OLAP (Online Analytical Processing) is a category of data processing that enables users to analyze multidimensional data interactively and perform complex queries on large datasets for business intelligence (BI), reporting, and strategic decision-making. In SaaS and B2B environments, OLAP supports executive dashboards, revenue analysis, product usage trends, and cohort tracking.
What Is OLAP?
OLAP systems are optimized for read-heavy workloads that involve slicing, dicing, drilling, and aggregating large amounts of data across multiple dimensions — such as time, region, customer segment, or product line.
OLAP allows businesses to explore “what happened, when, where, and why” by enabling fast, dynamic data exploration and summarization.
OLAP vs OLTP
| Feature | OLAP | OLTP |
|---|---|---|
| Purpose | Data analysis & reporting | Transactional processing |
| Data Volume | Large historical datasets | Small, real-time transactions |
| Read/Write Ratio | Read-intensive | Write-intensive |
| Schema | Star or snowflake schema | Normalized schema |
| Example | Revenue dashboard | E-commerce checkout system |
Key OLAP Concepts
- Multidimensional Model – Data is organized into “cubes” with dimensions like time, geography, and product
- Slicing – Extracting a specific dimension from a cube (e.g., all sales in Q1)
- Dicing – Creating a sub-cube based on two or more dimensions
- Drill-Down / Roll-Up – Zooming into granular details or summarizing to a higher level
- Aggregation – Summing or averaging data across dimensions
Types of OLAP Systems
| Type | Description |
|---|---|
| MOLAP | Multidimensional OLAP – uses pre-aggregated data cubes |
| ROLAP | Relational OLAP – runs queries directly on relational databases |
| HOLAP | Hybrid OLAP – combines MOLAP and ROLAP for flexibility and performance |
Why OLAP Matters in SaaS and B2B

FAQ
What is the difference between OLAP and OLTP?
OLAP is for analytical querying of large datasets, while OLTP is for real-time transactions like inserts, updates, and deletes.
What is an OLAP cube?
An OLAP cube is a multidimensional data structure that allows users to view data from multiple perspectives — like sales by time, region, and product category.
Is OLAP still relevant with modern cloud data platforms?
Yes. While the architecture has evolved, OLAP-style querying is embedded in tools like Snowflake, BigQuery, and Looker, and is critical for BI use cases.
How is OLAP used in SaaS dashboards?
Can CUFinder data be used in OLAP cubes?
Yes. CUFinder-enriched data can enhance dimensions and measures in OLAP cubes, improving accuracy and segmentation.
