## SQL Schema (Generated)
|
|
|
|
```sql
|
|
-- Books table
|
|
CREATE TABLE "Book" (
|
|
"id" SERIAL PRIMARY KEY,
|
|
"title" VARCHAR(500) NOT NULL,
|
|
"author" VARCHAR(500),
|
|
"totalPages" INTEGER NOT NULL,
|
|
"coverUrl" VARCHAR(1000),
|
|
"deadlineDate" DATE NOT NULL,
|
|
"isPrimary" BOOLEAN NOT NULL DEFAULT false,
|
|
"status" VARCHAR(50) NOT NULL DEFAULT 'reading',
|
|
"createdAt" TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
|
|
"updatedAt" TIMESTAMP NOT NULL
|
|
);
|
|
|
|
-- Indexes for Books
|
|
CREATE INDEX "Book_deadlineDate_idx" ON "Book"("deadlineDate");
|
|
CREATE INDEX "Book_status_idx" ON "Book"("status");
|
|
|
|
-- Reading Logs table
|
|
CREATE TABLE "ReadingLog" (
|
|
"id" SERIAL PRIMARY KEY,
|
|
"bookId" INTEGER NOT NULL,
|
|
"logDate" DATE NOT NULL,
|
|
"currentPage" INTEGER NOT NULL,
|
|
"createdAt" TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
|
|
"updatedAt" TIMESTAMP NOT NULL,
|
|
CONSTRAINT "ReadingLog_book_fkey" FOREIGN KEY ("bookId") REFERENCES "Book"("id") ON DELETE CASCADE
|
|
);
|
|
|
|
-- Unique constraint: one log per book per day
|
|
CREATE UNIQUE INDEX "ReadingLog_bookId_logDate_key" ON "ReadingLog"("bookId", "logDate");
|
|
|
|
-- Indexes for ReadingLog
|
|
CREATE INDEX "ReadingLog_bookId_idx" ON "ReadingLog"("bookId");
|
|
CREATE INDEX "ReadingLog_logDate_idx" ON "ReadingLog"("logDate");
|
|
```
|
|
|
|
**Performance Considerations:**
|
|
- Indexes on `deadlineDate` and `status` for filtering active books
|
|
- Composite unique index on `(bookId, logDate)` prevents duplicate logs and optimizes queries
|
|
- Index on `logDate` for date range queries (7-day rolling average)
|
|
- Cascade delete ensures orphaned logs don't persist when book is deleted
