Week 11 database..
Finally I have reached at the end of this semester so this lesson is the last lesson. It’s about database and basically I learnt the basic usage of MS Access. Before access our lecture gave us some explanation about the database. A database is a collection of information that is organized so that it can easily be accessed, managed, and updated. In one view, databases can be classified according to types of content: bibliographic, full-text, numeric, and images. A database management system (DBMS) is a software package with computer programs that control the creation, maintenance, and use of a database. It allows organizations to conveniently develop databases for various applications by database administrators (DBAs) and other specialists. Types of Database Models: The hierarchical database is based on the hierarchical data model but with records. The model resembles an upside down tree. The hierarchical database is viewed as a Parent/ Child relationship using ‘one-to-many’ relationships, The Network database was developed to improve short comings of the hierarchical database. The network database differed in a couple of ways. The network database uses one-to-many relationships, The relational database emerged around the 1970’s and is still a leading technology for database management, The object orientated database, models the elements as objects, which is similar to object programming. By designing object databases with the same language. So that is some information about database. In the class I also access the Microsoft access database that never use before. So for this semester I have learnt many things that are new approach for me. Lastly I would like to say thank you too much to my lecture for giving me the knowledge………………………..
