Database management system - Database management system A database management system (DBMS) is a computer program (or more typically, a suite of them) designed to manage a database, a large set of structured data, and run operations on the data requested by numerous users. Typical examples of DBMS use include accounting, human resources and customer support systems. Originally found only in large companies with the computer hardware needed to support large data sets, DBMSs have more recently emerged as a fairly standard part of any company back office. DBMS's contrast with the more general concept of a database applications in that they are designed as the "engine" of a multi-user system. In order to fill this role, DBMSs are typically built around a private multitasking kernel with built-in networking support..
Relational database management system - Relational database management system A relational database management system is a database management system that is based on the relational model as introduced by Edgar F. Codd. Strictly speaking it should also satisfy Codd's 12 rules but in practice there is no DBMS that satisfies all these rules. In fact, most successful DBMSs (and the query language SQL) that are considered to be relational violate the relational model in several important ways. However, most database practitioners and researchers use the term in a loose way such that most databases that support SQL are also included. The first released RDBMS that was a relatively faithful implementation of the relational model was the Multics Relational Data Store, first sold in 1978. Others have been Berkeley Ingres QUEL and IBM.
Document management system - Document management system A document management system is originally a computer program (or set of programs) used to track and store paper documents. Modern systems often also support storage and retrieval of electronic documents in the form of word processor files and the like. Table of contents showTocToggle("show","hide") 1 Physical Paper Document Management Systems 2 Electronic Document Management Systems 3 See Also 4 External Links: Physical Paper Document Management Systems Typical systems have the user scan in the original paper document, and store the image of the document in a database of some sort. The image is often given a name containing the date, and the user is often asked to type in additional "tags" in order to make finding the image easier. For instance, a user.
Bonsai CVS code management system - Bonsai CVS code management system The Bonsai CVS code management system is a computer program designed to help large programming projects productively manage CVS code archives. It was initially developed to fill the Mozilla project's need for good tools to allow multiple developers to edit its extremely large codebase. Among other features, Bonsai allows complex queries to be performed, as well as near real-time updates of checkins to the CVS server. Bonsai was founded by Terry Weissman. It was first written in TCL, then later ported to Perl. It still uses Perl, but runs off a MySQL database, and can be served using any Perl aware webserver, such as Apache..
Content management system - Content management system A content management system (CMS) is a system used to organize and facilitate collaborative content creation. CMSs allow end-users (typically authors of some sort) to provide new content in the form of articles. The articles are typically entered as plain text, perhaps with markup to indicate where other resources (such as pictures) should be placed. The system then uses rules to style the article, which separates the display from the content, which has a number of advantages when trying to get many articles to conform to a consistent "look and feel". The system then adds the articles to a larger collection for publishing. The systems also often include some sort of concept of the workflow for the target users, which defines how the new.
Distributed database - Distributed database In telecommunication, the term distributed database has the following meanings: 1. A database that is not entirely stored at a single physical location, but rather is dispersed over a network of interconnected computers. 2. A database that is under the control of a central database management system in which storage devices are not all attached to a common processor. Source: from Federal Standard 1037C.
Digital rights management - Digital rights management Digital rights management or digital restrictions management, commonly abbreviated DRM, is an umbrella term for any of several arrangements by which the usage of a copyrighted digital work can be restricted by the owner of the rights to the work. The actual arrangements are called technical protection measures (although the distinction between the two terms is not particularly clear). Although technical protection measures for software have been common since the 1980s, DRM is increasingly being used for creative works too. Some would like to use DRM mechanisms to protect other "proprietary information", particularly trade secrets and uncopyrightable facts in databases (see also database protection laws). In contrast to existing legal restrictions which copyrighted status imposes on the owner of a copy of any such data,.
Database - Database A database is an information set with a regular structure that allows automated searches and updates. There are a wide variety of databases, from simple tables stored in a single file to very large databases with many millions of records, stored in rooms full of disk drives. Databases resembling modern versions were first developed in the 1960s. A pioneer in the field was Charles Bachman. One way of classifying databases is by the programming model associated with the database. Several models have been in wide use for some time. Historically, the hierarchical model was implemented first, then the network model, then the relational model and flat models reached their zeniths. Database models The flat (or table) model consists of a single, two-dimensional array of data.
Database transaction - Database transaction A database transaction is a unit of interaction with a Database management system or similar system that is treated in a coherent and reliable way independent of other transactions. Ideally, a database system will guarantee all of the ACID properties for each transaction. In practice, these properties are often relaxed somewhat to provide better performance. In database products the ability to handle transactions allows the user to ensure that integrity of a database is maintained. A single transaction might require several queries, each reading and/or writing information in the database. When this happens it is usually important to be sure that the database is not left with only some of the queries carried out. For example, when doing a money transfer, if the money.
Database log - Database log In computer science, in the field of databases, a Database Log is a history of actions executed by a database management system. Physically, a log is a file of records stored in stable storage, designed to withstand crashes. Table of contents showTocToggle("show","hide") 1 Anatomy of a General Database Log 2 Types of Database Logs Records 3 Tables Anatomy of a General Database Log A database log record is made up of (FIXME: resource managers, xid not universal) Log Sequence Number: A unique id for a log record. With LSNs, logs can be recovered in constant time. Most logs' LSNs are assigned in monotonically increasing order, which is useful in recovery algorithms, like ARIES. Prev LSN: A link to the last log record. This implies.
Database administrator - Database administrator (Database Administrator) A person who is responsible for the environmental aspects of a database. In general, these include: Recoverability Integrity Security Availability Performance Development and testing support The duties of a database administrator at a particular site vary, depending on the policies in place and the database management system’s (DBMS’s) capabilities for carrying them out. Before going on, we need to briefly define and describe “database.” A database is a collection of related information, accessed and managed by its DBMS. After experimenting with hierarchical and networked DBMSs during the 1970’s , the IT industry became dominated by relational DBMSs such as Oracle Server. A relational DBMS manages information about types of real-world things (entities) in the form of tables that represent the entities. A.
Business System 12 - Business System 12 Business System 12, or simply BS12, was one of was the first fully relational database management systems, designed and implemented by IBM's UK Bureau Service subsidiary. Programming started in 1978 and the first version was delivered in 1982. It was never widely used and essentially disappeared soon after the division was shut down in 1985. BS12's lasting contribution to history was the use of a new query language, based onISBL, created at their UK Scientific Centre. Details of the engine were picked up from the famous System R underway in the US at the same time, but they decided to dispose with SQL and modify ISBL instead. BS12 included a number of interesting features that still have yet to appear on SQL-based systems, some.
Customer relationship management - Customer relationship management The stated purpose of customer relationship management (CRM) is to enable a company to better serve its customers through the introduction of reliable service automated processes, personal information gathering and processing, and self-service. It attempts to integrate and automate the various customer serving processes within a company. It typically involves three general areas of business. They are a customer service system, a marketing information system and a sales force management system. The marketing information part provides information about the business environment, including competitors, industry trends, and macroenviromental variables. The sales force management part automates some of the company's sales and sales force management functions. It keeps track of customer preferences, buying habits, and demographics, and also sales staff performance. The customer service part automates some.
Sequent Computer Systems - eventually they were purchased by IBM in 1999. Although the acquisition was made to establish NUMA-Q-based systems as the high end of their Intel-based platform line, changes in senior IBM management led to changes in strategy, and the death knell for NUMA-Q was sounded when in 2002, two layoffs at Sequent's former headquarters in Beaverton, Oregon ended all development on the systems for which IBM had acquired the company. History Sequent formed in 1983 when a group of eighteen engineers and executives left Intel after the failed iAPX 432 mainframe on a chip project was cancelled. They started Sequent to develop a line of SMP computers, then considered one of the up-and-coming fields in computer design. Sequent's first computer systems were the Balance 8000 and Balance 21000 released in 1984. The.
Relational database - Relational database A relational database is a database based on the relational model. Strictly speaking, this means a relational database takes the form of a specific collection of data. The database software that is used to manage the data is called a relational database management system, or RDBMS. (However, common usage doesn't always preserve this distinction.) Relational databases should be stored in normal form. See also Database management system (DBMS).
Object database - Object database An object database (more correctly referred to as ODBMS or OODBMS for Object Database Management System) is a DBMS that stores objects as opposed to rows/tuples in a RDBMS or relational database system. It is most often used in the case of C++ and Java programmers that do not wish to deal with the impedance mismatch of going from an OO language to a database query language like SQL programming language that RDBMS require. Developers prefer to be able to persist an object without having to go through a paradigm shift. Also missing from RDBMS is the concept of polymorphism, which is central to OO design, thus causing headaches when mapping from OO code to an RDBMS. Of course this has advantages and disadvantages. The.
Object-relational database - Object-relational database And Object-Relational database management systems (ORDBMS) are an evolutionary extension of relational DBMS products. The term is also sometimes used to describe external software products running over traditional DBMSs to provide similar features. These systems are more correctly referred to as object-relational mapping. Whereas RDBMS -- or SQL-DBMS -- products focused on the efficient management of data drawn from a limited set of data types (defined by the relevant language standards) an object-relational DBMS allows software developers to integrate their own types and the methods that apply to them into the DBMS. The goal of ORDBMS technology is to allow developers to raise the level of abstraction at which they view the problem domain. In an RDBMS, it would be fairly common to see SQL like.
Open Database Connectivity - Open Database Connectivity Open Database Connectivity or ODBC is a standard software API for connecting to database management systems. This API is independent of any one programming language, database system or operating system. ODBC is based on the Call Level Interface (CLI) specifications from SQL, X/Open Company (now known as The Open Group), and the ISO/IEC. ODBC was created by the SQL Access Group and first released in September, 1992. ODBC is a native interface that is accessed through a language that can make calls into a native library. In case of the Windows platform, this library is a DLL. Microsoft Windows was the first to provide an ODBC product. Now versions exist for UNIX, OS/2, and Macintosh platforms as well. In addition to the ODBC software,.

Jakarta Slide - Slide Slide is an open-source content management system from the Jakarta project. It is written in Java and implements the WebDAV protocol. Slide provides a hierarchical organization of storing data. Content is stored within a Domain which includes one or more Namespaces. Each namespace is identified by a Uniform Resource Identifier (URI). A namespace contains one or more Stores of information, e.g., a database or a directory tree. A Service is associated with each store and manages the connection to that store. A store contains one or more Scopes. Slide can be used with multiple data sources requiring only small abstraction layers to be written for each repository. Part of content management includes support for security, locking and versioning. The Slide engine is implemented as a JMX Managed Bean (MBean). WebDAV.
