Attendance is taken at various places like schools, colleges for students and login logout time for employees in industries and offices. The existing system is done on paper and it consumes lots of papers and it is of manual work. It has less accuracy. In order to reduce the usage of paper RFID based attendance system is used. It is an automated attendance system where Rfid tags are used. This is the easy way to take the attendance without any physical contact. In this project we use RFID Reader, RFID Tags, LCD display, which are interfaced withATMEGA8 Microcontroller. The Rfid tags are given to the students, with their roll numbers as their tags. When the tag is placed near the reader, the data is transferred to reader due to the radio frequencies. Reader then transfers data to the microcontroller. Microcontroller checks for the data continuously, if any data is received, microcontroller compares the data in data base. It eliminates the duplicate entry of data and reduces errors in time and entries.

The sharp increase in fiscal deficits and public debt in most advanced and several developing economies has raised concerns about the sustainability of public finances and highlighted the need for a significant adjustment over the medium term. This paper assesses the usefulness of fiscal rules in supporting fiscal consolidation, discusses the design and implementation of rules based on a new data base spanning the whole Fund membership, and explores the fiscal framework that could be adopted as countries emerge from the crisis.

Environmental monitoring plays a very important role in the activities of predicting and protecting environments and society. The activities are included of monitoring environmental parameters continuously, predicting and evaluating the effects of environments on society, warning immediately the abnormal phenomenon or pollution due to environmental changes, making data base etc. In the paper, we will present our proposal of design and implementation of a kit monitoring environmental parameters such as temperature, humidity, pH, salt percentage, water level, etc remotely through internet. Obtained data will be monitored, handled, managed, reported. The system has been used to monitor environmental parameters to evaluate the waste water in industrial zones in Hochiminh City, Vietnam.

This paper describes the design and implementation of a distributed medical data base. Basic to this concept is a network of minicomputers, each of which possesses files which can be accessed throughout, the network by a protocol involving the NAMEs of the data fields. Physical and logical descriptor maps for the files provide mechanisms for protecting privileged information as well as tailoring the appearance of the data to suit the needs of jDarticular users.
