Remote data query method, system and device

Abstract

The invention discloses a remote data query method, system and device, which are applicable to data query processes among different local area networks. The method comprises the steps that: a query server generates a query mail including query conditions in an attachment according to the query conditions inputted by a subscriber and target server information and transmits the query mail to a target server; the target server receives the query mail and analyzes the query conditions from the attachment of the query mail; a query operation is executed according to the analyzed query conditions, and then a reply mail including query results in an attachment is generated and is returned to the query server; and the query server receives and analyzes the reply mail, analyzes the query results in the reply mail and presents the query results to a corresponding subscriber. The remote data query method, system and device realize the data query among systems conveniently and quickly, without occupying a great amount of public resources, and the use and maintenance costs are low.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an electronic mail (Email)-based remote data query method, system and device for inter-network data query. Background technique [0002] At present, with the rapid development of Internet technology, software systems in the Internet are gradually enriched, and their number and types are increasing. The software system on the Internet involves various aspects of business, and as the degree of information sharing becomes higher and higher, the possibility of related data query among various systems is increasing. For example: the software systems used to provide various services within an enterprise query each other for relevant data. [0003] Usually, if the two software systems that need to perform data query are located in different local area networks, then they need to solve the intercommunication problem between different local area networks for data query, which is gen...

Problems solved by technology

[0005] 2. By using different public network IPs to connect two software systems in different LANs, it needs to occupy a lot of IP address resources, and the current public network IP resources are very tight

[0007] Although the various solutions in the prior art realize mutual query of information and data between two software systems in different local area networks, they need to occupy a large amount of public resources, such as: VPN virtual private line, IP address, domain name, etc. , thus straining public resources

Moreover, the implementation method of the existing technology is technically difficult, complicated to maintain, and the construction cost, use cost and maintenance cost are all very high
