Querying Data
Querying data refers to the process of retrieving specific information from a database or dataset using a query language. In data science, querying data is an essential step in the data analysis process as it allows analysts to extract relevant information from large and complex datasets. Querying data involves writing queries that specify the criteria for selecting data from a database or dataset. These queries can be simple or complex, depending on the nature of the data and the questions being asked. Querying data can be done using various query languages such as SQL, NoSQL, and graph query languages. The results of a query can be used to generate reports, visualizations, or to perform further analysis.
