Clustering is a technique in machine learning and data science that involves grouping together similar data points or objects into clusters or subsets. The goal of clustering is to find patterns and structures in data that may not be immediately apparent, and to group related data points together which can be used for further analysis. In this article, we are going to see how to implement clustering with the help of the SciPy library. SciPy provides us with various scientific computing tools to perform tasks like numerical integration, optimization, linear algebra, signal processing etc. It's used by researchers, scientists, engineers, ...

Introduction In Oracle databases, a schema is a logical grouping of related objects, such as tables, views, and stored procedures. Each schema belongs to a specific database user and has a set of associated privileges. To list all tables in a schema in an Oracle database, you can use one of the views in the data dictionary. The `ALL_TABLES` view contains one row for each table in the current schema, while the `DBA_TABLES` view contains one row for each table in the entire database. To list the tables in a schema, you can use a SELECT statement to query the ... Read More
