A configurable data subscription and publishing system and its method

Abstract

The invention discloses a configurable data subscribing and publishing system and a method thereof. The system comprises a data publishing module and a data subscribing module; the subscribing module comprises a condition input module and a logic processing module; the data publishing module is used for describing information of heterogeneous data by a heterogeneous data description standard file and carrying out association on the described heterogeneous data and other related data by configuration; and the data publishing module is also used for providing corresponding configuration information for data description standard conversion by a configuration file of the data description standard conversion. The requirement of a user for cross-table subscription can be met; the problem of combining the subscription conditions is solved; and when each functional module is modularized and designed and the system is convenient to transplant, the system has good user experience. The method comprises two steps of data subscribing and data publishing, solves the combination problem of the subscribing conditions and the isomerism problem of the data in the subscribing problems of massive heterogeneous dynamic data and implements the combined subscription.

Description

technical field [0001] The invention relates to the field of data exchange, in particular to a configurable heterogeneous data subscription and release system and a data exchange method using the system. Background technique [0002] With the rapid development of information technology, large-scale, dynamic and diverse types of business data have been accumulated in practice. How to obtain the required data from these massive heterogeneous dynamic data in a timely and efficient manner is an urgent problem to be solved in the current data exchange field. Data subscription and publishing technology is an effective way to solve the above problems by proactively providing data according to user preset conditions. [0003] For the subscription of massive heterogeneous dynamic data, it is not only necessary to consider the combination of subscription conditions (that is, the combination of AND or non-logical relations), but also the heterogeneity of the data (different data model...

Problems solved by technology

However, the existing patents of the same kind cannot configure this information, and can only subscribe to the fields of this table; at the same time, when performing conditional subscriptions for a large amount of heterogeneous data, it is necessary to configure the type of heterogeneous data, but most of the existing similar patents are for each Design a subscription scheme for different types of data, including the way of adding subscription conditions. There is no unified heterogeneous data description standard to follow, so it is difficult to solve the subscription and publication of heterogeneous data and the combination of heterogeneous data subscription conditions.
