In the modern database environment, new non-traditional database types appear that are Not SQL database (NoSQL). This NoSQL database does not rely on the principles of the relational database. Couchdb is one of the NoSQL Document-Oriented databases, in Couchdb the basic element was a document. All types of databases have the same conceptual data model and it was deferent in the logical and physical model, this mean UML class diagram can be used in the  NoSQL design at a conceptual level, that is, it can be used to design a Couchdb database. In this research, we suggest a method to model and implement the conceptual level of the Couchdb database from the UML class diagram in using simple way depending on the association types. Depending on the types of relationships between classes, we can have more than one database model to choose from and find the most suitable for the system to be designed. A medical clinic database was proposed to implement the transfer steps according to the proposed method. Three database models were designed and implemented to study the suitability of the proposed transfer method.

This research aims to provide a practical work on the principle of the Extreme Programming (XP) which is a type of the Agile Software Development Methods which is used in the generation of test-cases using the design information.  The resources utilized in the design information presented here are the design diagrams generated using the Unified Modeling Language (UML), as they are considered to be the most commonly used modeling language in these days, and also the newest. These UML diagrams are used to automatically develop a set of high quality test cases which are then used to test the system’s code after being written.
The main idea of this work is based on reducing the effort of the testing stage which costs more than 50% of the resources allocated for the whole development process; this cost may include the financial cost, the cost of the resources allocated for the project, and the timeline of the project.
In this work, enhancements have been made to the concept of Gene Expression Programming to ensure the generation of high quality the test cases that are generated automatically, and a solution has been presented for the parallel paths and the loop paths problems that are found in the design.
