Managing those projects is based on several software development methodologies. One of those methodologies is software version control, which is used in the majority of worldwide software projects. Although existing version control systems provide sufficient functionality in many situations, they are lacking in terms of semantics and structure for source code. It is commonly believed that improving software version control can contribute substantially to the development of software. We present a solution that considers a structural model for matching source code that can be used in version control.展开更多

Many tools exist to support the initial creation and management of changes to text-based requirements. The most popular commercial solutions use a centralized server to host a database with a front-end desktop or web interface. Some downsides to this approach include user interface bloat, server costs, and an inherent disconnection from the project’s source files. To provide an alternative to traditional requirements management, Doorstop was created as a tool to allow requirements to be stored as text files in version control. This solution allows a project to utilize its existing development tools to manage versions of the requirements using a lightweight, developer-friendly interface.展开更多

The checkout mechanism and multi version mechanism are two kind methods of solving the problem of long transactions. In this paper, we present a Shallow Version Management mechanism to realize multi version mechanism in spatial database. And we introduced a increment storage and dynamic version views building method to improve efficiency of storing and consulting. We also illuminate how to resolve the problem of long transaction concurrency control in spatial database by using multi version mechanism. At the end of this paper, we introduce some required means to version management in spatial database, like converge, compress and delete.展开更多
