Generating UML class diagram from source codes using multi-threading technique
… This information includes generating several diagrams and specification documents that describe the implemented software. The UML class diagram represent a valuable source of information even after the delivery of the software. Class diagram extraction can be done either from software’s source …

Specification of vertical semantic consistency rules of UML class diagram refinement using logical approach
… design in software development industries with a class diagram being the most frequently use diagram. Despite the popularity of UML, it is being affected by inconsistency problems of its diagrams at the same or different abstraction levels. Inconsistency in UML is mostly caused by existence of …

A Comparative Analysis To Validate The Benefits Of Formal Versus Informal Software Model Transformation
… has been carried out on transforming UML class diagram models to object-oriented relational databases, which yield significant results. One approach to transformation may involve the use of formal (mathematical) techniques, while other approaches may rely on informal techniques to …

Applying case based reasoning and structural similarity for effective retrieval of expert knowledge from software designs
… of a software product and, in the case of a class diagram, contains information about its structure. It is therefore possible to extract knowledge about a software application from its design. For a human expert an important aspect of a class diagram are the semantic tags associated with each …

Attributes sanitization in object-oriented design to improve database structure
… Until late 1990’s, object-oriented introduced class diagram. However, designing a good database is still a serious issue. Some of the issues are very difficult to handle such as consistency checking between system design and database design, redundancy of data, mismatch of the data structure …

A novel model for improving the maintainability of web-based systems
… of lines added and deleted for components in a class diagram), and nRev (total number of revisions for components in a class diagram). Our results gave an indication that there is a possibility for a relationship to exist between our metrics and modifiability time. However, the results did not …

A DSL for defining instance templates for the ASMIG system
… For example, if a model is represented as a UML class diagram, the instances of this model are UML object diagrams. Model instantiation has several applications: finding solutions to problems expressed as models, model testing and test data generation. There are systems that automatically …

A comparative analysis of data redundancy and execution time between relational and object oriented schema table
… technique, which content entity relationship diagram and normalization. The relational technique is easy to use and useful for reducing data redundancy because the normalization technique solves the data redundancy by applying normalization normal forms on the schema tables. The second …

The Use of a BIM-Based Framework to Support Safe Facility Management Processes
… adds structure and relationships through a UML Class Diagram and Sequence Diagram. Additionally, standardized safety properties are developed for asset groups using the Asset Safety Identification Tool (ASIT). Finally, a conceptual graphical user interface (GUI) is developed to represent the …

Random generation of valid object configurations for testing object-oriented programs
… satisfy the multiplicity constraints in the UML class model of the program. Instead of discarding an invalid configuration, we attempt to fix it and generate a valid test case. Since we do not reject any test case, and do not depend on the feedback from previous test cases, our object …

Aesthetics and automatic layout of UML class diagrams
… layout method, which produces drawings of UML class diagrams according to the UML specification and issues of human computer interaction, e.g. readability. A unique set of aesthetic criteria is combined from four different disciplines involved in this topic. Based on these aethetic rules, a …

Investigation of the Progenitors and Outbursts of Classical and Recurrent Novae
Classical novae (CNe) are interacting binary systems whose outbursts are powered by a thermonuclear runaway in accreted material on the surface of a white dwarf (WD). The secondary stars in such systems fill their Roche lobe and material is transferred onto the WD primary star via an accretion …
