Artificial guard

In addition, website security is very important one link is man-made guard. Some companies are not equipped with a full-time webmaster, web server since put into operation after a few buyers,Email Marketing perhaps for weeks or even months to maintain. This long time indifferent attitude is also difficult to ensure site safety, if hackers during which broke through the firewall intrusion detection system, and the hobbyhorse or virus allograft in the server, it is likely to lead to substantial browsing the web users infected with the virus, the direct consequence is the company's image and reputation impact.

What is more, some of the network administrator to website server into since the genus a network world, unauthorized erection of FTP, forum or other network services, system resources occupied do not say, more to hacking system provides an opportunity.

The disadvantages of domestic enterprises website

Many enterprises have invested considerable funds to set up their own sites, but for a long time, these sites tend to cease to exist except in name, Baconian rise nothing more than these types of phenomena:

The 1 site of long-term do not update the site, some enterprises have several years not updated, even companies have moved but there is nothing on the webpage, caused a lot of trouble to the customer, orders fall into other companies is not surprising.

2 site never customer desired content. There are a lot of customers love through the website undertakes comparative, but some enterprises website can provide the information is too small, often these data from the third party sites can be found, the result is often customers and provide complete information enterprise first contact.

3 the information provided on this site is too much too miscellaneous, no key, not only a waste of investment and operating costs, customers looking for the information is not easy. So successful enterprise website is how to locate? According to the survey, 26 in the home of the world's top 500 enterprises in the United States, 76.9% of the enterprises to set up a special" products with the brand " column; 38.5% of enterprises in website home page with the " online services " column, the user can enjoy the convenience of online service; 96.2% of enterprises in website home page is provided with a" contact us " column, click the user can directly contact with the enterprise, feedback to the enterprise a variety of user information.

In China the same into the world's top 500 enterprises, 75% enterprises set up a product introduction column, but can provide online service function of scanty, only half of the site to establish a" contact us " column. From these figures contrast is not difficult to see,iPhone Application development the domestic site and not the network marketing consciousness, do not know how to use web marketing, especially for the site of the actual effect is not good, the fixed position of the website still is a primary product information site, with foreign forming network consulting, network orders, such as one-stop customer service network the complete network marketing services, there is still a considerable gap.

JSP technology is strong

( 1) write once, run everywhere. At this point the Java is more than PHP well, apart from outside the system, code need not make any changes.

( 2) multiple platform support system. Basically be on all platforms of any development environment, in any environment for deployment of the system, in any environment extends. Web Content Management System Compared with ASP / PHP limitations is obviously.

( 3) strong scalability. From only a small Jar file can be run in Servlet / JSP, to a server cluster and load balance, to multiple Application for transaction processing, message processing, a server to hundreds of thousands of servers, Java shows a great vitality.

( 4) a diverse and powerful development tools support. Of this and ASP like Java, there are many very good development tools, and many can be obtained free of charge, and many of them have successfully run on multiple platforms.

JSP vulnerable

( 1) and ASP, Java some advantage is its fatal problem. It is due to the cross platform function, in order to extreme expansion ability, so greatly increases the complexity of the product.

( 2) Java operating speed is class memory resident to complete, so it can in some cases by the use of memory than the number of users is indeed" the lowest price performance ratio .". On the other hand, it also needs to hard disk space to store a series of .Website Development Java files and. Class files, as well as the corresponding version of the file.

In 1, the layout of the web site design

The layout of the web site design through text and graphical space, express and go with us. A good web designer should know which text graphics on what position, in order to make the entire website with. Multiple page site layout design requirements of the page is an organic link between reflected, in particular to deal between pages and pages within the order and content of relations.

2, website unity of form and content

Want to be rich and varied forms into uniform page structure. Application of contrast and reconcile. Symmetry and balance. The beauty of rhythm and cadence. For example, in the page design, symmetry principle equilibrium sometimes makes the page is dull, but if you add some dynamic text. Pattern, or the use of exaggeration to the performance of the content can often achieve better results.

Solar street lamp

Solar streetlight is a method of using the solar energy as the energy of the street,Gaosuibuyou Thailandsolar panels because it is not affected by for movies, not ditching embedding, consumption of conventional electric

Solar street lamp

Can, as long as the sunlight can be installed locally, so by the widespread concern, but also because of its no pollution to the environment, which is called the green environmental protection product. Solar street lamp can be used in urban parks, roads, lawn lighting, but also for the population density of small, traffic inconvenience underdeveloped economy, lack of conventional fuels, it is difficult to use conventional energy generation, but solar energy resource-rich areas, in order to address these areas people 's home lighting.

Solar power

Direct converting solar energy into electric energy, and stores the electric energy in a capacitor, for use when necessary.

Off grid solar power systems

Off-grid solar power systems, solar controller ( including 1 photovoltaic controller and the scene complementation controller ) to the power to regulate and control, hand, after adjustment for energy to the DC load or AC load, on the other hand the extra energy to the battery storage,solar modules when the hair can not meet the need of electric load, solar controller and the electrical energy from the battery to the load. A full battery, controller to control the battery was not overcharge. When solar energy is put out, solar controller to control the batteries will not be over discharge, protect the battery. The performance of the controller is not good, the battery life is greatly affected, and ultimately affect the reliability of the system.

2, solar battery is the task of energy storage in the night or on cloudy days, in order to guarantee the electricity load. In 3, the solar inverter is responsible for changing DC into AC, AC load used for. Solar energy photovoltaic inverter is the core component of wind power generation system. Due to the use of relatively backward area, remote, difficult maintenance, in order to improve the overall performance of the PV wind power system, ensure long term stable operation of the power station, the inverter reliability raised very tall requirement.toner As the new energy power generation cost is higher, the solar inverter high running also appears very important.

Off-grid solar power systems the main products classification of A, photovoltaic components B, C, D fan controller, inverter, battery E F, wind / photovoltaic power generation control and inverter integration power supply.

The mounting bracket to fix?

Generally use the cement pier, expansion bolts or wire rope is fixed in several ways, according to choose the best way fixed roof.
