Marriott, a large hospitality company, was facing performance issues with their pricing engine application due to its relational database. They needed faster and more accurate results for their 4,500 locations across the country. To address this issue, they implemented Neo4j, a graph database, which allowed them to process data much faster, reducing processing time from over four minutes to just 13 seconds. The implementation provided several benefits, including improved performance, increased adoption of the system due to better adoption rates, and reduced hardware requirements, resulting in a 50% reduction in infrastructure costs. Additionally, Marriott was able to maintain their existing relational database as a backup solution while leveraging Neo4j for faster data processing. The experience with Neo4j has allowed Marriott to explore other use cases within their company and adopt the technology without anxiety, enabling them to look for new opportunities to leverage its capabilities.
