Guide to Open Source OLAP Software

Open-source OLAP (Online Analytical Processing) software is a type of database management system that allows users to access and analyze massive amounts of data quickly and easily. The open-source approach offers the benefit of having multiple contributors contribute to the development of the software, making it more easily maintainable and generally easier to use. Open source OLAP also tends to have lower costs as compared to other proprietary solutions.

OLAP systems are organized into multidimensional cubes that allow for easy drilling down into various facts associated with what’s being analyzed. For example, an analyst could look at sales data by product, region, time period or any combination thereof. This kind of analysis helps users quickly identify opportunities in their data and drive better decision-making processes within their organizations.

The open-source approach offers tremendous flexibility when using OLAP software since developers can modify the existing platform or customize existing features without requiring additional permissions or fees from vendors. Not only does this often save costs but it ensures that researchers get exactly what they need out of the system with little effort or delay.

Open source OLAP software is typically powered by a relational database such as MySQL, PostgreSQL or MariaDB which means that it supports several common query languages like SQL (Structured Query Language). Popular solutions include Pentaho Business Analytics Suite, JasperSoft BI Suite Professional Edition, Birst Cloud Business Intelligence Platform and Apache Kylin Online Analytical Processing Services among others.

What Features Does Open Source OLAP Software Provide?

  • Security: Open source OLAP software provides users with secure data access and the ability to control who has access to certain information. It also provides multiple levels of security, allowing administrators to create different passwords for individual users or groups.
  • Reporting: Open source OLAP software offers a wide range of reporting features that allow users to quickly identify patterns in their data. These features include filtering, slicing, drill down and roll up capabilities so that users can easily analyze their data in a holistic manner.
  • Performance Optimization: Open source OLAP software comes with built-in performance optimization tools that help maximize query speed and reduce resource utilization. This ensures the system is running efficiently at all times.
  • Data Exploration: Users are able to easily explore new sources of data using open source OLAP software's powerful exploration tools including data mining, predictive analytics, pattern discovery and visualizations such as charts and graphs.
  • Scalability: Most open source OLAP solutions are designed from the ground up to be highly scalable so they can handle large amounts of data with ease. They feature caching capabilities, partitioning schemes and distributed processing tools that allow for easy scaling up when more resources are needed.

What Are the Different Types of Open Source OLAP Software?

  • Multi-Dimensional OLAP (MOLAP): This type of open source OLAP software is used to store and analyze data in a multi-dimensional format. MOLAP sites use pre-calculated cubes of data that are stored on specialized servers, making them much faster than traditional queries against relational databases.
  • Relational OLAP (ROLAP): This type of open source OLAP software is based on querying relational databases directly in order to construct multi-dimensional views. Compared with MOLAP, ROLAP can be more flexible because it does not require pre-calculated cubes and can query multiple sources at the same time.
  • Hybrid OLAP (HOLAP): This type of open source OLAP software uses a combination of MOLAP and ROLAP to provide the best of both worlds. It uses pre-calculated cubes for quick data retrieval, but also has the flexibility to query relational databases directly when needed.
  • Online Analytical Processing (OLAP): This type of open source OLAP software is based on special algorithms for analyzing data stored in multiple dimensions. These algorithms can help with complex queries and calculations that are not possible with traditional methods.
  • Data Mining: This type of open source OLAP software focuses on discovering patterns and trends in large sets of data that would otherwise be too difficult or time consuming to uncover through manual analysis.

What Are the Benefits Provided by Open Source OLAP Software?

  1. Cost Savings: Open source OLAP software can provide organizations with significant cost savings by eliminating the need to purchase proprietary or expensive OLAP software. Additionally, open source alternatives require no licensing fees, meaning a company's costs remain constant.
  2. Flexibility: With open source OLAP software, organizations have the flexibility to tailor their solutions to meet specific business needs. This allows them to develop highly customized solutions for their unique requirements and not be restricted by pre-existing conditions of more rigid enterprise software packages.
  3. Security: Open source OLAP applications are generally considered more secure than traditional systems because they're built from shared code that is constantly reviewed and updated by a large community of developers. This means that security vulnerabilities in the core code are quickly identified and patched before they can cause any damage.
  4. Scalability: Many open-source OLAP solutions offer scalability options that allow organizations to increase capacity as needed without having to invest heavily in new hardware or infrastructure. This gives companies the ability to start small and grow as demand increases.
  5. Support: While it might not always be easy to find technical support for an open source solution, many of these products have active forums where users can exchange tips and advice on how best to use them in order to maximize value. Additionally, there are also paid services available from third-party providers who specialize in providing expert support for such products.

What Types of Users Use Open Source OLAP Software?

  • Business Analysts: These users work with data to gain insights, create reports, and devise strategies for their companies. They typically use OLAP software to analyze large amounts of complex data in order to draw conclusions that can be used in business planning or decision-making.
  • IT Professionals: These users are responsible for maintaining the company's databases and IT systems, including any open source OLAP software. They usually utilize the software for monitoring performance, as well as troubleshooting and resolving technical issues.
  • Database Administrators: As the name implies, these professionals manage databases and ensure that they are running optimally. They often use open source OLAP software to review database activity and identify potential problems before they can become serious.
  • Data Scientists: Data scientists use advanced techniques like machine learning and statistical analysis to uncover trends from vast stores of data. Open source OLAP software helps them quickly manipulate large datasets so that they can generate more accurate models with greater relevance.
  • Developers & Programmers: This group includes developers of all types — web, mobile app, enterprise application — who need access to efficient ways of storing and processing data in order to power their applications. Open source OLAP software provides them with a fast way of dealing with huge volumes of information without having to write custom code or run complicated queries every time they need it.
  • Financial Analysts: Finance analysts rely on numbers provided by open source OLAP solutions in order to let stakeholders know how their investments are performing compared against market averages or other metrics over time. Having easy access to this kind of information allows them better decision-making capabilities when making investment decisions in markets around the world.
