1. Distinguish between database management system and information retrieval system by focusing on their functionality. Database Management System Information Retrieval The database management system can provide access to all data, alleviating many of the problems associated with the data file environment, and the data can be shared between users of the data Information Retrieval can provide data storage and retrieval techniques and often dissemination of recorded data, especially through the use of a computerized system, storage and retrieval techniques and often dissemination, especially through the use of recorded computer data. Database management system types are centralized and distributed. A centralized database stores all related files in a single physical and distributed storage has complete copies of a database or parts of a database. Recovery types provided to users. Many previous attempts have been made to couple database management system and information retrieval systems together, integrating the two into a unified framework. The database management system function can be designed to manage data and information that large bodies within a company management involves both defining the structure. The information retrieval function deals on the one hand with different sources of information and on the other, user needs. It must analyze the content of information sources and user requests and then match them to retrieve the relevant elements. The database management system function can ensure that the security of the stored information is not lost or compromised, despite system crashes or attempts at something that is not allowed. If data is to be shared among multiple users, the system must avoid...... middle of paper ......agement profession. The first question to answer is the origin of the term unstructured data. The term comes from the fact that a database engineer cannot save data in a traditional schedule and access data with SQL (Structured Query Language). Since the term in SQL is structured surgery and the data cannot be retrieved from SQL, such data must be clear and unstructured. Works Cited • abhisyek Taneja. (2000). Types of database system.
