Database management systems

hundreds, perhaps more than a thousand heterogeneous databases are currently operating. Some divisions have standardized the database technology on Oracle, while others are using a combination of Sybase, MySQL, SQL Server, etc. These Relational Database Management Systems (RDBMSs), supporting many databases and applications and each hosted on dedicated servers, are often under-utilizing the server resources available to them. Such a database infrastructure, therefore, is not cost-, or resource-effective

A relational database management system is based on the relational model described by E.F. Codd. Data is stored in tables, in the form of rows and columns and the relationhips between these tables is also stored in the form of a table. The tables, which contain data stored in rows and columns are made using SQL. Before storing data, it is essential to identify relationships among them. This is done so using an Entity-Relationship diagram which is a graphical representation that identifies relationships

Generated information include predominant information and it will have to be analyzed for gathering essential expertise. On the whole, relational databases are used so as to system the data. These, ways works successfully for small amount of knowledge. What if the data is very tremendous? To avoid this problems Mongo databases are introduced. MongoDB is a cross-platform document-oriented database. Classified
