Mobile applications are to enter the e-mail from the server and enterprise application software connected to a higher level. As a result, mobile devices has become a business intelligence front-end applications, which can store and access to local information, and then once connected to corporate headquarters, will be able to exchange information. Handheld devices are now becoming mainstream, has become the new front-end applications, and it also brought about by the intelligent and efficient machine to use a never before used a computer at work. Today, handheld devices can be the first to use the equipment to improve efficiency, reduce costs and bring about competitive advantage. In the future, they will be bound to be an essential tool for competitive advantage, especially in the need to have a large number of employees working at the scene of the industry. However, this new application form has many different characteristics of the PC, thus affecting the development of appropriate software. t is no longer just a toyIT personnel for the mobile enterprise application development to understand this new trend of the first aspect is that the handheld device is no longer in charge of the company are in the hands of the toys, it became employees and outside companies a way to keep in touch. They are real productivity tool, and London, PSM Mobility's chief technology officer Steve McCorry said, is a popular blue-collar workers for the development of on-site service applications. Service every morning to do the first thing that came to the office to receive a single work. And then going to and from work and return to the office, the completion of the work of a single hand. PSM Mobility is a distributor to companies for the sale of on-site support for the handheld device, which is based mainly on the reinforce Motorola's Windows Mobile-based devices. The company started by selling hardware, and later into the development of custom applications in this area in order to meet customer demand. PSM customers often have a product that can dispatch headquarters staff and field staff of the exchange between those who carry out the work of a single digital processing and automation in order to be able to send down the same day the company to complete all the tasks. Such products are often reinforced handsets through security lines to connect to the Internet company's scheduling software. It has another advantage: scheduling can re-deploy the same day of service personnel to respond to emergencies. Only work to enhance the efficiency of this is easy to prove the need to purchase the rugged handheld devices.Second, do not repeat the mistakes of the times PC To learn more about the second aspect is, IT staff in the hand-held devices do not repeat those mistakes of the PC era. Specifically, they equipment that should not be allowed to be connected to a few small islands of automation. Although IBM introduced the first PC has over 25 years, but many organizations are still from the spreadsheet in the company's access to important data, and then transferred to the network application software. However, the browser simply by visiting the enterprise server application software is not enough, even if this is due to the use of multi-band (Wi-Fi and cellular) devices, IT staff can not guarantee that each site has its browser-based application software The need for connectivity. In connection between the failure of such devices need to store data locally, to some extent, the data processing functions, to connect to resume, and be able to automatically transmit the data. In addition, both the independent program or browser-based programs, they are unable to provide on-site work environment often requires flexibility. Therefore, IT staff should leave more choices for themselves. To do so, at the same time in order to be able to hand-held devices simpler, faster development of custom applications, the key is the use of middleware, specifically the use Syclo LLC's Agentry platform. For example, PSM Mobility of a company's customers deployed thousands of PC. It hopes to have a mobile asset management software to track its own hardware and software installed in order to track not only their own records, but also to track customer records. The challenge in that they deal with a lot of home organization, would like to have accurate records of assets (including those who are to replace the PC) of the major commercial banks, some of the requirements of a very loose organization. Thus each client, the data acquisition and reporting parameters vary, in some cases, customers may change the way in the development of information request. Handset application software is often very flexible, so for handheld devices based on the solution is, it is difficult to take into account the requirements of such a change. PSM solution to the problem is the use of handheld devices in Agentry on the development of easy-to-custom front-end form, to connect to the Internet through the company's easy-to-back-end database customized to meet the requirements of each customer. The PSM is another customer for the office building to provide office management and guard services. At first it PSM requirements for on-site maintenance team to provide a mobile system for tracking the activities of the employees in order to billing. But other customers have complained that their staff in the field of office long enough. As a result, the demand becomes: How to prove that someone Given the limited time there. Approach is to use the built-in GPS hand-held devices, such as the Symbol MC70. Syclo's a great tool to increase access to time-tag the GPS coordinates, as part of a single work, as they can prove they are indeed time to the customers.As the PC has its own set of applications (as distinct from the server application software), handheld devices represent a new type of calculation, it also has its own set of unique features. By and large, with the location of these features, and some at the time of the incident access to records; provide some near the place. For example, the handset can be used to access the many information, such as the working group at a set time, location, the work done (including the use of bar code scanning equipment has been installed or has been replaced), as well as to prove the work has been completed single customer signatures .Four on-site working environment for the physical size of the different needsIT staff to understand the fourth aspect is that the on-site service staff for handheld devices in the physical size requirements different from those in charge of the company. Small, delicate and easily damaged handheld devices can not do all day is not suitable for large, heavy tools of the staff. But they need to be able to do the same in the pocket or tool belt on the equipment because they do not sell to manipulate Proton flat-panel computer or portable computer.Five more intelligent applications Once the staff has been smart devices, will soon start asking for more applications. For example, on-site service personnel often need to track expenses and mileage, then why not develop a software application to enable them to have access to this data in real time, and then report directly to the data to the headquarters of the accounting software does? They are usually required to carry Yida Luo service manuals. If these manuals through digital processingequipment that can be deposited or SD memory card, then the companies do not need to print and distribute paper-based manuals, as long as you can automatically download updates to ensure that everyone has the hands of the latest version of the Manual. The on-site service staff is always on-hand has the necessary information, do not need to look for the car, or fall on the home, do not have as tools and spare parts as needed to carry bulky manuals. So I chose to use the reunification of the kind of hand-held devices, to consider the application scalability. Finally, the battery life of the whole day to prepare for the working environment at the scene, and no charger in the vicinity of the situation is critical. It is clear that if the battery for a long time with no electricity, no longer function of strong equipment is of little use. This is the Tablet PC-oriented blue-collar workers at the scene of the application software is often not the best choice for another reason - because the Tablet PC screen size, battery often can only be used 34 hours. Although the battery life over the past few years to improve greatly, but it needs the power supply has also increased the number of peripherals many. Therefore, to address the key is to get to the low-level device management software to optimize the equipment, as far as possible in order to extend the battery life. Due to the use of Wi-Fi, Bluetooth, infrared and cellular connections, and so on, the battery is likely to only three hours. But as long as the adjustment of management functions, which shut down power peripherals (only when they need to open), you can greatly extend battery life in order to meet the requirements of the use of a full working day. For example, only a single work, ready to send, open Wi-Fi and cellular connectivity; bar code software to run only after the activation of infrared connectivity, and so on.
