	abstract = {In this study we present how some version control history based metrics affect maintainability of the source code. These metrics cover intensity of modifications, code ownership and code aging. We determine the order of source files based on each analyzed metrics, and compare it with their maintainability based order. As a cross-check we perform a comparison test with post-release defects as well. We performed the analysis on 14 versions of 4 well-known open source software systems. The results show high correlation between the version control metrics and relative maintainability indexes, in each case. The comparison with post-release defects also support the results in most of the cases.},

	abstract = {The number of software systems under development and maintenance is rapidly increasing. The quality of a system{\textquoteright}s source code tends to decrease during its lifetime which is a problem because maintaining low quality code consumes a big portion of the available efforts. In this research we investigated one aspect of code change, the version control commit operations (add, update, delete). We studied the impact of these operations on the maintainability of the code. We calculated the ISO/IEC 9126 quality attributes for thousands of revisions of an industrial and three open-source software systems. We also collected the cardinality of each version control operation type for every investigated revision. Based on these data, we identified that operation Add has a rather positive, while operation Update has a rather negative effect on the quality. On the other hand, for operation Delete we could not find a clear connection to quality change.},
