| division operation in relational algebra: Relational Database Design and Implementation Jan L. Harrington, 2016-04-15 Relational Database Design and Implementation: Clearly Explained, Fourth Edition, provides the conceptual and practical information necessary to develop a database design and management scheme that ensures data accuracy and user satisfaction while optimizing performance. Database systems underlie the large majority of business information systems. Most of those in use today are based on the relational data model, a way of representing data and data relationships using only two-dimensional tables. This book covers relational database theory as well as providing a solid introduction to SQL, the international standard for the relational database data manipulation language. The book begins by reviewing basic concepts of databases and database design, then turns to creating, populating, and retrieving data using SQL. Topics such as the relational data model, normalization, data entities, and Codd's Rules (and why they are important) are covered clearly and concisely. In addition, the book looks at the impact of big data on relational databases and the option of using NoSQL databases for that purpose. - Features updated and expanded coverage of SQL and new material on big data, cloud computing, and object-relational databases - Presents design approaches that ensure data accuracy and consistency and help boost performance - Includes three case studies, each illustrating a different database design challenge - Reviews the basic concepts of databases and database design, then turns to creating, populating, and retrieving data using SQL |
| division operation in relational algebra: SQL and Relational Theory C. Date, 2011-12-16 SQL is full of difficulties and traps for the unwary. You can avoid them if you understand relational theory, but only if you know how to put the theory into practice. In this insightful book, author C.J. Date explains relational theory in depth, and demonstrates through numerous examples and exercises how you can apply it directly to your use of SQL. This second edition includes new material on recursive queries, “missing information” without nulls, new update operators, and topics such as aggregate operators, grouping and ungrouping, and view updating. If you have a modest-to-advanced background in SQL, you’ll learn how to deal with a host of common SQL dilemmas. Why is proper column naming so important? Nulls in your database are causing you to get wrong answers. Why? What can you do about it? Is it possible to write an SQL query to find employees who have never been in the same department for more than six months at a time? SQL supports “quantified comparisons,” but they’re better avoided. Why? How do you avoid them? Constraints are crucially important, but most SQL products don’t support them properly. What can you do to resolve this situation? Database theory and practice have evolved since the relational model was developed more than 40 years ago. SQL and Relational Theory draws on decades of research to present the most up-to-date treatment of SQL available. C.J. Date has a stature that is unique within the database industry. A prolific writer well known for the bestselling textbook An Introduction to Database Systems (Addison-Wesley), he has an exceptionally clear style when writing about complex principles and theory. |

| division operation in relational algebra: Interfaces to Database Systems (IDS92) Richard Cooper, 2012-12-06 Despite the volume of research carried out into the design of database systems and the design of user interfaces, there is little cross-fertilization between the two areas. The control of user interfaces to database systems is, therefore, significantly less advanced than other aspects of DBMS design. As database functionality is used in a wider range of areas, such as design applications, the suitability of the user interface is becoming increasingly important. It is, therefore, necessary to begin applying the knowledge developed by HCI researchers to the specialised domain of database systems. This volume contains revised papers from the International Workshop on Interfaces to Database Systems, held in Glasgow, 1-3 July 1992. The workshop aimed to develop an interaction between the design of database systems and user interfaces. It discussed both the production of interfaces tailored to particular applications, and also more general systems within which interfaces can be developed. Some of the papers concentrate on usability aspects, some discuss different interface metaphors, whilst others tackle the question of designing a general conceptual model. The latter topic is of particular importance, as it is only by achieving an abstract model of what the user understands to be in the database that the data can be associated with appropriate interface facilities. Among the contents of the volume are: integrated interfaces to publicly available databases; database query interface for medical information systems; an integrated approach to task oriented database retrieval interfaces; GRADI: a graphical database interface for a multimedia DBMS; cognitive view mechanism for multimedia information systems; a graphical schema representation for object oriented databases; a conceptual framework for error analysis in SQL interfaces; a browser for a version entity relationship database. Interfaces to Database Systems (IDS92) is unique in that it brings together a variety of approaches from the database and HCI research communities. It will provide essential reading for researchers of database systems and also industrial developers of DBMS. |

| division operation in relational algebra: Information Modeling and Relational Databases T. A. Halpin, 2001 Information Modeling and Relational Databases provides an introduction to ORM (Object Role Modeling)-and much more. In fact, it's the only book to go beyond introductory coverage and provide all of the in-depth instruction you need to transform knowledge from domain experts into a sound database design. Inside, ORM authority Terry Halpin blends conceptual information with practical instruction that will let you begin using ORM effectively as soon as possible. Supported by examples, exercises, and useful background information, his step-by-step approach teaches you to develop a natural-language-based ORM model and then, where needed, abstract ER and UML models from it. This book will quickly make you proficient in the modeling technique that is proving vital to the development of accurate and efficient databases that best meet real business objectives. * The most in-depth coverage of Object Role Modeling available anywhere-written by a pioneer in the development of ORM. * Provides additional coverage of Entity Relationship (ER) modeling and the Unified Modeling Language-all from an ORM perspective. * Intended for anyone with a stake in the accuracy and efficacy of databases: systems analysts, information modelers, database designers and administrators, instructors, managers, and programmers. * Explains and illustrates required concepts from mathematics and set theory. * Via a companion Web site, provides answers to exercises, appendices covering the history of computer generations, subtype matrices, and advanced SQL queries, and links to downloadable ORM tools. |
