Data Warehousing And Business Intelligence Course – At its core, business intelligence is the ability to answer complex questions about your data and use those answers to make informed business decisions. To do this well, you need a data warehouse, which not only provides a secure way to organize and store all your data, but also a way to get the answers you need quickly, when you need them.

And this is an important role. By 2025, it is estimated that humanity will generate a total of 175 zettabytes of data. For context, that’s 175,000,000,000 terabytes.

Data Warehousing And Business Intelligence Course

Companies use data warehouses to manage transactions, understand data, and keep it all safe. In short, data storage makes large amounts of data more useful for organizations of all sizes.

This has made them the most popular information pipeline and business intelligence system in the world. And understanding how data storage works can help you realize the full potential of business data (it’s not as complicated as it seems).

A database is a data management system that stores large amounts of data for later use in processing and analysis. You can think of it as a big warehouse where trucks (ie the database) download data. This information is organized into organized rows and rows of disks that make it easy to find exactly what you are looking for later.

You can store this data in three different ways: on-premise storage, cloud storage, and cloud storage.

On-premises data storage runs on physical servers that your company owns and manages. Cloud data storage is generally online, and you pay for space on servers managed by another company, such as Amazon Redshift. Hybrid data storage is a combination of both on-premise and cloud storage, and companies that are transitioning to the cloud over time are using this option.

Data Warehousing And Analytics

With all data stored in one place, data warehouses use a specific data processing method called online data processing (OLAP), which is designed specifically for complex queries.

One way to think about it is that when you go to your database to query the relationship between one set of data and another, OLAP is a way of organizing and moving between rows and stacks of rows. should. solution. .

This is good for business intelligence because the questions you ask about your data to make decisions are not easy. Because databases use OLAP, they make finding the answers to these questions very complicated. As a result, they have become the foundation for many successful business intelligence systems.

In business intelligence, the data warehouse acts as the backbone of data storage. Business intelligence is based on complex questions and comparing large amounts of data to inform everything from day-to-day decisions to shifts in focus across the organization.

To simplify this, business intelligence consists of three functions: data analysis, data storage, and data analysis. Data analysis is usually facilitated by extract, transform, technology (ETL), which we will explain in detail below, and data analysis is done using business intelligence tools, such as .

The glue that holds this process together is the database, which acts as the data storage manager using OLAP. They combine, summarize, and transform information, making it easier to analyze.

Although databases act as the backbone of data storage, they are not the only technology involved in data storage. Many companies go through the database process before they get to the point where they need a full database.

As we explain in our Cloud Data Management eBook (an easy – and dare we say fun – read), there are generally four levels of data optimization: the data source, the data lake, the database, and information mart. Knowing when to invest in a database requires knowing each step, but at the end of the day, the database step is what unlocks the true power of your data.

Source data is any set of individual data such as databases, Excel spreadsheets, individual application reports, etc. It is organized (ie organized) but personal information that works well on its own but does not provide a big picture of your organization’s information as a whole.

For organizations that have graduated to needing to standardize their source data in one place, a data lake is becoming the next step. A data lake acts as a central repository for all raw, unstructured (ie, unstructured) data.

If data storage is like backing up a truck and unloading the data in an orderly manner, data lakes are like parking the cars and dumping all the data in the lake. James Dixon, who coined the term “data lake,” defined it as the raw state of data that, for those with fluid skills, is limited to discovery.

The disadvantage of a data lake is that the data is not ready for analysis. It’s not very structured, it can be duplicated, and to understand it, you need to tell the diver exactly what you’re looking for. Even then, the diver may not find exactly what you need after all that effort.

Like a database, a database organizes your data, but as we’ve established, it’s more structured and structured for better search. It is the single source of truth for all information that is easy to understand and navigate.

Data warehouses can be connected directly to source data, but today, we see many companies using data warehouses as the top layer of their data lake. Following Dixon’s analogy, if a data lake is fluid/data in a natural, unstructured environment, the data warehouse is where you manage it and prepare it for use.

Using databases for other tasks can be like swatting flies with a hammer. If, for example, the sales team repeatedly returns to the warehouse to make the same requests, you can set up a data mart.

What Is A Data Warehouse?

Data marts are sets of data created for specific use cases. In addition, Dixon explained, the sales team does not need to go to the control center every time they need water. The reservoir can be used to collect data/water into “water bottles” ready to drink.

In this data warehousing environment, data storage is always its backbone. It is organized and easy to understand (like a database), but it provides a comprehensive, centralized view (like a data lake), which makes it easier to use this data however you need (such as creating a data mart).

Databases have a complex organizational structure, but can be thought of as consisting of three basic components: storage, software, and performance. When making the decision to implement a data warehouse, you need to consider the investment required for all three.

Storage is a very simple option. As we mentioned before, you can organize your data storage locally, in the cloud, or use a hybrid system. Web photography, according to some, is on its way out. Cloud hosting is cheaper and easier because you rent space on someone else’s server. You don’t need to manage maintenance, you can upgrade up and down as needed, and there’s a feature set that’s constantly evolving every year. Bridging the gap between these two methods is the joint venture, which, as we mentioned earlier, is the preferred option for companies moving from on-premises to the cloud.

Data Warehouse & Business Intelligence

To get data from your database, you need to use a type of software that is often called ETL software. Extract, transform, load (ETL) is a process where data is extracted, prepared for use, and then loaded into a database.

Nowadays, we recommend and see many companies use an alternative to ETL called extract, load, transform (ELT). Often companies will extract data from a database, load it into a data lake, and then use a database to transform the data. Both ETL and ELT are facilitated with software such as and Stitch. If you want to learn more, check out our comprehensive resources on ETL, ELT, and even ETLT.

Of course, databases do not manage themselves. Work is an important part of keeping a database running because it is not just a process; They are “complete structures…” that require experts to set up and manage them.

The purpose of all this work is to organize and organize information, so that it can be easily understood. This is where business intelligence tools come in. They essentially sit on top of the database as a layer that helps you search, analyze, and visualize your data.

What Is Enterprise Data Warehousing?

While databases store data, business intelligence platforms analyze the data. When you get these two systems working together seamlessly, you will unlock all the benefits of business intelligence.

Business intelligence tools fill the “data analysis” level of business intelligence, but they get their name because they are the culmination of two other processes: data crunching and data warehousing.
