Embodiment 1

[0078] like figure 1 As shown, a heterogeneous database fusion access system, including:

[0079] At least one database interface; used to receive, transmit or share multi-source heterogeneous data information, the database interface is a database interface of different data models in the network architecture, at least Oracle data interface, SQLServer data interface, Unix data interface, WindowsNT data Interface or Linux data interface; by setting in this way, it can realize the interaction of various data information, and can realize the interaction of various information with external devices.

[0080] The information distribution module is used to distribute the multi-source heterogeneous data information received, transmitted or shared by the database interface according to different data channels, wherein the information distribution module includes a communication protocol mapping module, a multi-data interface and an information sending and receiving module, Wherein th...

Embodiment 2

[0091] In the present invention, the method for extracting data by the data feature extraction module is:

[0092] Set the data category of multi-source heterogeneous data information to n, and the fused multi-source heterogeneous data function is represented by an i×j order matrix:

[0093]

[0094] All data information can be constructed into a data matrix through formula (1), so as to facilitate the processing of various forms of multi-source heterogeneous data information. In order to improve data computing capabilities, the data information of any row and column in multi-source heterogeneous data information can be recorded as α ij (ω f ), then:

[0095]

[0096] In formula (2), when extracting data features, by extracting multi-source heterogeneous data information, assuming that the extracted feature attribute is recorded as j, then under the action of j, the extracted multi-source heterogeneous data information function is α ij ( ), then i represents the frequ...

Embodiment 3

[0101] In the present invention, the method for realizing multi-source heterogeneous data dimensionality reduction by the feature data dimensionality reduction module is:

[0102] Step 1: Set the multi-source heterogeneous data information, and record the multi-source heterogeneous data reconstruction data as matrix A, then:

[0103]

[0104] In formula (4), n represents the number of multi-source heterogeneous data, where k is the data dimension of multi-source heterogeneous data information, and the dimension data information is expressed by the formula as k=n-(u-1)r, where r In order to collect the time delay of the data dimension, u is the embedded dimension set in the data dimension reduction process; by expressing the multi-source heterogeneous data reconstruction data in the form of matrix, the aggregation of different data groups can be realized, which is convenient for data research , improved data collection capabilities.

[0105] Step 2: Then calculate the value...

Description

technical field [0001] The invention relates to the technical field of network databases, and in particular to a fusion access system for heterogeneous databases. Background technique [0002] With the rapid development of network data architecture, network database technology has gradually developed. At present, a considerable number of enterprises and scientific research institutions have accumulated a large amount of data stored in different forms and dependent on different database management systems. Based on the rapid development of computer technology, there are various heterogeneous data information in different data layers. In the era of big data, information data is growing explosively. It is difficult for traditional relational databases and emerging NoSQL databases to deal with these problems comprehensively and efficiently. challenge. How to process these data information is a problem that needs to be solved for the further development of enterprises. [0003]...
