A dataset is defined as a collection of data related to a specific topic, which can include various types of information like numbers, text, images, and more, stored in formats such as CSV or JSON. Differentiating between datasets and databases, datasets are often static collections used for analysis, while databases are structured systems for managing large data volumes with complex functionalities. Various types of datasets exist, categorized by data type, structure, and statistical or machine learning applications. Datasets offer numerous benefits, such as improved decision-making, enhanced user experience, and cost savings by enabling businesses to analyze trends, customer behaviors, and operational efficiencies. Creating datasets can involve custom data parsers or purchasing pre-existing datasets, with providers like Bright Data offering tools and datasets for various uses, including price comparison, social media monitoring, and recruitment. An example given is an avocado prices dataset, which tracks sales data across U.S. cities, illustrating how datasets can be used to monitor trends and economic indicators.
