Big Data: Data Lake vs Data Warehouse
It can be a minefield to deal with big data! The volume of data generated on a daily basis is rising exponentially and the preservation and security of this information is of utmost importance as our customers are only too aware. As more businesses find themselves accruing large quantities of data, it is something that must be seriously considered to figure out the most business-appropriate way to store their information.

An centralised repository of storage is a Data Warehouse:
Data sources, business processes and inclusion/exclusion protocols must be defined as part of the initial set-up of a data warehouse. As a general rule, only if a need has been established can data be included in the warehouse.
The data is stored, archived and organised in a pre-defined way inside a data warehouse.
Advantages:
Disadvantages:
A Data Lake is an unstructured, single-store repository.
In comparison to a data warehouse, the data is loaded unstructured and unorganised inside a data lake. Until it reaches the repository, it is not evaluated or processed; it can be loaded in its roughest state. In a data lake, there can be information that is never used because data can be accepted from all sources and in all formats.
The configuration (creation of the schema) takes place as and when the data is required within a date lake.
Advantages:
Disadvantages:
The Data Swamp Avoided:
If a Data Lake is not adequately managed, the possibility of it being a data swamp is present. This occurs when the knowledge is lost or useless and unavailable to the users inside the lake. It is important to have a plan, vision and target for the data lake.
