What exactly is a columnar database used for?
The answer to what is columnar database is quite simple: it's a database which stores and queries data in columns as opposed to rows. This is especially useful for analytical workloads, as queries typically filter on specific fields in a large number of records, such as millions or billions. If only certain columns are used in a query, processing the rest may be unnecessary resulting in faster query response time. Column-oriented systems are typically employed where the primary use is a dashboard, reporting, data warehouse and big data analysis. Datalance can assist in planning an environment by evaluating the architecture, according to workload needs and anticipated data growth.
Which option should I choose for storing and analyzing business data?
Consider the data you're working with and what you'd like to do with that data when you consider data lake vs warehouse. A data lake can be helpful when you have a lot of unstructured or diverse data that could be useful for other purposes at a later time. Structured reporting and regular business analysis, it is better to use a warehouse. Some vendors ultimately employ both. It's not always the latest technology, it should be the right technology for your data, analytics requirements, budget and team capabilities.
How do I choose reliable data mining support for my business?
