
Hope it helps.
welcome to development world. When starting out it seems very confusing but it is not that much.
Start slow, there are many tutorials across which helps.. just do a bit of google.
To answer your question :
How should I start, because I have no idea where to begin with(I do have all the data needed btw)?
-- Google simple website with postgres db. For that you will require the database to be installed and a webserver on your machine. All of which will be used when you host the website
About postgres, will the queries run on my laptop or some server?
-- It will run on where you have installed the database..
hope this helps :)

Program that can extract something from a website

I`m sorry if this is the not right place to ask. If not please delete this.
I`m looking for someone that can help me with a very simple program that can do this:
Login into accounts on an website and extract there a number from every account and and save the details ( account number - the number that must be saved ) on an txt file.
I need this for my job. This program will save me a`lot of time. this is the purpose.
If anybody can help me please let me know. thank you very much.
Fortunately for you, there is ample tooling available.
I will provide you some insight into related tools in the Python ecosystem, since that is what I am most familiar with and also an easy languages for beginners to work with.
If what you are extracting/scraping is relatively simple and doesn't require complex UI interaction with website elements, I would recommend requests Sessions to retain cookies and additional information for use in a series of authenticated requests, and bs4 to parse document trees in order to extract the data you are interested in.
For more complex interaction, you will need to look towards browser automation and possibly more advanced scraping frameworks. Hopefully I've given you enough keywords to go far in Google.
Of course, you'll need to first learn the basics of programming and how web data is structured if you want to write scripts like this. That is left to you to learn and absorb.

Amazon search bar api Product advertising

I am trying to place amazon search bar for books category in my website, where user searches for a book and is redirected to amazon website. My URL should be tagged with my associate ID so that i can earn some money.
The problem is i am unable to find any procedure to create such search bar. I have browsed through Product advertising API section, but it is very confusing.
I want exactly like this: http://amasearchbar.com/demo-blog/
Can someone help me how to make such autocomplete search bar, or provide me directly the code for it.
Any help is appreciated.
Amazon isn't likely to give instructions for how to create something like that - but they do give you the tools necessary to figure it out yourself if you're willing to learn their API.
Without more information, it's hard for anyone here to "help" you either.
That link you gave is to a WP plugin. Are you using WP? If so, your easiest bet is to buy the plugin and use that (I am not endorsing that plugin specifically, I have no experience with it).
If you give more specifics on what language you're wanting to use to create the search bar and its interaction with the API, and specific problems you run into while working on it, this community will be much more likely to help you. Questions to point you to a free source for the finished code of your project are not likely to get very far though.
Based on your previous questions, it seems likely that you are using Wordpress. If that's the case, and you don't know how to write the scripts to interact with the API then the easiest answer to your question by far is to either buy a plugin (perhaps the one you linked) or hire someone to write one. If you'd like to learn, there are a lot of resources online to help you start learning to write WP plugins.
