  In recent years, with the development of data warehouse and Web technology, more and more attention has been paid to multiple applications of the data in warehouse. However, data quality issue is one of the biggest obstacles to the success using of data warehouse project for many enterprises. So a data audit model is proposed and the relevant methods are studied in the study based on the characteristics of the telecommunications industry. Further, a three data layer audit method, consisted of audit mode data file level, record level and index level, is constructed during Extraction Transformation Loading (ETL) process. It can effectively improve the data quality of data warehouse.

  RFID-based location awareness is becoming the most important issue in many fields in recent years, such as ubiquitous computing, mobile computing. However, the RF system is noise-limited, which leads to the readers can’t read the information from tags timely and accurately, especially for RFID localization network. This study proposed a novel RFID indoor localization method based on Received Signal Strength Indicator (RSSI) and Packet Received Ratio (PRR). To do so, the environmental factors affecting the link quality are analyzed and the location awareness data is collected by RFID equipment using non-coherent Frequency Shift Keying (FSK) as modulation scheme and Not Return to Zero (NRZ) as encoding scheme. Then the relationship model between RSSI, PRR and distance is established based on the classic radio propagation model in localization field and theoretical analysis of the normal probability distribution of PRR is conducted. The experimental results show that our approach is valid and proper and also contributes to a novel perspective and theoretical support on the further study and application of RFID indoor localization.

  With the continuous development of society and the prevalence of computer and network technology. How to ensure the security of information in the course of transmission have become the most important things for people at present. With this background, we studied how to realize encryption and decryption of the RSA (Initials of Ron Rivest, Adi Shamirh, LenAdleman) encryption technology. This study mainly introduces the application of RSA algorithm in encryption and decryption, mentions the technology of digital signature. Also introduces in the process of implementation of RSA algorithm in Visual Studios environment and operation results. Using this system for encryption and decryption of information, theoretically, good results were obtained in safety and reliability.
