Multidimensional Database Management System


A Multidimensional Database Management System (MDBMS) is a type of database management system that stores data in a multidimensional array to optimize data warehouse and online analytical processing (OLAP) performance. By allowing multiple dimensions, it enables complex queries and analysis. This method facilitates faster data retrieval, as it uses the array structure to map out data locations effectively.

Key Takeaways

Three Main Takeaways about Multidimensional Database Management System

  1. Increased Query Performance: Multidimensional Database Management Systems (MDDBMS) are designed to handle complex queries and analysis operations. They enable faster data retrieval. This is achieved by storage of data in multi-dimensional arrays instead of the standard two-dimensional tables seen in relational databases. The data is pre-aggregated into the cubes, reducing the time and resources needed to perform complex calculations.
  2. Data Analysis and Visualization: MDDBMS allows users to view data from multiple dimensions, enabling them to uncover insights that would be difficult to discern in a two-dimensional relational database. This feature is especially beneficial in areas such as business intelligence and data analysis, where visualizing relationships and trends in data is crucial for decision-making.
  3. Scalability: Multidimensional databases are highly scalable, handling large volumes of data and multiple concurrent users efficiently. They can scale to accommodate increased data loads without noticeable performance degradation. This feature makes them suitable for large-scale data warehousing and online analytical processing (OLAP) applications.


The term “Multidimensional Database Management System” (MDBMS) is important in technology as it refers to a type of database system that enables faster data retrieval, querying, and data processing for complex queries and large data volumes. This system stores data in a multidimensional array, meaning users can analyze data from multiple perspectives and dimensions, beneficial for businesses with complex data analysis needs like trend analyses, data warehousing, and OLAP (Online Analytical Processing). Furthermore, since MDBMS supports data aggregation and association, it aids in enhancing business decision-making processes, making it a vital tool in the realms of big data and business intelligence.


A Multidimensional Database Management System (MDBMS) is a crucial piece of technology used in managing databases that focus on analytical processing (OLAP), data warehousing, and other related applications. In contrast to traditional relational databases, MDBMS allows for faster data processing by organizing data in a multidimensional manner, similar to an array. This organization model makes it easier to visualize relations between data points across various dimensions. It’s often used in business intelligence applications where complex analyses and computations are necessary.The primary purpose of a MDBMS is to provide an efficient data retrieval method which helps in speedy access and manipulation, especially in scenarios involving large data sets. For example, companies dealing with business analytics can use MDBMS to churn out complex queries and analyses involving multiple metrics and dimensions in comparatively less time. Moreover, its multidimensional structure provides an intuitive, easy-to-understand model for business users, thus facilitating decision-making and strategic planning. MDBMS is particularly effective in applications like sales forecasting, market research, trends analysis, financial management, and budgeting where high-speed data processing is crucial.


1. OLAP Systems: Online Analytical Processing (OLAP) systems are one of the best examples of a Multidimensional Database Management System. These systems allow users to analyze database information from multiple database systems simultaneously. OLAP systems organize large amounts of data and business metrics by categories and attributes. For instance, Oracle Essbase, a business analytics system, is an example of an OLAP system.2. Data Warehousing: Data warehousing involves the storage of data from various sources in a multidimensional database for reporting and data analysis purposes. For example, Amazon Redshift is a fully managed, petabyte-scale data warehouse that makes it simple and cost-effective to analyze all your data using your existing business intelligence tools.3. Business Intelligence (BI) Systems: BI systems use multidimensional databases for organizing and analyzing large amounts of data. This helps to provide timely business information to business leaders. Microsoft Analysis Services, a part of Microsoft SQL Server, is an example of a BI system involving multidimensional databases to provide insightful business intelligence.

Frequently Asked Questions(FAQ)

**Q1: What is a Multidimensional Database Management System?** A1: A Multidimensional Database Management System is a type of database management system that allows for data to be analyzed and represented in multiple dimensions. It’s typically used in complex analytical applications such as financial reporting, trend analysis, and data warehousing.**Q2: How does a Multidimensional Database Management System differ from a Relational Database Management System?**A2: In a Relational Database Management System, data is accessed linearly, row by row. However, a Multidimensional Database Management System allows data to be accessed and analyzed in various ways because it has the capacity to hold and model data from various dimensions.**Q3: What are some advantages of using a Multidimensional Database Management System?**A3: Multidimensional Database Management Systems enables quicker data retrieval, better processing speed, and advanced data analytics. It also provides users with the ability to view data from different perspectives, increasing the ways in which data can be interpreted and utilized.**Q4: What’s an example of a Multidimensional Database Management System?**A4: OLAP (Online Analytical Processing) is a prime example of a multidimensional database management system. OLAP systems are widely utilized in industries where complex analytical processes are required, such as business intelligence and data mining.**Q5: What industries typically utilize Multidimensional Database Management Systems?**A5: Industries that require complex data analysis, such as finance, retail, and healthcare, often prefer to use Multidimensional Database Management Systems. These industries require the ability to analyze data from multiple perspectives to make impactful decisions.**Q6: How does data storage work in a Multidimensional Database Management System?**A6: In a Multidimensional Database, data is stored in data cubes instead of tables. These data cubes allow for the representation of data in three or more dimensions, making it useful for complex data analysis.**Q7: What kind of data is most suitable for a Multidimensional Database Management System?**A7: Multidimensional Database Management Systems are best suited for handling large volumes of data, especially for data that need to be analyzed from multiple angles or dimensions, such as sales data (which could be analyzed by product, region, time period, etc.)
