Largest Databases in the World
A database is an organized collection of data. The data are typically organized to model relevant aspects of reality in a way that supports processes requiring this information. For example, modelling the availability of rooms in hotels in a way that supports finding a hotel with vacancies.
Database management systems (DBMSs) are specially designed software applications that interact with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is a software system designed to allow the definition, creation, querying, update,
and administration of databases. Well-known DBMSs include MySQL, MariaDB, PostgreSQL, SQLite, Microsoft SQL Server, Oracle, SAP HANA, dBASE, FoxPro, IBM DB2, LibreOffice Base, FileMaker Pro and InterSystems Caché. A database is not generally portable across different DBMSs, but different DBMSs can interoperate by using standards such as SQL and ODBC or JDBC to allow a single application to work with more than one database.
1. The World Data Centre for Climate:
" The ICSU World Data System (WDS) was created by the 29th General Assembly of the International Council for Science (ICSU) and builds on the 50-year legacy of the former ICSU World Data Centres (WDCs) and former Federation of Astronomical and Geophysical data-analysis Services (FAGS).
WDS strives to form a worldwide ‘community of excellence’ for multidisciplinary scientific data, which ensures the long-term stewardship and provision of quality-assessed data and data services to the international science community and other stakeholders. Its concept aims at a transition from existing stand-alone components and services to a common globally interoperable distributed data system, with searchable common data directories and catalogues that incorporates emerging technologies and new scientific data activities. Disciplinary and multidisciplinary data networks within WDS will play a key role in moving this concept forward."
2. National Energy Research Scientific computing Center:
NERSC is known as one of the best-run scientific computing facilities in the world. It provides some of the largest computing and storage systems available anywhere, but what distinguishes the center is its success in creating an environment that makes these resources effective for scientific research. NERSC systems are reliable and secure, and provide a state-of-the-art scientific development environment with the tools needed by the diverse community of NERSC users. NERSC offers scientists intellectual services that empower them to be more effective researchers. For example, many of our consultants are themselves domain scientists in areas such as material sciences, physics, chemistry and astronomy, well-equipped to help researchers apply computational resources to specialized science problems.
