Data is collected from multiple sources, and moved into the data lake in its original format. This process allows you to scale to data of any size, while saving time of defining data structures, schema, and transformations.</p> \n<h3>Securely store and catalog data</h3> \n<p>Data lakes allow you to store relational data like operational databases and data from line of business applications, and non-relational data like mobile apps, IoT devices, and social media. They also give you the ability to understand what data is in the lake through crawling, cataloging, and indexing of data. Finally, data must be secured to ensure your data assets are protected.</p> \n<h3>Analytics</h3> \n<p>Data lakes allow various roles in your organization like data scientists, data developers, and business analysts to access data with their choice of analytic tools and frameworks. This includes open source frameworks such as <a href=\"https://aws.amazon.com/what-is/hadoop/\">Apache Hadoop</a>, <a href=\"https://aws.amazon.com/what-is/presto/\">Presto</a>, and <a href=\"https://aws.amazon.com/what-is/apache-spark/\">Apache Spark</a>, and commercial offerings from data warehouse and business intelligence vendors. Data lakes allow you to run analytics without the need to move your data to a separate analytics system.</p> \n<p><a href=\"https://aws.amazon.com/what-is/data-analytics/\" tabindex=\"0\">Read about Data Analytics »</a></p> \n<h3>Machine Learning</h3> \n<p>Data lakes will allow organizations to generate different types of insights including reporting on historical data, and doing machine learning where models are built to forecast likely outcomes, and suggest a range of prescribed actions to achieve the optimal result.</p> \n<p><a href=\"https://aws.amazon.com/what-is/machine-learning/\" tabindex=\"0\">Read about Machine Learning »</a></p>","id":"seo-faq-pairs#what-are-the-essential-elements-of-a-data-lake-and-analytics-solution","customSort":"3"},"metadata":{"tags":[{"id":"seo-faq-pairs#faq-collections#data-lake","name":"data-lake","namespaceId":"seo-faq-pairs#faq-collections","description":"<p>data-lake</p>","metadata":{}}]}},{"fields":{"faqQuestion":"How does a data warehouse compare to a data lake?","faqAnswer":"<div> \n <p>Depending on the requirements, a typical organization will require both a data warehouse and a data lake as they serve different needs, and use cases.</p> \n <p>A data warehouse is a database optimized to analyze relational data coming from transactional systems and line of business applications. The data structure, and schema are defined in advance to optimize for fast SQL queries, where the results are typically used for operational reporting and analysis. Data is cleaned, enriched, and transformed so it can act as the “single source of truth” that users can trust.</p> \n <p><a href=\"https://aws.amazon.com/what-is/data-warehouse/\" tabindex=\"0\">Read about data warehouses »</a></p> \n <p>A data lake is different, because it stores relational data from line of business applications, and non-relational data from mobile apps, IoT devices, and social media. The structure of the data or schema is not defined when data is captured. This means you can store all of your data without careful design or the need to know what questions you might need answers for in the future. Different types of analytics on your data like SQL queries, big data analytics, full text search, real-time analytics, and machine learning can be used to uncover insights.</p> \n <p>As organizations with data warehouses see the benefits of data lakes, they are evolving their warehouse to include data lakes, and enable diverse query capabilities, data science use-cases, and advanced capabilities for discovering new information models. Gartner names this evolution the “Data Management Solution for Analytics” or “<a href=\"https://www.gartner.com/doc/3614317/magic-quadrant-data-management-solutions\" target=\"_blank\">DMSA</a>.”</p> \n <p>For an in-depth comparison between data lakes and data warehouses, visit our dedicated <a href=\"https://aws.amazon.com/compare/the-difference-between-a-data-warehouse-data-lake-and-data-mart/\">comparison page for data lakes vs data warehouses</a>.</p> \n</div>","id":"seo-faq-pairs#how-does-a-data-warehouse-compare-to-a-data-lake","customSort":"4"},"metadata":{"tags":[{"id":"seo-faq-pairs#faq-collections#data-lake","name":"data-lake","namespaceId":"seo-faq-pairs#faq-collections","description":"<p>data-lake</p>","metadata":{}}]}},{"fields":{"faqQuestion":" What is the value of data lakes?","faqAnswer":"<p>The ability to harness more data, from more sources, in less time, and empowering users to collaborate and analyze data in different ways leads to better, faster decision making. Examples where Data lakes have added value include:</p> \n<h3>Improved customer interactions</h3> \n<p>A Data lake can combine customer data from a CRM platform with social media analytics, a marketing platform that includes buying history, and incident tickets to empower the business to understand the most profitable customer cohort, the cause of customer churn, and the promotions or rewards that will increase loyalty.</p> \n<h3>Improve R&D innovation choices</h3> \n<p>A data lake can help your R&D teams test their hypothesis, refine assumptions, and assess results—such as choosing the right materials in your product design resulting in faster performance, doing genomic research leading to more effective medication, or understanding the willingness of customers to pay for different attributes.</p> \n<h3>Increase operational efficiencies</h3> \n<p>The Internet of Things (IoT) introduces more ways to collect data on processes like manufacturing, with real-time data coming from internet connected devices.
