The idea of learning seven databases in seven weeks is, as acknowledged by the authors themselves, a pedagogical metaphor rather than a strict timeline. In 2025, the practicality of this goal depends heavily on the learner's background and objectives:
For a Beginner: Attempting to learn 7 databases in 7 weeks for a complete beginner in 2025 is still highly ambitious and likely superficial. While the book provides a good starting point, truly grasping each paradigm requires more time for experimentation, projects, and understanding operational nuances. It's more realistic to spread the learning over several months.
For an Experienced Developer/Architect: For someone with a strong tunisia phone number list background in one database type (e.g., relational) looking to broaden their horizons, the "seven weeks" concept can be a valuable, intensive sprint. The goal is to gain conceptual understanding and familiarity, not expertise, in each.
The "Install Locally" vs. "Cloud" Challenge: In 2025, manually installing and managing 7 different database technologies locally might even be more effort than in 2012, given the complexity of modern versions. Using managed cloud services (e.g., spinning up a MongoDB Atlas cluster, an AWS RDS PostgreSQL instance, a Neo4j AuraDB instance) would be a much more efficient and realistic way to get hands-on experience, although it incurs cloud costs. This changes the "how-to" aspect of the book.
