Historical Data on Data Boutique

Historical data allows you to access all past data collections of a website from a specific vendor. The depth of historical data available depends on how long the vendor has been sharing their data on Data Boutique. When you purchase historical data, you receive the entire available history, giving you a comprehensive view of the data over time.

Accessing Historical Data

Data Boutique offers multiple options for accessing historical data, each with different levels of detail depending on your requirements:

  • Monthly Detail: Available for all datasets with historical data, the monthly detail includes one data collection per month. This snapshot is typically taken on the last day of each month or the closest valid date.
  • Weekly Detail: Available for datasets with daily or weekly updates, the weekly detail includes one collection per week, usually from the last day of the week or the closest date available.
  • Daily Detail: For datasets with daily updates, the daily detail provides all available data collections, giving you every snapshot recorded on Data Boutique.

This range of options allows you to choose the level of detail that best suits your analysis needs, from high-level monthly overviews to detailed daily records.

Cost of Historical Data

The cost of historical data is calculated based on the number of snapshots included, with discounts applied according to the chosen frequency. The base price is set by the unit price of the dataset, multiplied by the number of snapshots, with volume discounts for larger quantities:

  • Monthly Detail: No discount applied. You pay the unit price for each monthly snapshot.
  • Weekly Detail: A 20% discount applies to the total, as this option includes more frequent snapshots.
  • Daily Detail: A 50% discount applies for daily snapshots, providing the most granular level of detail.
Example Calculation

Let’s say a dataset is priced at 10 EUR per snapshot and has been available on Data Boutique for a full year:

  • Monthly Detail: 12 snapshots (one per month) x 10 EUR = 120 EUR
  • Weekly Detail: 52 snapshots (one per week) x 10 EUR, minus 20% discount = 416 EUR
  • Daily Detail: 365 snapshots (one per day) x 10 EUR, minus 50% discount = 1,825 EUR

Handling Missing Values

In some cases, a dataset’s historical data may have missing snapshots. Each historical dataset includes a completeness rate, indicating the percentage of snapshots available (with 100% meaning all snapshots are present). If any snapshots are missing, they will not be billed to the customer, ensuring fair pricing based on the data actually provided.

In Summary

  • Historical Data Options: Monthly, weekly, or daily snapshots, depending on dataset update frequency.
  • Pricing and Discounts: The cost depends on the number of snapshots, with discounts for weekly (20%) and daily (50%) options.
  • Completeness Rate: Missing snapshots are noted in the completeness rate and are not billed to the customer.

Historical data offers a valuable way to analyze trends over time, helping you make informed, data-driven decisions with confidence in the data’s depth and quality.
