Chronicle Cache: Memory-Indexed E-commerce Data

This project, 'Chronicle Cache,' leverages inspiration from the nonlinear storytelling of 'Memento' and the thematic exploration of shifting realities in 'Nightfall' (specifically, the idea of perceiving information in fragmented ways) combined with the practical application of e-commerce pricing data. Imagine a scraper project that captures e-commerce prices, but instead of a simple timestamp, each data entry is associated with a 'memory shard' – a specific snapshot of a product's price at a given point in time. The core database management system will not only store this pricing data but also allow users to query it based on these 'memory shards.'

Story/Concept: In the world of e-commerce, price fluctuates constantly. Understanding the -why- and -when- of these changes is crucial for competitive analysis, historical trend identification, and even detecting potential market manipulation. 'Chronicle Cache' treats each price point as a fragmented memory. A user might want to know 'What was the price of this item -just before- the major holiday sale last year?' or 'How did the price of this competitor's product evolve -during- the summer discount period?' The database is structured to answer these context-dependent historical queries efficiently.

How it Works:

1. Data Ingestion: An e-commerce scraper (either pre-built or developed as part of the project) collects product pricing data. Crucially, instead of just a timestamp, each data point is tagged with a unique 'memory ID' and a timestamp. The 'memory ID' could be as simple as a sequential number, or more complex, representing a specific event (e.g., 'BlackFriday2023_shard1').
2. Database Schema: A relational database (like PostgreSQL or SQLite for simplicity) will be used. Key tables would include:
- `Products`: `product_id`, `name`, `url`, etc.
- `PriceHistory`: `price_id`, `product_id`, `price`, `memory_id`, `timestamp`.
- `MemoryContext`: `memory_id`, `description` (e.g., 'Pre-holiday sale', 'Competitor launch period').
3. Querying: Users can query the database using natural language-like structures or specific APIs that allow them to specify the 'memory' they are interested in. For example:
- `SELECT price FROM PriceHistory WHERE product_id = X AND memory_id = 'BlackFriday2023_shard1';`
- A more advanced query could involve filtering by date ranges within a specific 'memory' or comparing price evolution across different 'memories' for the same product.

Niche: Focusing on temporal-contextualized e-commerce data is a specific niche within broader e-commerce data analysis.

Low-Cost: Can be implemented using free or low-cost database solutions and readily available Python scraping libraries.

High Earning Potential: Offers valuable insights for e-commerce businesses, marketers, and financial analysts looking for competitive intelligence and historical trend analysis. Monetization could involve SaaS subscriptions for access to the database or API, or selling tailored reports.
