More about Business Inteligence
Business Intelligence (BI) comprises both the strategies and the technologies that are used by enterprise-class companies to analyze collections of data. The analysis of such data has become key for corporations to strategize for the future. And given how competitive the world of business has become, every advantage (regardless of how small) can mean the difference between success and failure.
Although you might think you can get by with the traditional database and web-based GUI, there are 2 very important benefits to migrating to a data warehouse:
- Better data - you'll be able to collect more consistent and relevant information from a particular source.
- Faster decisions - because the data stored in a warehouse is in a more consistent format, the systems you use for analysis can arrive at decisions much faster.
It's important to understand that a data warehouse isn't just a single collection of data. Rather, a data warehouse is a collection of stored databases. That means you could have different databases from a variety of sources or each of which houses data specific to such things as regions, clients, or products.
Data Lake or Not?
You might have heard the term "data lake." Although this is another important concept, you need to understand that a data warehouse and a data lake are 2 very different things. A data lake is a collection of multiple types of data, including raw, unstructured, and structured. These different sets of data are stored in their raw format until they are needed. A data warehouse, on the other hand, stores data in organized files and folders that is ready to be used by analytics tools.
What You'll Need to Build a Data Warehouse
First of all, a data warehouse isn't something your IT admin can download and point-and-click their way to deploying. This is a very complicated, involved, and lengthy procedure. That means you'll need to have the required staff to do in-depth research and who fully understand how data works.
So the first thing you're going to need to do is to collect your data, which can come from nearly any source. This can be ad performance, website or app tracking, e-commerce, marketing, customer relations, customer support, or financial data. You can collect that data with tools like Google Analytics, Snowplow, Heap, your company HRM tool, or Zendesk. That means you're going to need staff trained in the extraction of data from those platforms.
Once you have your data collected, you'll then need to turn to a company that offers data warehouse solutions. Yes, you could always build your own in-house data warehouse, but why reinvent the wheel? Some of the more startup-friendly data warehouse services include:
Of the above services only Panopy offers built-in, easy-to-use connectors for nearly any type of data you've collected. This makes Panoply the most user-friendly, Snowflake can get expensive, and Amazon Redshift can be the most complicated. However, if you expect your data warehouse to grow fast and large, Amazon certainly has the infrastructure to house any size data warehouse you need.
Next, you'll need the right ETL tool. ETL stands for Extract, Transform, Load. This will only be necessary if you opt to go with a data warehouse solution that doesn't include a connector for your data. If that's the case, you'll need to turn to the likes of Singer, Stitch, Blendo, or Fivetran. Naturally, you'll need staff members capable of using these tools.
Finally, you'll need to employ the right analytics tools, such as Google Data Studio, Looker, Metabase, or Mode.
Once you have all of those pieces together, your data warehouse is ready to be used.
Conclusion
As you can probably tell, creating a data warehouse isn't an easy task. That's why you'll need to make sure to hire data warehouse developers who are capable of putting these technologies together, so your business can make the most out of your data and raise your business intelligence game to the next level.
