Solana Accounts vs Databases

The article explains that Solana's account model parallels database concepts, where an account is like a row, a public key is like a primary key, and program logic acts as a schema. However, the key difference is that data on Solana lives on a shared, decentralized network rather than a single server, with ownership and permissions dictating who can modify it. Ultimately, Solana requires thinking in terms of ownership and state rather than traditional database tables.

If you know databases, Solana can feel familiar and strange at the same time. A database row becomes an account, a primary key becomes a public key or PDA, and a schema becomes program logic. The big shift is this: data lives on a shared network, not one company server. The program decides what the data means, and only the right signer can change it. That is why Solana asks you to think less about tables and more about ownership, permissions, and state. The table and the solana address output make the idea easier to see at a glance. On Solana, identity and data are tied to accounts, and accounts behave very differently from rows in a normal database.
