    Data in a network database is organized in many-to-many relationships. The network database structure was invented by Charles Bachman. Relational Databases In relational database management systems RDBMS , the relationship between data is relational and data is stored in tabular form of columns and rows. Each column if a table represents an attribute and each row in a table represents a record.

    Each field in a table represents a data value. Relational databases work on each table has a key field that uniquely indicates each row, and that these key fields can be used to connect one table of data to another.

    Relational databases are the most popular and widely used databases. The relational database has two major reasons Relational databases can be used with little or no training. Database entries can be modified without specify the entire body. Properties of Relational Tables In the relational database we have to follow some properties which are given below.

    Column Values are of the Same thing. Columns is undistinguished. Sequence of Rows is Insignificant. Each Column has a common Name.

    RDBMs are the most popular databases. Object-Oriented Model In this Model we have to discuss the functionality of the object oriented Programming.

    It takes more than storage of programming language objects. I t provides full-featured database programming capability, while containing native language compatibility.

    It adds the database functionality to object programming languages. This approach is the analogical of the application and database development into a constant data model and language environment.

    It is a package designed to define, manipulate, and manage data in a database. Some general functions of a DBMS: Designed to allow the definition, creation, querying, update, and administration of databases Define rules to validate the data and relieve users of framing programs for data maintenance Convert an existing database, or archive a large and growing one Run business applications, which perform the tasks of managing business processes, interacting with end-users and other applications, to capture and analyze data Some well-known DBMSs are Microsoft SQL Server, Microsoft Access, Oracle, SAP, and others.

    Below is a list of components within the database and its environment. Software This is the set of programs used to control and manage the overall database. This includes the DBMS software itself, the Operating System, the network software being used to share the data among users, and the application programs used to access data in the DBMS. Data DBMS exists to collect, store, process and access data, the most important component. The database contains both the actual or operational data and the metadata.

    Procedures These are the instructions and rules that assist on how to use the DBMS, and in designing and running the database, using documented procedures, to guide the users that operate and manage it. Appendix B provides a second case study based on a veterinary clinic called PerfectPets, which we use in the Exercises at the end of many chapters.

    Appendix D provides a summary of the methodology as a Prelims-4 5 quick reference guide. Appendices F and G provide guidelines for choosing index and when to consider denormalization to help with Step 4.

    Appendix H provides an introduction to the main object-oriented concepts for those readers who are unfamiliar with them. Finally, Appendix I provides a set of 15 common data models. The logical organization of the book and the suggested paths through it are illustrated in Figure P. Prelims-5 6 Pedagogy To make the book as readable as possible, we have adopted the following style and structure: A set of objectives for each chapter, clearly highlighted at the start of the chapter.

    A summary at the end of each chapter covering the main points introduced. Review Questions and Exercises at the end of most chapters. Each important concept that is introduced is clearly defined and highlighted by placing the definition in a box. A series of notes and tips you will see these throughout the book with an adjacent icon to highlight them. Diagrams are liberally used throughout to support and clarify concepts. A very practical orientation.

    Each chapter contains many worked examples to illustrate the points covered. A Glossary at the end of the book, which you may find useful as a quick reference guide. Business schools that are or aspire to be accredited by the Association to Advance Collegiate Schools of Business AACSB can make immediate use of the chapter objectives to form clear and concise learning objectives mandated by the AACSB re-accreditation requirements.

Additional case studies and assignments A large range of case studies and assignments that can be used to supplement the Exercises at the end of each chapter, with solutions.

    An SQL script for each common data model defined in Appendix I to create the corresponding set of base tables for the database system. Once again, these scripts can be used to create a database in many relational DBMSs.
