There is a problem ask you

Do a like 12306 online ticketing system based on B/S architecture, and the use of any technology, technically, to implement the logic of how complicated?

If on the estimated cost, need how many money?

CodePudding user response:

The largest can accommodate many people online ticketing oh?

CodePudding user response:

It is said that it took more than 200 million, isn't it

CodePudding user response:

In 300 million the ministry of railways, but there must be some of the water, technical things, not very understand, but must be considered when designing large amount of data and the problem of traffic, in addition to this, is the logic problems, a slight experience this aspect should engineers to design out is not easy! Now 12306 more than 200 million people online ticket at the same time,

But I think that this 300 million must have water, so I want to know how much cost, I know that software development is based on time and manpower to calculate costs, plus hardware and network operations, how don't have 300 million so much!!!!

So ask a post,

"The current 12306 online at the same time the ticket number has more than 200 million" the water is bigger

Will give a valuation system, first of all to have the original customer demand, and then assess the workload, sometimes also look at the customer's financial resources, such as we offered the customer take a week to do a small system, possibly can only sell for tens of thousands of small customers, but wealthy clients could sell for hundreds of thousands of (especially in institutions, government departments)

, that is to say, to give customers customized system is to define the price according to the customer's financial resources, financial resources is expensive, cheap, conversely without computing system design and manufacturing cost of the province, is that so?

CodePudding user response:

One more thing, customer resources, your service is a... So to do pay more... The price is high

CodePudding user response:

The whole a garbage, specially used for sick people,

You can look at the book the bible - the second edition "" programmer, the above estimated cost about its experience, this book can be downloaded in CSDN, link

Old problem, not to say that the railway ministry called IBM, sybase, oracle, etc., offer casually, as long as can solve the problem of peak ticket not scolded, how much more money to, no company can guarantee results
