دانلود کتاب Database Development For Dummies

Database Development For Dummies is a "prequel" to SQL for Dummies, which is used in many college database courses across the country. Database Development For Dummies tells why and how database systems came into being, then using actual examples, describes the many obstacles to success that frequently arise in database development projects, and how to handle them. The key to successful database development is accurate and appropriate modeling of the real-world system that will be placed on the computer. Database Development For Dummies describes in detail two popular modeling methods, the entity-relationship model and the semantic object model. Once the model of a system is complete, the book describes how to convert the model into a database design, then implement the model on the target platform. Database on intranets and the Internet is covered, as are the issues that arise when multiple users simultaneously access the same database. A chapter is devoted to the emerging enterprise database market, including data warehousing. Another chapter covers the new object-relational technology.
