In data modeling, initially, a conceptual data model is created which is later translated to the physical data model.UML(Unified Modeling Language)This was all about Software Engineering.Given the cost and importance of removing errors improvements in fault detection and removal can be of significant benefit.

Data Modeling The process of structuring and organizing data is known as Data Modeling.

External quality is dependent on the internal in the sense that software works in the real-world environment with respect to the code written by the coder.
Software Testing After the software product is implemented, it goes through the testing phase to find any underlying error or bug.
SDLCSDLC or Software Development Lifecycle is a set of stages followed for the development of a software product.
For building a software product steps are followed beginning from data collection to software maintenance.
Software Quality Software Quality refers to the study of software features both external and internal taking into consideration certain attributes.
External features mean how software is performing in a real-world environment while internal features refer to the quality of code written for the software.
