Relational Database Management Systems IBM's DB2 or Oracle 9i? (Network Products).Butler Group has launched `Database Management Systems--Managing Relational and XML XML in full Extensible Markup Language. Markup language developed to be a simplified and more structural version of SGML. It incorporates features of HTML (e.g., hypertext linking), but is designed to overcome some of HTML's limitations. Data Structures'. This Technology Evaluation and Comparison Report reveals the new challenges that organisations face today such as: the need to store persisted XML, the need to decouple data management from database management and the need to choose the best solution based on specific data structures. Relational database management systems See DBMS for a shorter list of “typical”, representative database management systems. Open-source software
RDBMS - relational database ) form the foundations of business across the globe. Detailed technical reviews and comparisons of IBM's DB2, Oracle 9i and Microsoft' SQL Server An earlier relational DBMS from Sybase and from Microsoft. Sybase introduced SQL Server in 1988 for various Unix versions. In that same year, with help from IBM, Sybase created an OS/2 version that Microsoft licensed and branded as Microsoft SQL Server. are included in this Report. Between them, these three vendors control over 80% of the market, but the other players have not been ignored. Equally detailed reviews and comparisons are included for: Computer Associate's Advantage Ingres, Progress, Sybase ASE (Adaptive Server Enterprise) A relational DBMS from Sybase that runs on Windows NT/2000, Linux and a variety of Unix platforms. ASE is a comprehensive and robust data management product with a long history dating back to the late 1980s. and Virtuoso from Openlink. The Report also has detailed technical reviews of the two market leaders in the native-XML database arena: Software AG's Tamino and XIS from eXcelon. The Report contains: A comparative analysis of the leading vendors- The technology features needed to build a hierarchical and relational data infrastructure-Models and architectures that can be implemented-A review of the correct type of database management system to use for different structures-Details of bi-directional mapping techniques between relational and XML structures -Information on the abstractions required for effective data modelling-How top relational vendors are answering the challenges posed by XML data structures to enhance their products. The role that native XML databases will play-The importance of security and data encryption data encryption, the process of scrambling stored or transmitted information so that it is unintelligible until it is unscrambled by the intended recipient. Historically, data encryption has been used primarily to protect diplomatic and military secrets from foreign issues Comment The two 800lb gorillas in the enterprise level market are IBM's DB2 and Oracle 9i Using Buffer Group's objective scoring methodology, the report reveals which of these two really deserves to rule the roost. It also raises the question is one of those really `king', or does one of the `smaller' players have a better solution?" The Report also goes beyond the technical detail of database management systems, to consider the role that they play in total Information Asset Management (IAM IAM - Interactive Algebraic Manipulation. Interactive symbolic mathematics for PDP-10. ["IAM, A System for Interactive Algebraic Manipulation", C. Christensen et al, Proc Second Symp Symb Alg Manip, ACM Mar 1971]. ) environment. How both the old and the new models need to be designed to answer the needs of an extended data infrastructure. www.butlergroup.com |
