3 years, 1 month ago
The market of electronic commerce both in the world and in RuNet very actively develops, despite crises and other negative phenomena. In the world in year average growth rates according to eMarketer make about 18-20% a year, in Russia and Ukraine growth rates reach 17-18%. These are about 3-4% of the general retail in Russia (in Ukraine slightly less, the market is developed less and now deep crisis) and to 10-12% in the USA and other developed countries. The average level in the world makes about 6%. The only exception, last year in Ukraine because of deep economic crisis the market has not grown in dollar equivalent, but for the local companies it is chance to overtake missed earlier. The most interesting that all of us still are in stage of origin of the market. According to many forecasts the share of electronic commerce in the general retail will reach 20% in the next some years. For the companies of this sector ignoring of this market is equivalent to death today tomorrow.



It is interesting as well that fact that many largest players of electronic commerce in the USA have offline roots, and the USA are certain litmus piece of paper, the catalyst of the market which shows us that will occur in our markets in the same segment in 3-5 years. To it already there is confirmation: in Russia number of large online stores belong large offline networks for a long time and absorption proceed. In Ukraine with it it is more difficult though it is process actively goes, so several months ago the Fokstrot company has redeemed 100% of Sokol.ua online store

As we deal with Symfony2, we will need to make the elementary controler, to register to it reception and to pick up work line rack. Depending on specific case, it can with be done in the separate bandl, or in any of the already available.

Serious projection of serious shop. Part 1. We researched and thought over a functional

4 years, 11 months ago
Not so long ago I writing article about projection of the big sites on an example of a social network with a similar title: «Serious projection of serious sites». Today I wants to talk about one of the main spheres of our activity – electronic commerce, namely about projection of e-commerce shops.

It are a cycle of articles more experts, considerably it are more profound, than all my last to article in this area. In article I will tell about the largest e-commerce shops of the USA, China, Russia and Ukraine, I will tell as marketing influenced projection, I will show detailed Mind Map of a hypermarket, I will describe 57 main units of e-commerce shops for an exterior (consumer) part and more than 50 units for an internal part (administrative), I will show interfaces of shops and still a lot of the useful.

On the Internet personally I am t by e-commerce shops and technologies of sales with far 2005. For years of operation my judgement on this question strongly evolving. Once I thinking that the e-commerce shop are simple enough site with the point of view of the developer or the expert in marketing, it seeming to me that all shops was similar against each other and enough once to receive a pool of knowledge whom it will be then possible to use many years without special changes, after all the Internet shop are only type of a site for sale of the goods and at first sight there are nothing difficult in develop the next shop with a similar functional, but with other goods. Actually all are much more difficult and the more I learns about e-commerce shops, the I understands more that in this question the nobility all are impossible, even the one trifle in the interface could change profit of shop to thousand dollars, and for the big players this "trifle" could cost millions. This singularity of electronic commerce did requirements to sites and experts who done them, madly high. Hardly more low I will show many interesting digits who will prove my statement.

Earlier I already writing article about technology of projection of the big sites who, by the way, having very great popularity in a Russian-speaking and English-speaking segment of the Internet: «Serious projection of serious sites». Projection of an e-commerce shop though had the similar sequence of actions describ by me in last article, but the technology all the same strongly differed, therefore let's consider it in the smallest particulars. On a course of article I will refer on last not to repeat, and in this I will emphasize distinctions.

As we d API for a social network (REST API for WEB)

4 years, 11 months ago
I in the operation often faces with different new concepts, ideologies and projects. In the core of that I participates in development of different big projects, in each of which I meets something new. Today I wants to tell about the experience with REST API. Ideologies who to me somehow time could be appl by development of an one social network.

About it it are already much wr, and still something the complete, allow to find all details necessary for me in an one place when I only starting to be engaged in it, in Russian-speaking edition I doing not meet. I will try to collect that it were possible to clarify, by samples, errors and constant searches in operation with various projects. So, we will start!

I wants to make a reservation at once: REST for me — it, first of all, ideology of whom I thinks much and are gentle. And, if someone are not ready to accept it such what it are — it is not necessary to read further this article. The programmer always had a heap of the useful affairs in which it are possible to be engaged while the understanding of necessity to write learn interfaces came and to hide for them simplicity logic of applications of any complexity …

At once should stipulate that I am a programmer, instead of the writer and are my first article. Probably, it turning out chilly, but we here all technicians, I hopes, will be interesting. In article I will describe the experience with REST API. I will try to make article of general-purpose that this ideology on my article could be appl for any Internet project.

Now give in sequence.
