Neo4j has been successfully integrated into Kale Yazılım's software stack for nearly three years, resulting in significant improvements. The company uses Neo4j to analyze Turkish citizen data and identify seniors without nearby relatives, a task that was previously impossible with SQL. Cypher, Neo4j's graph query language, is cited as a key reason for the choice of Neo4j, along with its ease of use and speed. A notable project involves compiling ancestral trees from census data in real-time using Neo4j, which has been integrated with a relational database to ensure up-to-date data. The expert notes that graph databases are on the rise due to the growing amount of global data, and that understanding relationships between data points is crucial for managing valuable information. Ultimately, the use of graph databases will become a standard part of every system.
