Due to advancements in technology, huge volumes of data need to be stored to collect information about the components. Businesses have to keep records of everything to use for future purposes in case of verification or other situations. Thus, they employ various techniques and data science specialists to execute the job. One of the best techniques for a huge collection of data is data lakes. visit here for more details on Data Science Training in Pune
What are data lakes?
Data lakes serve for the storage of a large volume of data especially in the native format to be available whenever required. There are different types of data storage in the data lakes. Some of these are discussed here.
- Operational data works for the storage of finances, collection of inventory, and number of sales generated in all the previous cases.
- Auto-generated data helps to store logs of the software and data of the other devices operated for the ambition.
- Human-generated data is related to social activities on the internet such as emails, social media details, web content.
Different types of data storage helps to easily locate your interesting facts in the high volumes of data within less time.
Layering :
You might think that data storage is only in a single form but in fact, it is not the case. For the division of data and better understanding, details are divided into various layers to separate it whenever required. Here are some layers of data storage.
- Raw
- Cleansed
- Application
These are the fundamental layers of the data storage in the data lakes. Some of the optional layers may be present that are mostly Standardized and Sandbox. Before moving to data storage, you have to understand each layer format and implement it in your lakes.

Important components :
Here are some important components of data lakes.
Security:
As the safety of the whole details about the contact numbers and other information of clients, security of data lake is an integral component. Data lakes are not much secured, unlike the other data. So to prevent attacks from the other hackers, you should implement basic security techniques and improve them for conservation.
Governance:
Control of various operations in the data lakes is necessary to get the expected results. In some cases, you have to demonstrate the performance of the data lake while storing the information. Governance and effective control makes you feel your data more efficient and secure.
Metadata :
It includes important information regarding reloading time, storage of the data, aim to store the data, and strategies to apply in the future. As all the information in the metadata is crucial to the data lakes, we can use it to derive many results.
Stewardship:
Includes the dependency on either the role of a team or the user.
Master Data :
One of the most important elements of the data lake is master data that needs to be either stored or referenced in many other situations. Know more about Data Science Training in Chennai
Archive:
It holds all the records related to issues while storing data and management of data.
OffData:
Used in case of some type of time-consuming data storage.
Orchestration and ELT processes :
To process the data from various layers, you require this component.
