1. Differentiate 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 problems associated with the data file environment, and the data can be shared between data users. .The search for information can provide the techniques of storage and retrieval of data and often of dissemination recorded in particular through the use of a computerized system of techniques of storage and retrieval and often of dissemination in particular via the use of recorded computer data. Types of database management system are centralized and distributed. A centralized database stores all related files in a physical, distributed file and contains complete copies of a database or parts of a database. Types of recovery they offer to users. Many previous attempts have been made to couple database management system and information retrieval systems, i.e. integrating the two into a unified framework. The function of the database management system can be designed to manage the data and information that large organizations within a company involve in both defining the structure The information retrieval function has dealt with, on the one hand, from various sources of information and, on the other hand, from the needs of users. It must analyze the content of information sources as well as user queries, then compare them to retrieve the relevant elements. The database management system function can ensure that the security of stored information is not lost or compromised, despite system failures or attempts to do something that is not authorized. If the data must be shared between several users, the system must avoid...... the middle of the paper management profession. The first question to answer is the origin of the term unstructured data. The term is derived because a database technician cannot log data on a traditional schedule and access the data with SQL (Structured Query Language). Since the term in SQL is structured surgery and data cannot be retrieved from SQL, then this data must be clean and unstructured. Works Cited • abhisyek Taneja. (2000). Types of database system.
