When it comes to software development, it's impossible to say that the database has to say three paradigms in fact, there are six database paradigms in addition to the 123th paradigm to There's the fourth fifth paradigm and a BC paradigm here we only discuss three paradigms interested friends can find some professional books for further study First Paradigm (1NF) The first paradigm is that each column of a database table is an indivisible basic data item cannot have multiple values in the same

Real applications need to interact with real servers. mobile applications and emerging Chrome desktop applications may be an exception, but for all other applications, whether you want to persist data to the cloud or interact with other users in real time, you must allow applications to interact with the server. To achieve this, Angular provides a service called $ http. It provides an extensible list of abstract methods, making interaction with the server easier. It supports HTTP, JSONP, and COR

. However, ADSL technology also faces many problems. Although its outstanding features can meet basic broadband needs, it cannot meet the needs of high-bandwidth services based on videos. However, another DSL technology can easily make it all possible. This is the VDSL technology. 1. Overview of VDSL and its working principles In short, VDSL is a fast version of ADSL. With VDSL, the maximum download rate within a short distance can reach 55 Mbit/s, and the upload speed can reach 2.3 Mbit/s. Both

Traditional network technologies have been left behind by history, so popular new technologies must adapt to social development. The formation of networks in the family also faces many problems, the home network standards and specifications are described here. Wireless voice network-when each wireless phone can view and manage up to four common telephone service (POTS) lines, multiple PCs can be used on the LAN at the same time. The mobile phone displ

Broadband ip man-based wireless and IP multi-service access applications The voice service is still the main growth point of profit of domestic operators. While building a broadband MAN to implement data services, it also carries voice services on the established data network to avoid re-laying the cables, so as to achieve the convergence of two network data and voice at a low cost, moving towards triple play will be an inevitable choice for emerging operators.UTSTARCOM's mSwitch Softswitch plat

services.Common calls follow the existing call procedures and standards.One-to-one call can be divided into two types: Synchronous call and forward call. When a user calls one-to-one call, the softswitch switches the call to the application server. The application server obtains user data based on the called Number: Same-vibration or forward call, and the transfer number table. The application server will initiate a call to the same vibration number according to the user settings, or call the n

Too many VoIP service providers want to sell you their "full solution", from the phone number on your desk, from different sites to the WAN and public exchange Telephone Network (PSTN).

Enterprises that have trouble with VoIP must have had this situation, because they jumped onto a carriage and jumped to the cutt
