When it comes to data, there are two main types: data lakes and datawarehouses. What is a data lake? An enormous amount of raw data is stored in its original format in a data lake until it is required for analytics applications. Which one is right for your business? Let’s take a closer look.
The goal of this post is to understand how data integrity best practices have been embraced time and time again, no matter the technology underpinning.

Dataquality plays a significant role in helping organizations strategize their policies that can keep them ahead of the crowd. Hence, companies need to adopt the right strategies that can help them filter the relevant data from the unwanted ones and get accurate and precise output.
Poor dataquality is one of the top barriers faced by organizations aspiring to be more data-driven. Ill-timed business decisions and misinformed business processes, missed revenue opportunities, failed business initiatives and complex data systems can all stem from dataquality issues.
Discover the nuanced dissimilarities between Data Lakes and DataWarehouses. Data management in the digital age has become a crucial aspect of businesses, and two prominent concepts in this realm are Data Lakes and DataWarehouses. It acts as a repository for storing all the data.
Datawarehouse (DW) testers with data integration QA skills are in demand. Datawarehouse disciplines and architectures are well established and often discussed in the press, books, and conferences. Each business often uses one or more data […]. Each business often uses one or more data […].
As such, the quality of their data can make or break the success of the company. This article will guide you through the concept of a dataquality framework, its essential components, and how to implement it effectively within your organization. What is a dataquality framework?
In the previous blog , we discussed how Alation provides a platform for data scientists and analysts to complete projects and analysis at speed. In this blog we will discuss how Alation helps minimize risk with active datagovernance. So why are organizations not able to scale governance? Meet Governance Requirements.
Project sponsors seek to empower more and better data-driven decisions and actions throughout their enterprise; they intend to expand their […]. The post Avoid These Mistakes on Your DataWarehouse and BI Projects: Part 3 appeared first on DATAVERSITY.
In this article, we will delve into the concept of data lakes, explore their differences from datawarehouses and relational databases, and discuss the significance of data version control in the context of large-scale data management. Schema Enforcement: Datawarehouses use a “schema-on-write” approach.
“Quality over Quantity” is a phrase we hear regularly in life, but when it comes to the world of data, we often fail to adhere to this rule. DataQuality Monitoring implements quality checks in operational data processes to ensure that the data meets pre-defined standards and business rules.
These data requirements could be satisfied with a strong datagovernance strategy. Governance can — and should — be the responsibility of every data user, though how that’s achieved will depend on the role within the organization. How can data engineers address these challenges directly?

Collecting, storing, and processing large datasets Data engineers are also responsible for collecting, storing, and processing large volumes of data. This involves working with various data storage technologies, such as databases and datawarehouses, and ensuring that the data is easily accessible and can be analyzed efficiently.
Introduction ETL plays a crucial role in Data Management. This process enables organisations to gather data from various sources, transform it into a usable format, and load it into datawarehouses or databases for analysis. Loading The transformed data is loaded into the target destination, such as a datawarehouse.
Suppose you’re in charge of maintaining a large set of data pipelines from cloud storage or streaming data into a datawarehouse. How can you ensure that your data meets expectations after every transformation? That’s where dataquality testing comes in.
Key Takeaways Data Engineering is vital for transforming raw data into actionable insights. Key components include data modelling, warehousing, pipelines, and integration. Effective datagovernance enhances quality and security throughout the data lifecycle. What is Data Engineering?
According to IDC, the size of the global datasphere is projected to reach 163 ZB by 2025, leading to the disparate data sources in legacy systems, new system deployments, and the creation of data lakes and datawarehouses. Most organizations do not utilize the entirety of the data […].
An ERP does not do dataquality very well. CRM’s, likewise, does a poor job of undating data according to consistent standards. Others regard it as a data modeling platform. Still others think of MDM as a merge-and-match exercise, a dataquality tool, or a workflow engine.
we are introducing Alation Anywhere, extending data intelligence directly to the tools in your modern data stack, starting with Tableau. We continue to make deep investments in governance, including new capabilities in the Stewardship Workbench, a core part of the DataGovernance App. Datagovernance at scale.
But, on the back end, data lakes give businesses a common repository to collect and store data, streamlined usage from a single source, and access to the raw data necessary for today’s advanced analytics and artificial intelligence (AI) needs. Irrelevant data. Ungoverned data. Subscribe to Alation's Blog.
For example, data catalogs have evolved to deliver governance capabilities like managing dataquality and data privacy and compliance. It uses metadata and data management tools to organize all data assets within your organization. Ensuring dataquality is made easier as a result.
Machine Learning Data pipelines feed all the necessary data into machine learning algorithms, thereby making this branch of Artificial Intelligence (AI) possible. DataQuality When using a data pipeline, data consistency, quality, and reliability are often greatly improved.
Accounting for the complexities of the AI lifecycle Unfortunately, typical data storage and datagovernance tools fall short in the AI arena when it comes to helping an organization perform the tasks that underline efficient and responsible AI lifecycle management. And that makes sense.
