DBMS Transactions for handheld Devices

Handheld devices are very popular today. They are used for personal and enterprise applications like Health-care and Micro-banking. These are complex applications and require effective management of data. Applications have to query and also update remote databases.

Updates typically involve transactions. Transactions have to maintain the ACID properties at local as well as global level. Transaction management has to capture the movement behavior, frequent disconnections and small communication ....etc

Four years ago Palm created the first successful PDA. Today it holds an 80% share of the market for handheld computers. Its most serious competition is a family of devices from various vendors based on the Windows CE operating system. In some ways the competition between these two systems is reminiscent of the earlier Macintosh-Windows battle. Users become familiar with a device and develop strong preferences.

A Wearable computers make possible useful deployment of technology in situations and environments which were previously impervious to technology.For instance, assembly and repair personnel often need to keep both hands free to perform a given task. Moreover, they often work in environments far from the typical office setting where mobility is essential. Immobile computers, such as desktops, are of little value in such environments, and portable solutions, such as laptop and handheld computers, are little better.Wearable computers, on the other ....etc

Data collection Using Handheld devices

Hand Held devices are becoming more and more popular these days. They are packed with a lot of features that a common man or an advanced user would want. The smart phones currently available in the market have more processing power and memory than the desktop PCs 6 years ago. These devices are connected devices with many communication options like infrared, Bluetooth, Wifi, SMS and GPRS.

In this project the requirement is to study the working of 100 filed staff of Health Action By People and ....etc

The history of computer technology has involved a sequence of changes from one type of physical realisation to another --- from gears to relays to valves to transistors to integrated circuits and so on. Today's advanced lithographic techniques can squeeze fraction of micron wide logic gates and wires onto the surface of silicon chips. Soon they will yield even smaller parts and inevitably reach a point where logic gates are so small that they are made out of only a handful of atoms; i.e. the size of the logic gates become comparable ....etc

Since the development of the ENIGMA (the first digital computer), computers have inspired our imagination. In this period came the World War II code breaking machine designed by Alan Turing, and Von Neuman's ENIAC which can be called dinosaurs compared to present day PCs. In the earlier days, computers were so huge that it took an entire building, or at least a floor to occupy one. Computers of that era were very slow by today's standards. In the non-ending struggle to increase computing speed, it was found out that speed of electri ....etc
