As we all know, Taobao Pinduoduo is the mainstream e-commerce platform in my country, and there are a lot of product data on it. Many merchants will access their product data through API, and charge according to the number of API calls. Third-party data companies provide e-commerce data interface APIs to collect real-time data. However, there is a large amount of cached data on their servers that has been ignored by everyone. The role and value of this huge batch of cached data is very large. They save the time and cost of calling the API, and call it directly from the server, which is very cost-effective.
For the delivery of cached product data on large e-commerce platforms such as Pinduoduo and Taobao, how to deliver smoothly is the key. Here are some formats that may be suitable for caching product data:
-
JSON: JSON (JavaScript Object Notation) is a lightweight data exchange format that is easy to read and write, and capable of describing both simple and complex data structures. When caching product data, the data can be converted into JSON format and then stored in the cache.
-
XML: XML (Extensible Markup Language) is a markup language that can be used to describe the structure of data. XML can be used to store and transmit data, and has wide compatibility. However, XML is more complex than JSON and slower to parse. It consists of plain text files where each line represents a record and each field is separated by a comma. SQLite supports SQL language, can perform complex data query, and has high performance. If your product data structure is simple, JSON and CSV may be good choices. If your data structure is relatively complex, or you need to perform complex data queries, SQLite may be more suitable.
