Embodiment 1

[0031] A software module division method based on Markov clustering. First, the software is discretized into a function set F of multiple functions, and then the functional relationship matrix R is formed through the data flow between the functions in the function set F. Finally, the function matrix R is the object, and an adaptive software function division module is formed through Markov clustering; the specific operation is:

[0032] Step S1. Discretize the software into a function set F of multiple functions: For software containing n functions, construct a function set F={f 1 , f 2 ,..., f n}, where f i (1≤i≤n), f j (1≤j≤n) is a function in the function set.

[0033] Step S2. Forming a functional relationship matrix R:

[0034] First set the functional relationship matrix R=(r ij ) n×n ;

[0035] then set r ij The value of w is the function f i with function f j The number of data items that flow directly between them.

[0036] Step S3. Taking the function mat...

Abstract

The invention provides a software module division method based on Markov clustering, which comprises the following steps of: firstly, dispersing software into a function set, forming a function relationship matrix through data flow among functions, and representing the tightness among the functions by using the number of data items directly flowing among the functions; and then forming a self-adaptive module division method through Markov clustering by taking the functional relationship matrix as an object. By means of the operation, rapid and stable software function module division is achieved without setting the number of modules in advance.

Description

technical field [0001] The invention belongs to the technical field of software engineering, and in particular relates to a software module division method based on Markov clustering. Background technique [0002] Software design is a very important stage in the whole software life cycle. In software design, an important task is to divide the modules and classify each function into corresponding functional modules to form a software architecture. Reasonable module division can optimize the software system architecture, which is of great significance to the development, use and maintenance of software. The module division of software is a combination of software functions around the goals of high cohesion and low coupling. At present, most of the work still depends on the experience of designers, and the division results are not uniform and lack basis. How to give the division results under the premise of reasonably evaluating the relationship between software functions th...
