Database Retrieval

In this paper, the importance of encryption retrieval technology in cloud storage is analyzed, and the current research status and problems of cryptographic retrieval and related technologies are analyzed synthetically. Cloud computing is a form of distributed computing, an online network service delivery and usage model that obtains the required services on an as-needed and extensible basis over the network. is a network of services and hardware and software collections of data centers that provide this service. Cloud computing is the evolution of parallel computing, distributed computing and Grid computing. The implementation of cloud computing includes software as service, utility computing, platform as service, infrastructure as service. Current Cloud computing ...

The necessity of database encryption large database management system platform is typically Windows NT and Unix, these operating system security level is usually C1, C2 level. They have user registration, user identification, Arbitrary access control (DAC), audit and other security functions. Although the DBMS on the basis of the OS added a number of security measures, such as access control based on permissions, but the OS and DBMS on the database file itself is still lack of effective protection measures, experienced online hackers will "bypass", directly using the OS tools to steal or tamper with the database files ...

User anonymity method for large-data-oriented personalized retrieval Kanghaiyan Xiong Li, a method of anonymous user's interest model based on the combination of difference privacy and p-link technology, is proposed to solve the contradiction between the potential privacy security of personalized retrieval technology in large data and enhance the performance of personalized information retrieval. First, the user's quasi-identifier generalization and add noise to meet the difference privacy protection requirements, maximize the accuracy of the query in the statistical database, while minimizing the probability of identifying individuals and attributes, second, based on the similarity between users ' interests to the micro-poly to the full ...

As a software developer or DBA, one of the essential tasks is to deal with databases, such as MS SQL Server, MySQL, Oracle, PostgreSQL, MongoDB, and so on. As we all know, MySQL is currently the most widely used and the best free open source database, in addition, there are some you do not know or useless but excellent open source database, such as PostgreSQL, MongoDB, HBase, Cassandra, Couchba ...

1.1: Increase the secondary data file from SQL SERVER 2005, the database does not default to generate NDF data files, generally have a main data file (MDF) is enough, but some large databases, because of information, and query frequently, so in order to improve the speed of query, You can store some of the records in a table or some of the tables in a different data file. Because the CPU and memory speed is much larger than the hard disk read and write speed, so you can put different data files on different physical hard drive, so that the execution of the query, ...

Basic Local Alignment Search Tool (BLAST) is a similar structure retrieval program designed to detect the similarity of all available sequence database queries. The heuristic algorithm is used for local lookup, and it can detect the relationship between a similar sequence of individual regions. It can run a complete executable file locally, and it can be used for private, local databases, or to run blast searches in a copy of the NCBI database download. It supports Mac OS, Win32, LINUX ...
