Business intelligence tools in data warehousing

The course gives an overview of how business intelligence technologies can support decision making across any number of business sectors. These technologies have had a profound impact on corporate strategy, performance, and competitiveness and broadly encompass decision support systems, business intelligence systems, and visual analytics.

Modules are organized around the business intelligence concepts, tools, and applications, and the use of data warehouse for business reporting and online analytical processing, for creating visualizations and dashboards, and for business performance management and descriptive analytics.

Like a physical warehouse, it operates as storage for data that has been extracted from another source.

Many organizations have proprietary data warehouses that store information on performance metrics, sales quotas, lead generation stats and a variety of other information.

Data warehouses can perform some analytics capabilities: using the extract, transform, load ETL process, data warehouses can perform complex queries that transactional databases cannot handle.

It also has the ability to negotiate different data storage schemas based on the data type to kickstart the cleaning process. Once data has entered a warehouse, it cannot be altered. Data warehouses only perform analysis of historical data and cannot provide real-time data or make future predictions. Compare BI Software Leaders. Some people believe that a data warehouse merely stores information to form the back end of business intelligence and that they are completely separate entities.

To understand how BI and DW work together, we need to first separate the concept of business intelligence from the tools which support it. BI Tools are software applications that facilitate BI analysis by creating visualizations and reports as well as enabling OLAP online analytical processing. Data warehouses are another facet of a BI toolset and are concerned specifically with aggregating data.

Data warehouses are one of many steps in the business intelligence process, so the term BIDW is something of a generalization. BI and DW is a bit more accurate, and just using the general umbrella of BI to include business analytics, data warehousing, databases, reporting and more is also appropriate. All of these types of solutions make up a vast ecosystem of intelligence systems with common purposes.

Another pair of terms that are often confused are databases and data warehouses. While the two may seem similar, there are plenty of differences that make them easy to tell apart to the trained eye.

A database is a repository of data where the information is organized, typically in a column, row and table format. A database is periodically indexed to make sure the information is structured and accessible.

Databases can perform online transaction processing OLTP functions and respond to queries such as a search.

Both databases and data warehouses are relational data systems , which means that they store, organize and transport data points that are related to each other in some way. They are built using SQL, or structured query language, and can be accessed by users performing searches.

A database is designed to record data, perform fundamental operations and transactions and capture data through OLTP processes. Conversely, a data warehouse performs OLAP to analyze data in order to present it to your queries.

Databases are application-oriented, typically limited to a single application like an HR software solution , and stores detailed real-time data. Data warehouses are subject-oriented collections of historical data that can perform complex queries to retrieve summarized data.

So to break this down into a practical example, data warehouses draw and store data from databases. Those databases are often being updated constantly and reflect real-time data from whatever source it is drawing from. Data warehouses can draw information this way from a variety of databases to condense it for user queries. A robust BI architecture describes various layers and components with different capabilities that produce dashboards and reports. Cloud data warehouses are fully online, and you pay for space on servers that another company manages, like Amazon Redshift.

Hybrid data warehouses are a mix of both on-premise and cloud, and companies making the transition to the cloud over a period of time use this option. With all the data stored in one place, data warehouses use a specific approach to process data called online analytical processing OLAP , which is specifically designed for complex queries.

One way to think about it is that when you go to your data warehouse to ask a question about the relationship between one set of data and another, OLAP is a way of organizing and moving among the rows and rows of shelves to quickly find that information. This is great for business intelligence because the questions you ask about your data in order to make decisions are rarely simple. Because data warehouses use OLAP, they make finding answers to these complex questions very efficient.

In business intelligence, data warehouses serve as the backbone of data storage. Business intelligence relies on complex queries and comparing multiple sets of data to inform everything from everyday decisions to organization-wide shifts in focus. To facilitate this, business intelligence is comprised of three overarching activities: data wrangling, data storage, and data analysis. The glue holding this process together is data warehouses, which serve as the facilitator of data storage using OLAP.

They integrate, summarize, and transform data, making it easier to analyze. Many companies go through a data storage hierarchy before reaching the point where they absolutely need a data warehouse. As we explain in our Cloud Data Management eBook a super easy — and dare we say fun — read , there are generally four stages of data sophistication : source data, data lakes, data warehouses, and data marts. Knowing when to invest in a data warehouse requires you to know each stage, but at the end of the day, the data warehouse stage is what unlocks the true power of your data.

Source data is any individual set of data like databases, Excel spreadsheets, individual application reports, etc. For teams who have graduated to a need to centralize their source data into one place, a data lake is increasingly becoming the next step.

A data lake serves as a central repository for all raw, unstructured i. If a data warehouse is like backing up a truck and unloading the data in an orderly fashion into a well-organized shelving system, data lakes are like backing the truck up and dumping all the data into, well, a lake.

The drawback of a data lake is that the data is not ready for analysis. You can also have a look at the unbeatable pricing that will help you choose the right plan for your business needs.

Skip to content. The benefits of using a Data Warehouse are as follows: Better Quality Data : The data from all the data sources go through various transformations that ensure that the data stored in the Data Warehouse is of the best quality possible. This means that various inconsistencies that might be present in the Operational Data have been addressed to ensure that only consistent and good quality data is present in the Data Warehouse. Faster Decision Making : Since the data in the Data Warehouse is already consistent and of high quality, it can be considered to be in a form suitable for analysis.

Hence, the business team can perform the required analysis in less time without worrying about inaccurate results. Small Transactions. Large Number of Users. High Availability and Concurrency.
