There are lots of sites on the Internet, Movie Database, Monster.com, Amazon.com etc who offer ways to search, sort, and view massive amounts of data.

Each of these sites work on a relational database. Since these sites have to handle a tremendous number of hits, they use big, expensive RDBMSes (Relational Database Management System). The names for the RDBMSes they user is familiar to anyone who follows the Nasdaq: Oracle, Sybase, Microsoft SQL Server, and Informix. These are pretty high end and huge databases. The use of content management systems to allow website owners to maintain their own websites also requires the technology of relational databases.

What is a Database?

In database parlance, the phone book is a table which contains a record for each subscriber. Each subscriber record contains three fields: Name, Address, and Phone number. The records are sorted alphabetically by the name fields, which is called the key fields.

Database Programs:

To create and maintain a computer database, you need a database program, often called a database management system, or DBMS. Just as databases programs, too, range in complexity.

Other database programs, called relational database programs or RDBMS, are designed to handle multi-file databases. FileMaker Pro is a relational database that’s easy to use and fairly inexpensive.

Database program tools:

A database program gives you the tools to:

  • Design the structure of your database.
  • Create data entry forms so you can get information into the database.
  • Validate the data entered and check for inconsistencies.
  • Sort and manipulate the data in the database.
  • Query the database (that is, ask questions about the data).

Using a database:

If mentions of programming languages make you feel you’re getting out of your depth, don’t worry! Most of the database programs you’re likely to encounter can be used at a variety of levels.

Over recent decades vast amounts of biological data have been accumulated. However, it is becoming increasingly difficult to apply traditional theoretical methods to the formulation of coherent pictures of cell and organ function because it is no longer possible for a human theorist to integrate all of the available information. Instead, computer technologies must now be used to perform this integration. This book brings together contributions from many different fields to summarize the current status of computer-assisted modelling of biological processes.The initial chapters deal with fundamental developments in hardware, software and mathematics that underlie current approaches to biological modelling. Next, different approaches to collating data on gene structure and function are presented. These databases form a vital resource for any investigator trying to construct an integrated picture of particular biological systems.Cell signalling systems form a particularly complicated aspect of all cellular function and are important both in the understanding of basic cellular processes and in selecting targets for drugs. Recent approaches to integrating data on cell signalling into computer models are covered. Further chapters build on these approaches to show how computerized models of intact cells can be developed. Finally, approaches to the computer modelling of whole organs such as the heart are presented. The role of computer modelling in drug design is the subject of the final chapter and is also touched on throughout the discussions.

The database industry is a multi-billion, world-wide, all-encompassing part of the software world. Quantifiers in Action: Generalized Quantification in Query, Logical and Natural Languages introduces a query language called GQs—Generalized Quantification in Query. Most query languages are simply versions of First Order Logic (FOL). GQs are an extension of the idea of quantifier in FOL. GQs are a perfect example of a practical theory within databases.This book provides a brief background in logic and introduces the concept of GQs, and then develops a query language based on GQs. Using Query Language with Generalized Quantifiers, the reader explores the efficient implementation of the concept, always a primary consideration in databases. This professional book also includes several extensions for use with documents employing question and answer techniques.Designed for practitioners and researchers within the database management field; also suitable for advanced-level students in computer science.

This volume contains the papers presented at the 10th International Conference on Automated Deduction (CADE-10). CADE is the major forum at which research on all aspects of automated deduction is presented. Although automated deduction research is also presented at more general artificial intelligence conferences, the CADE conferences have no peer in the concentration and quality of their contributions to this topic. The papers included range from theory to implementation and experimentation, from propositional to higher-order calculi and nonclassical logics; they refine and use a wealth of methods including resolution, paramodulation, rewriting, completion, unification and induction; and they work with a variety of applications including program verification, logic programming, deductive databases, and theorem proving in many domains. The volume also contains abstracts of 20 implementations of automated deduction systems. The authors of about half the papers are from the United States, many are from Western Europe, and many too are from the rest of the world. The proceedings of the 5th, 6th, 7th, 8th and 9th CADE conferences are published as Volumes 87, 138, 170, 230, 310 in the series Lecture Notes in Computer Science.
