c/s--client/ server, simply speaking, the client computer needs to install proprietary software to communicate more servers, just like QQ. Mainly through the mechanism of the message to pass (of course, can also write their own protocol, the game is done.) )
b/s--Browser/service side , you can communicate with the server as long as you have a browser, no need to install a dedicated client, communication protocol using the HTTP protocol ... Like WEBQQ.

Instance is a means of accessing Oracle database.An Oracle instance corresponds to one and only one Oracle database, and an Oracle database can have multiple instance to access him, which means Oracle instance and Oracle Database is a many-to-one approach. In general, we install Oracle on a single machine in instance and database one-on-one, but in the case of an Oracle cluster (Oracle RAC Environment) He is a multiple instance corresponding to a database.Oracle instance has two components:

b/s structure, that is, Browser/server (browser/server) structure, Web application, that is, the program running in the browser for the Web application. Programs that run in a browser are BS-structured programs. BS application does not need to have its files locally. Just use the browser to enter the ULR address.

View the simple table structure and JAVA data structure from the perspective of java Data Structure1. Preface:
When we talk about collections in programs, we often come to our minds, such as ArrayList and aggregate list and HashMap. Of course, when talking about ArrayList and rule list, most of us know that ArrayList queries are fast and operations are slow. Slow list query speed, but fast operation speed.

Example: one-element polynomial and its operationOne-dimensional polynomial: f (x) = a0 + a1x + a2x^2 + ... + a (n-1) x ^ (n-1) + an x^n main operation: polynomial addition, subtraction, multiplication and so on how to express the polynomial. Key data for polynomials: polynomial

How did you learn the data structure? One of my students called Cai Yao and nicknamed Cai Yao ". He has been communicating with me through e-mail some time ago. He talked about some of his work experiences and was deeply touched. Here I will talk about the story of coriander.
He told me that when I was a student, I didn't really have a good data structure at all. I often skipped classes, and I barely p
