+# Override Table Name For Prisma Model
+
+When defining your Prisma schema, you'll add models to your
+`prisma/schema.prisma` file that look something like this:
+
+```
+model Book {
+  id               BigInt   @id @default(autoincrement()) @db.BigInt
+  title            String
+  author           String
+  publication_year Int
+  created_at       DateTime @default(now())
+  updated_at       DateTime @updatedAt
+}
+```
+
+The prisma client (ORM-layer) that gets generated will have a `Book` type and
+you'll be able to reference the model to, for instance, create a record with
+`prisma.book.create(...)`. Both of these things are derived from the model
+name: `Book`.
+
+The other thing that is derived from the model name is the name given to the
+underlying database table. So you end up with a table called `Book`. You may,
+however, prefer a table naming convention where this one would be named `books`
+(snake_case and pluralized).
+
+To achieve that, you have to manually override the table name with [the `@@map`
+directive](https://www.prisma.io/docs/orm/reference/prisma-schema-reference#map-1).
+Add it toward the bottom of the model like so:
+
+```
+model Book {
+  id               BigInt   @id @default(autoincrement()) @db.BigInt
+  title            String
+  author           String
+  publication_year Int
+  created_at       DateTime @default(now())
+  updated_at       DateTime @updatedAt
+
+  @@map("books")
+}
+```
