Indian Political Action Committee Interview Questions, Process, and Tips

Indexes are data structures that improve the speed of data retrieval operations on a database table.

• Indexes are created on one or more columns of a table.

• They store a copy of the indexed data in a separate structure.

• This allows the database to quickly locate the data when a query is executed.

• Indexes can be unique or non-unique, clustered or non-clustered.

• Creating too many indexes can slow down data modification operati

List is mutable and tuple is immutable in Python.

• Lists use square brackets [] while tuples use parentheses ().

• Lists can be modified while tuples cannot be modified once created.

• Lists are used for collections of homogeneous items while tuples are used for heterogeneous items.

• Lists are slower than tuples in terms of performance.

• Lists are used for dynamic data while tuples are used for static data.

Use indexing, partitioning, and sharding to handle large datasets in RDBMS.

• Create indexes on frequently queried columns to speed up search operations.

• Partition tables based on a specific column to distribute data across multiple disks.

• Use sharding to horizontally partition data across multiple servers.

• Consider using NoSQL databases for unstructured data or when scalability is a concern.
