The concepts of Data Lake and Process Data Storage (PIMS, Historian) are often perceived as synonymous and even confused by professionals. The reason for this is their purpose: collecting and storing data. However, this is the only thing they have in common. In fact, there is a significant difference between these two systems, ranging from architecture to the tasks for which they are built. Three key differences between a process data warehouse and a data lake are: data…
Data Warehouse VS Data Lake Data Warehouse (DWH) is a convenient solution for enterprises and organizations, the principles of which we decided to cover in our today’s article. Based on our own experience in building data warehouses for financial institutions, we will also try to present all the benefits of using DWH as clearly as possible, as well as compare it with its “competitor” – cloud storage. The data warehouse is a subject-oriented information database that is…
Data volumes are increasing at an accelerated pace every year. The number of streaming data has increased significantly, and unstructured data is increasingly eclipsing its structured counterparts. As a result, a business that works with large databases has to process information before loading, which requires a lot of time and effort. But all the same, in the end, some of the information is lost, but or could be useful in the future. And an innovative product is called upon…
A data warehouse is a domain-specific, integrated, immutable and historical dataset organized for decision support purposes. Data warehouses allow more efficient, faster and better data provision for their analytical processing systems than conventional DBMS. Domain-specific means that the data in the store is aggregated according to the domains it describes, rather than the applications that use it.Integration means that the warehouse must support the joint storage of data of different nature, formats and types, reflecting different aspects of…
While we say data lake vs. data warehouse, these two technologies are actually quite complimentary. Read on to see why. Data lakes and data warehouses are critical technologies for business analysis, but the differences between the two can be confusing. How are they different? Is one more stable than the other? Which one is going to help your business the most? This article seeks to demystify these two systems for handling your data. What Is…
In this second post out of a four post series, discover how to build a data warehouse by reading the 5 steps listed below. Over this series of four posts, I explore the keys to a successful data warehouse. Last time, I started with design—a reasonable place to begin! The topic of this post is, build, with operation and maintenance to follow. Even with a beautiful design model in your mind’s eye, the question of how…
With each passing day, we accrue more data than ever. In the digital era, data warehouses are shaping up to be business-critical processes. Do you struggle with data warehouses? Are you baffled by the benefits they offer? Can you tell the difference between a “database” and a “data warehouse?” While the scope and scale of data warehouses may be a little overwhelming, at the end of the day they’re fairly simple to understand, and when used…
I have always been fond of two things: cooking and analytics. Believe it or not, there are many correlations between cooking your perfect recipe and getting that perfect analytical dataset that drives actions. Yes, we know that when in doubt, follow your heart, or so they say. And when it comes to your enterprise, the parallel should be that whether in doubt or not, always follow the data. Data is the driving force, the fuel…
Data warehouses have been around for several decades, serving as a central repository of integrated data from disparate sources that meet an enterprise’s reporting and data analysis needs. With the recent advent of newer analytical capabilities driven by machine learning algorithms and a wide array of computational paradigms and data formats, the data warehouse is undergoing a rather rapid modernization into an analytics platform and ecosystem. While there are several aspects that make up what can be…
