Data warehouse vs. data lake assignment help

This leads to the data warehouse vs. data lake question when to use which one and how they compare to each other.

They differ in their purpose, structure, types of data they store, where the data comes from and who has access to it.

In general, data comes into these repositories from systems that generate data — CRM, ERP, HR, financial applications and other sources. AI systems are often built with data records in mind. These records can be used in various ways to help organize, manage & analyze business data. It is then sent to a data storage area for further use
Once all the data from the disparate business applications is collated onto one data platform, it can be used in data analytics tools to identify trends or deliver insights to help make business decisions.
What is a data lake?
Data lakes can store lots of data from many different sources in a single repository. This benefits a company because, for example, it provides insurance against data loss if one encounter is to happen. Along with this benefit is the ability to pull out usage information about particular types of data that will work the best into your business environment.. Each stored data element is tagged with a unique identifier and metadata so it can be queried more easily when needed. Data lakes have no predefined schema, and analysts can apply the schema after the ingestion process is complete.
Data lakes have become a popular architecture for storing and processing data across numerous solutions. Across vendors, the amount of data collected continues to grow, which is a major part of why companies want to use these solutions.
What is a data warehouse?
A data warehouse is a repository for data collected and generated by business applications for a predetermined purpose. It can be used to store all kinds of information gathered in different formats to help support decision-making. Data warehouses apply a predefined schema to data before storage, and data must be cleaned and organized before being stored in this repository.
Because data stored in a data warehouse is already processed, it is easier for high-level analysis. BI tools can easily access and use the processed data from a data warehouse, making it simpler for non-data professionals to use data warehouses.
Data warehouse vs. data lake
It’s typically not advisable to just go straight for the data lake when you’ve got hundreds of terabytes of operational data that needs to be easily accessible for business analysis. A data warehouse would offer a more scalable & cost-effective solution.Data warehouses often serve as the single source of truth because these platforms store historical data that has been cleansed and categorized.
While data warehouses retain massive amounts of data from operational systems, a data lake stores data from more sources. A data lake platform is an amalgamation of raw data assets that come from companies’ operational systems and other sources; often including both internal and external ones
Because the data within data lakes may be uncurated and can originate from sources outside of the company’s operational systems, Business analytics users are trying to find ways to make this process easier. Business analytics experts are, however, still in charge of data lakes.
To remember the difference between a data warehouse and data lake, picture actual warehouses and lakes: Warehouses store curated goods from specific sources, whereas a lake is fed from rivers, streams and other unfiltered sources of water.
Data warehouse vendors include AWS, Cloudera, IBM, Google, Microsoft, Oracle, Data lakes are an option for many different management providers. Teradata, SAP, Snowflake and SnapLogic are just a few of the many options.
Which is right for me?
Deciding on a data warehouse vs. a data lake depends mostly on how you plan to use your data.
Some people think data warehouses are too complex and difficult to set up. However, they actually make it easy for non-technical employees with less knowledge in the field to analyze data and provide insights easily.Not only is it easier for business and data analysts to input data into BI and analytics tools, the design of data warehouses makes it easy for different teams and departments to access the data from the repository. Data warehouse architecture is important to break down data siloes across enterprise teams by sharing knowledge about your business & market.
A data lake approach is popular for organizations that ingest vast amounts of data in a constant stream from high-volume sources. Ingestion to a data lake is relatively uncomplicated because it can store raw data. The unstructured data is more difficult to navigate than the processed data of a data warehouse. Data lakes allow data scientists to use various models and queries for deep analysis, as well as predictive modeling. This flexibility also makes data lakes popular for enterprises that have data on hand for future analysis.
There are also some cases where combining a data lake and data warehouse may be best. Enterprises may have data scientists explore the potential of elements in a data lake for changing marketing strategies and to improve industry-specific services and products for future progress.
