UNION combines the results of two or more SELECT statements, while UNION ALL combines all rows from the results of two or more SELECT statements.

• UNION removes duplicate rows from the result set, while UNION ALL does not.

• UNION is slower than UNION ALL because it performs a distinct operation, while UNION ALL simply combines the results.

• Example: SELECT column1 FROM table1 UNION SELECT column1 FROM table2;

• Example: SELECT column1 FROM table1 UNION ALL SELECT column1 FROM table2;

• Profiles can be assigned to roles, public groups, or individual users.

• Examples of sharing rules profiles include granting access to specific accounts for a sales team, or allowing HR to view sensitive employee data.

Optimization techniques involve various syntaxes for improving efficiency.

• Gradient descent: update parameters in the opposite direction of the gradient of the loss function

• Genetic algorithms: mimic the process of natural selection to find optimal solutions

• Simulated annealing: probabilistic technique for approximating the global optimum of a given function

• Linear programming: optimize a linear objective function subject to linear equality and inequality constraints

Basic pillars are fundamental principles or core values that guide decision-making and behavior.

• Basic pillars serve as a foundation for an organization's culture and operations.

• They help define the organization's identity and purpose.

• Examples of basic pillars include integrity, teamwork, innovation, and customer focus.
