Object databases have been considered since the early 1980s and 1990s but they have do little impact on mainstream commercial data processing, though at that place is some employment in specialized areas.When database capabilities are combined with object-oriented (OO) programming language capabilities, the result is an object database management system (ODBMS).Todays trend in programming languages is to utilize objects, at that placeby do OODBMS ideal for OO programmers because they can develop the product, chisel in them as objects, and can replicate or modify animate objects to make new objects within the OODBMS. Information today includes not only if data but video, audio, graphs, and photos which are considered complex data types. Relational DBMS arent natively capable of supporting these complex data types. By being integrated with the programming language, the programmer can maintain consistency within iodin environment because both the OODBMS and the programming language will use the kindred model of representation. Relational DBMS projects using complex data types would have to be divided into two separate tasks the database model and the application.As the usage of web-based technology increases with the implementation of Intranets and extranets, companies have a vested interest in OODBMS to ostentation their complex data. Using a DBMS that has been specifically designed to store data as objects gives an advantage to those companies that are geared towards multimedia presentation or orga nizations that utilize computer-aided design (CAD).Some object-oriented databases are designed to take a shit well with object-oriented programming languages much(prenominal) as Python, Perl, Java, C, Visual Basic .NET, C++, Objective-C and Smalltalk others have their own programming languages. ODBMSs use exactly the aforesaid(prenominal) model as object-oriented programming languages.AdvantagesThe main benefit of creating a database with objects as data is speed.OODBMS are faster than relational DBMS because data isnt stored in relational rows and columns but as objects.Objects have a m whatsoever to many relationship and are regained by the use of pointers.Pointers are linked to objects to corroborate relationships.Another benefit of OODBMS is that it can be programmed with small procedural differences without alter the entire system.This is most helpful for those organizations that have data relationships that arent entirely travel by or strike to change these relations t o satisfy the new melodic line requirements.This ability to change relationships leads to another benefit which is that relational DBMS buzzword handle complex data models while OODBMS can.DisadvantagesSlower and more concentrated to formulate than relational.Lack of interoperability with a great number of tools/features that are interpreted for granted in the SQL world, including but not limited to industry standard connectivity, reporting tools, OLAP tools, and backup and recovery standards.Lack a formal mathematical foundation, unlike the relational model, and this in turn leads to weaknesses in their query support.ApplicationsObject databases based on persistent programming acquired a niche in application areas such as engineering and spatial databases, telecommunications, and scientific areas such as high energy physics and molecular biology. They have make little impact on mainstream commercial data processing, though there is some usage in specialized areas of financial s ervices.67 It is also cost noting that object databases held the record for the Worlds largest database (being the first to hold over 1000 terabytes at Stanford Linear Accelerator Center)8 and the highest ingest rate ever recorded for a commercial database at over one Terabyte per hour.Another aggroup of object databases focuses on embedded use in devices, packaged bundle, and real time systems.http//shine.yahoo.com/channel/none/oodbms-object-oriented-database-management-system-basics-533483//**************************************Observations from a Tech Architect Enterprise instruction execution Issues Solutionsby Craig Borysowich(Chief Technology Tactician)Enterprise Technology Architect Craig Borysowich shares the challenges and achievements of enterprise source design and moreEnterprise Technology Architect Craig Borysowich shares the challenges and achievements of enterprise resolving power design and implementation. ..lessBlog Main/ Archive/ Invite PeersRSSRSS for Posts / RSS for CommentsPrevious entry / Next EntrySome Pros Cons of Relational DatabasesCraig Borysowich(Chief Technology Tactician)posted5/1/2008 Comments(0)http//images.ittoolbox.com/vt/icons/thumbsup.pngLike (0)Please Sign In or Register to like this blog.WorkingShareShareThe relational model for databases provides the basic DBMS characteristics. In addition, an RDBMS also conforms to Codds model.Relational Database CharacteristicsDr. Codd established 12 rules to which a DBMS must conform to be considered relational. DBMSs vary in the way in which they comply with these rules, however, commercial relational databases generally conform to these rules.Strengths of RDBMSFlexible and well-established. undecomposed theoretical foundation and use over many years has resulted in stable, standardized products available.Standard data glide slope language through SQL. be and risks associated with large development efforts and with large databases are well understood.The fundamental structur e, i.e., a table, is easily understood and the design and normalization process is well defined.Weaknesses of RDBMSPerformance problems associated with re-assembling simple data structures into their more complicated real-world representations.Lack of support for complex base types, e.g., gulps.SQL is limited when assentinging complex data.Knowledge of the database structure is required to spend a penny ad hoc queries.Locking mechanisms defined by RDBMSs do not let design transactions to be supported, e.g., the check in and check out type of feature that would allow an engineer to modify a drawing over the course of several working days.http//it.toolbox.com/blogs/enterprise-solutions/some-pros-cons-of-relational-databases-24144/*******************************The Advantages of a Relational Database Management Systemds_0ecbc811-e864-4fed-a7c6-5a46ff28cd3fContributorBy Deborah Lee Soltesz, eHow Contributing WriterArticle judge (0 Ratings)EmailFacebookTwitterStumbleUponAdd to Favo ritesPrintShareI destiny to do this Whats This?RDBMSs provide user access control and data impartiality features.data security image by dinostock from Fotolia.comRDBMSs provide user access control and data integrity features.A Relational Database Management System (RDBMS) is a software system that provides access to a relational database. The software system is a collection of software applications that can be used to create, maintain, manage and use the database. A relational database is a database structured on the relational model. Data are stored and presented in a tabular format, organize in rows and columns with one record per row.Data StructureThe table format is simple and easy for database users to understand and use. RDBMSs provide data access using a natural structure and organization of the data. Database queries can search any column for matching entries.Multi-User AccessRDBMSs allow multiple database users to access a database simultaneously. Built-in locking and tr ansactions management functionality allow users to access data as it is being changed, prevents collisions between two users updating the data, and keeps users from accessing partially updated records.Privileges permission and privilege control features in an RDBMS allow the database administrator to restrict access to authorized users, and grant privileges to individual users based on the types of database tasks they need to perform. federal agency can be defined based on the remote thickening IP address in combination with user authorization, restricting access to specific external computer systems.Network AccessRDBMSs provide access to the database through a server daemon, a specialized software program that listens for requests on a network, and allows database clients to connect to and use the database. Users do not need to be able to log in to the physical computer system to use the database, providing convenience for the users and a layer of security for the database. Netwo rk access allows developers to build desktop tools and Web applications to interact with databases.SpeedThe relational database model is not the fastest data structure. RDBMS advantages, such as simplicity, make the bumper-to-bumper speed a fair trade-off. Optimizations built into an RDBMS, and the design of the databases, enhance performance, allowing RDBMSs to perform more than fast enough for most applications and data sets. Improvements in technology, change magnitude processor speeds and decreasing memory and storage costs allow systems administrators to build incredibly fast systems that can overcome any database performance shortcomings. alimonyRDBMSs feature maintenance utilities that provide database administrators with tools to easily maintain, test, repair and back up the databases housed in the system. Many of the functions can be automated using integrate automation in the RDBMS, or automation tools available on the operational system.LanguageRDBMSs support a generi c language called Structured interview Language (SQL). The SQL syntax is simple, and the language uses standard English language keywords and phrasing, making it fairly intuitive and easy to learn. Many RDBMSs add non-SQL, database-specific keywords, functions and features to the SQL language.
