ENTERPRISE DATABASE SYSTEMS Enterprise software- A suite of applications generally used by a large nos. of users and which handles millions of records. Distributed application – An application which is divided into parts that reside and executes on different PCseven if those are in separate locations is called distributed application. The word tire is used to describe distributed applications. Two tier application- If the job of managing a database is between two PCs, then the application is two tier application. Similarly three tier to n-tier applications. Electronic Document Management (EDM) – An enterprise software used in various large scale multiuser environment likefactories, hospitals etc. Connected architecture: In connected model we can connect any application to database and stays connected to the database system even when it is not using any database operations. For this architecture, we use Connection, Command and DataReader. Disconnected architecture: In disconnected model we connect any application to database until we call the close method. In this architecture we use DataSet and DataAdapter Knowledge Discovery - Knowledge discovery is the science of finding patterns within sets of data. This data can consist of anything from boolean values (did he go left? did he go right?), sports scores, web visit statistics, laboratory analyses, or other scientific measurement. By itself data is simply measurement transformed into numbers and statistics, but inherent in the data is a lot of knowledge that can be put to good use. Also known as data mining, knowledge discovery has enjoyed great success in many lucrative fields, including:      

Government surveillance Customer relationship management Digital mapping Medical risk assessment Market analysis Educational research

Depending on how large the data field is, knowledge discovery can require an automated program or not. The largest data field out there in this day and age, and certainly the most mineable for knowledge is the Internet. Data Mining - Data Mining is an analytic process designed to explore data (usually large amounts of data typically business or market related - also known as "big data") in search of consistent patterns and/or systematic relationships between variables, and then to validate the findings by applying the detected patterns to new subsets of data. The ultimate goal of data mining is prediction - and predictive data mining is the most common type of data mining and one that has the most direct business applications. The process of data mining consists of three stages: (1) the initial exploration, (2) model building or pattern identification with validation/verification, and (3) deployment (i.e., the application of the model to new data in order to generate predictions).

Top RDBMS Enterprise E softwares : 1.
