SQL Developer Data Modeler: a Top-Down Product Overview
SQL Developer Data Modeler: A Top-Down Product Overview Sue Harper Oracle United Kingdom Keywords: SQL Developer Data Modeler, ERD, DDL Generation, model, capture, design Introduction Oracle SQL Developer Data Modeler is a graphical data modeling tool for creating, browsing and editing data models, including logical, relational, physical, multi-dimensional, and data type models. It supports forward and reverse engineering from Oracle Database, Microsoft SQL Server and IBM DB2 databases and the generation of DDL scripts for these databases. SQL Developer Data Modeler offers features and utilities that enhance the data modeling experience, improve productivity and promote the use of standards. SQL Developer Data Modeler is designed for a broad spectrum of database developers; from business architects to DBAs and from database to application developers, serving as a powerful communication tool between developers and business users. In this article we review the main modelers and features in SQL Developer Data Modeler 2.0 starting with the logical model and progressing through the features to the final DDL script. Often called the top-down approach, this is not the only flow of work through the product, as indeed, users can start by importing a data model and reverse engineering the objects to create an initial diagram and progressing from there. We will refer to various methods of creating models and updating the database using the product. Integrated Models SQL Developer Data Modeler provides facilities to build sets of related and integrated models. Many consider the core of SQL Developer Data Modeler to be the logical model. It is this logical model that provides a true implementation-independent view of enterprise information. -

25 Object-Database Systems
25 OBJECT-DATABASESYSTEMS with Joseph M. Hellerstein U. C. Berkeley You know my methods, Watson. Apply them. —Arthur Conan Doyle, The Memoirs of Sherlock Holmes Relational database systems support a small, fixed collection of data types (e.g., in- tegers, dates, strings), which has proven adequate for traditional application domains such as administrative data processing. In many application domains, however, much more complex kinds of data must be handled. Typically this complex data has been stored in OS file systems or specialized data structures, rather than in a DBMS. Ex- amples of domains with complex data include computer-aided design and modeling (CAD/CAM), multimedia repositories, and document management. As the amount of data grows, the many features offered by a DBMS—for example, reduced application development time, concurrency control and recovery, indexing support, and query capabilities—become increasingly attractive and, ultimately, nec- essary. In order to support such applications, a DBMS must support complex data types. Object-oriented concepts have strongly influenced efforts to enhance database support for complex data and have led to the development of object-database systems, which we discuss in this chapter. Object-database systems have developed along two distinct paths: Object-oriented database systems: Object-oriented database systems are proposed as an alternative to relational systems and are aimed at application domains where complex objects play a central role. The approach is heavily in- fluenced by object-oriented programming languages and can be understood as an attempt to add DBMS functionality to a programming language environment. Object-relational database systems: Object-relational database systems can be thought of as an attempt to extend relational database systems with the func- tionality necessary to support a broader class of applications and, in many ways, provide a bridge between the relational and object-oriented paradigms. -

ISG STAFF WORKING PAPERS Objects in the Database
soG ISG STAFF WORKING PAPERS Public Disclosure Authorized Public Disclosure Authorized Public Disclosure Authorized Objects in the Database: A Reality Check Parvez Bashir Information Public Disclosure Authorized Officer, ISGEC IFl - I Sol Grion ISG STAFF WORKING PAPERS ISG Staff Working Papers are reviewed by the VP-CIO and by the ISG Senior Management Team. Papers are evaluated and the best of the papers will be recognized. The series is envisioned to be forward-looking and cover a broad range of topics. Over a period of time, the papers will be compiled and published as a book. ffMy= .I Parvez Bashir Information Officer, ISGEC Objects in the Database: A Reality Check The RDBMS (Relational Database Management System) ruled the database roost in the 1980s and 00 (Object Oriented) programming languages revolutionized software development in the 1990s. RDBMSs and 00 programming languages have complementary strengths. Relational database systems are good for managing large amounts of data; object oriented programming languages are good at expressing complex relationships among objects. Relational database systems are good for data retrieval but provide little support for data manipulation; object oriented programming languages are excellent at data manipulation but provide little or no support for data persistence and retrieval. These complementary strengths have given birth to a new breed of database management systems popularly known as Object Relational Database Management Systems (ORDBMS). The other database model which deals purely with objects is the ODBMS (Object Database Management System). ODBMSs pre-date the object relational model and have been in use since time immemorial in niche applications including multimedia. -
