Understanding OLAP

What does OLAP stand for?

• OLAP

• OLUP

• OLIP

• OLTP

What are the characteristics of OLAP?

• Limited data handling capacity, lack of support for complex queries

• Single-dimensional data representation, slow query performance

• Inability to handle large volumes of data, slow query performance

• Multidimensional data representation, support for complex queries, fast query performance, ability to handle large volumes of data

What is the main difference between OLTP and OLAP?

• OLTP is for transaction processing, while OLAP is for data analysis.

• OLTP and OLAP are interchangeable terms.

• OLTP and OLAP serve the same purpose.

• OLTP is for data analysis, while OLAP is for transaction processing.

What are some common OLAP operations?

• Drill-up

• Group-by

• Drill-down, roll-up, slice, dice, pivot, drill-across

• Expand

• Filter

Name the three types of OLAP.

• TOLAP

• MOLAP, ROLAP, HOLAP

• SOLAP

• DOLAP

Explain ROLAP.

• ROLAP stands for Random Online Analytical Processing

• ROLAP is Relational Online Analytical Processing.

• ROLAP refers to Real-time Online Analytical Processing

• ROLAP is an acronym for Remote Online Analytical Processing

Explain MOLAP.

• MOLAP is a type of OLAP that stores data in a multidimensional cube for faster query performance and complex analytical calculations.

• MOLAP is a type of OLAP that uses a relational database for storage.

• MOLAP is a type of OLAP that only supports simple queries.

• MOLAP is a type of OLAP that does not involve multidimensional data.

Explain HOLAP.

• HOLAP is a hybrid approach that combines ROLAP and MOLAP features.

• HOLAP is a programming language

• HOLAP is a social media platform

• HOLAP is a type of hardware

Which type of OLAP stores data in a relational database?

• Hybrid OLAP (HOLAP)

• Online Transaction Processing (OLTP)

• Multidimensional OLAP (MOLAP)

• Relational OLAP (ROLAP)

Which type of OLAP stores data in a multidimensional database?

• HOLAP

• MOLAP

• SOLAP

• DOLAP
