Design of Safe Information System for Gas Well

In the gas well information system,the number of application node is large and its position is distributed,every application node need to deal with large data and share data stably and safely between each other.Technology of distributed database is used in order to solve the problem.Introduces its characteristic and basic principle at first,concludes the characteristic and requirement of data in the high-sulfur gas well safety information system,and then expatiates the design and realizing process of distributed database technology in the high-sulfur gas well information system by configuring database access mode,setting up database link,optimizing database query.After checking by practice,the method can solve the contradiction of distributed data,share each other and concentrated management in effect,and supply a little reference to solve the remote database management system.
