Determine the Object oriented principles

Many latest applications are being developed based on object oriented principles such as methods, classes, and inheritance. To fulfil the requirements of such developments, CASE tools provide many benefits to developers building large-scale systems. This tools enable us to abstract away from the mess of source code, to a stage where propose and design become easier and clearer to understand and modify.  For representing and making these properties of the systems to be developed, some tools are used. These tools support both UML features and building blocks. These CASE tools provide support for object oriented modelling methodologies and notations, and also generate parts of object oriented applications.  Many object oriented CASE tools newer versions are beginning to address new languages such as Java. These tools also support relational databases by performing arts of logic, and in some of the cases, physical database design and modelling, including reverse engineering of RDBMS tables and schema generation, and other elements.  Here, we have tried to give you a list collected from individual searches and many sites, for UML modelling tools. Since it is a fast growing engineering this list may keep changing continuously with time
