What is OLAP and what types of OLAP tools are available?
OLAP is an acronym for On-Line Analytical Processing. OLAP is a software technology classification that allows analysts, managers, and executives to get insight into information through fast, consistent, interactive access to data that has been transformed from raw data to reflect the true dimensionality of the company as perceived by the clients. Show OLAP is based on a pretty straightforward notion. Most queries that are generally difficult to execute over tabular databases, such as aggregation, joining, and grouping, are pre-calculated. These queries are calculated as part of the OLAP cube’s ‘building’ or ‘processing’ operation. This process takes place overnight, and data will have been updated by the time end users arrive at work. In this article, you will learn about OLAP and the different OLAP Models, and their advantages and disadvantages. Table of Contents
What is OLAP?Image SourceOLAP (Online Analytical Processing) is a computer approach that allows users to extract and query data quickly and selectively to examine it from many perspectives. Trend Analysis, Financial Reporting, Sales Forecasting, Budgeting, and other planning tasks are frequently aided by OLAP Business Intelligence queries. For example, a user can ask for data to be analyzed to see a spreadsheet showing all of a company’s beach ball products sold in Florida in July, compare revenue figures with those for the same products in September, and then compare other product sales in Florida during the same time. Applications of OLAPDue to the development of Data Science approaches within enterprises, OLAP systems have become increasingly popular in recent years. Because Data Analytics necessitates advanced Data Processing, a completely different database was developed to accommodate complex query requests. As a result, OLAP-powered Data Warehouses were developed to support analytical operations such as Roll-Up, Drill-Down, Slice and Dice, and Pivot Tables. Here are several OLAP Analytics Operations:
OLAP Models are integrated with Data Warehouses to provide for easy data grouping, aggregation, and joining. Because elaborate Data Modeling is resource-intensive, advanced analytics becomes slow with typical relational databases. However, using OLAP Models, data can be sculpted into a variety of shapes, which can speed up Big Data Analytics. When to use OLAP?OLAP is great for data mining, business intelligence, and complicated analytical calculations, as well as financial analysis, budgeting, and sales forecasting in corporate reporting. The OLAP cube is at the heart of most OLAP databases, allowing you to swiftly query, report on, and analyze multidimensional data. OLAP allows you to organize data in a multidimensional model that makes it simple for business users to comprehend and use the data in a business context, such as a budget.

Relational OLAP Models (ROLAP)Image SourceROLAP stands for Relational OLAP Model, a relational OLAP application. These are servers that sit between a relational back-end server and the user front-end tools. They save and manage warehouse data via a relational or extended-relational database management system, and they employ OLAP middleware to fill in the gaps. ROLAP models execute optimization for each DBMS back end, aggregate navigation logic implementation, and other tools and services. ROLAP systems mainly use data from relational databases, where the base data and dimension tables are stored as relational tables. This model also allows for multidimensional data analysis. This method works by modifying the data in a relational database to simulate the slicing and dicing functionality of standard OLAP. Each method of slicing and dicing is essentially the same as adding a “WHERE” clause to a SQL statement. Advantages
RDBMS already comes with a lot of features. So ROLAP technologies, (which works on top of the RDBMS) can control these functionalities. Disadvantages
Multidimensional OLAP Models (MOLAP)Image SourceMOLAP stands for Multidimensional OLAP Model, an application based on multidimensional DBMSs. The foundation of a MOLAP model is a native logical model that allows multidimensional data and operations directly. Data is physically stored in multidimensional arrays and accessed using positional algorithms. The scalability of ROLAP technology is generally higher than that of MOLAP technology. One of the key differences between MOLAP and ROLAP is that data is summarised and stored efficiently in a multidimensional cube rather than a relational database. Data is formatted into proprietary forms per the client’s reporting requirements in the MOLAP model, with computations pre-generated on the cubes. Advantages
Disadvantages
Hybrid OLAP Models (HOLAP)Image SourceHOLAP or Hybrid OLAP Model is an application that combines relational and multidimensional approaches. HOLAP combines MOLAP and ROLAP’s greatest characteristics into a single architecture. HOLAP systems store a larger amount of detailed data in relational tables, while aggregations are saved in pre-calculated cubes. For defined data, HOLAP can drill down from the cube to the relational tables. A hybrid OLAP model is provided by Microsoft SQL Server 2000. Advantages
Disadvantages

Web-Enabled OLAP Models (WOLAP)WOLAP refers to an OLAP program that may be accessed through a web browser. WOLAP is a three-tiered architecture that consists of three components: a client, middleware, and database server, as opposed to standard client/server OLAP systems. One example of this type of model in HTML solution is an OLAP tool that allows the user to execute some specific OLAP queries or reports from a browser and no other functionality would be available. Desktop OLAP Models (DOLAP)DOLAP (Desktop OLAP) Model allows a user to download a piece of data from a database or source and work with it locally or on their desktop. Mobile OLAP Models (MOLAP)MOLAP or Mobile OLAP (MOLAP) allows users to utilize their mobile devices to access and work on OLAP data and applications. Spatial OLAP Models (SOLAP)SOLAP (Spatial OLAP) combines the capabilities of both GIS and OLAP into a single user interface. It helps with both spatial and non-spatial data management. Spatial OLAP, for example, can be used to analyze regional weather trends. Assume there are approximately 3,000 weather probes strewn across British Columbia (BC), each recording daily temperature and precipitation for a small area and transferring data to a provincial weather station. Challenges of OLAP ModelsSome disadvantages of OLAP Models are:
ConclusionMany Business Intelligence (BI) solutions use OLAP (Online Analytical Processing), a sophisticated technology that identifies data, provides report viewing capabilities, performs complicated analytical calculations, and predicts scenarios, budgets, and forecasts. It operates by collecting data from a variety of sources (such as a spreadsheet, video, XML, and so on) and storing it in data warehouses, which are then cleansed and structured into data cubes on which the user’s queries can be executed. Extracting complex data from a diverse set of data sources can be a challenging task and this is where Hevo saves the day!

What is OLAP and types of OLAP?There are three main types of OLAP: MOLAP, HOLAP, and ROLAP. These categories are mainly distinguished by the data storage mode. For example, MOLAP is a multi-dimensional storage mode, while ROLAP is a relational mode of storage. HOLAP is a combination of multi-dimensional and relational elements.
