What is evolution of database technology?
Evolution of Database The first wave consisted of network, hierarchical, inverted list, and (in the 1990’s) object-oriented DBMSs; it took place from roughly 1960 to 1999. The relational wave introduced all of the SQL products (and a few non-SQL) around 1990 and began to lose users around 2008.

How the evolution of database technology led to data mining?
Machine learning – It is the combination of Classical and AI stats in order to build itself up. Over the years this huge amount of data has been collected and stored, but it has increased the complexity to retrieve that data whenever needed. Data retrieval has lead to the term of data mining.

How are databases developed?
Steps for developing a database are simple and consist of four stages namely, requirements elicitation, conceptual modeling, logical modeling, and physical modeling. It is significant to understand that Database Management is your key to handle big chunks of data more effectively.
What are the function of DBMS?
A database management system (DBMS) is a software tool that enables users to manage a database easily. It allows users to access and interact with the underlying data in the database. These actions can range from simply querying data to defining database schemas that fundamentally affect the database structure.
