(PDF) Database Management: Concepts and Design | Bhojaraju Gunjal - rumahhijabaqila.comRelational database systems underpin the majority of the managed data storage in computer systems. This course presents an overview of the development life cycle for a database system and highlights how the database development differs from traditional software development. In this course we look at an outline of the stages involved in the development of a database. We consider the broader issue of how to decide what should be in a database and how to structure the tables that should be included. Our aim is to give you a basic development method so that you can see how a basic database system is developed. We don't argue that this specific method is the most applicable to any given situation — however, we do consider that this method is straightforward and will allow you to contextualise or, by comparison, consider a range of database development techniques.
Chapter 13 Database Development Process
A core aspect of software engineering is the subdivision of the development process into a series of phases, or steps, each of which focuses on one aspect of the development. The software product moves through this life cycle sometimes repeatedly as it is refined or redeveloped until it is finally retired from use. Ideally, each phase in the life cycle can be checked for correctness before moving on to the next phase. Let us start with an overview of the waterfall model such as you will find in most software engineering textbooks. This waterfall figure, seen in Figure It shows the process as a strict sequence of steps where the output of one step is the input to the next and all of one step has to be completed before moving onto the next.
In this chapter, SQL, a commonly used database development tool, will be introduced. You will ◾ Cloud Database Development and Management.

Introduction to DBMS
A database is an organized collection of data , generally stored and accessed electronically from a computer system. Where databases are more complex they are often developed using formal design and modeling techniques. The database management system DBMS is the software that interacts with end users , applications, and the database itself to capture and analyze the data. The DBMS software additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a "database system". Often the term "database" is also used to loosely refer to any of the DBMS, the database system or an application associated with the database. Computer scientists may classify database-management systems according to the database models that they support.
