Preparing a consistent schema

I’m designing the SQL schema and seed data around the earlier fictional records, while reconciling copy statuses with active loans and reservations. I’m also preserving historical context where dates and statuses no longer align.

Reconciling snapshot data

I’m fixing the dataset around September 21, 2026, seeding five core entities plus extra copies and loans. I’m also choosing safe updates and deletions that preserve referential integrity while demonstrating business operations clearly.

Checked PostgreSQL environment, lab file, and package availability

Building the final artifact

I’m prioritizing the document structure, source references, database examples, and consistent rendering. I’ll keep the report organized with headings, tables, code sections, references, and a navigable contents section.

Structuring report content

I’m preserving the requested headings, theory topics, questions, SQL classifications, and practical sections while omitting descriptive task instructions. I’ll keep the supplied wording intact and present selected subsections in bold.

Clarifying subsection presentation

I’m keeping each practical subsection as a bold numbered prompt, followed by its answer, while removing only introductory instructions. I’ll also distinguish a generated schema diagram from any genuine database-interface screenshot.

Finalizing the report

I’m assembling the complete report and SQL materials with consistent formatting, precise source references, navigable contents, and clearly separated practical answers. I’ll avoid presenting generated visuals as genuine interface screenshots.

Finalizing formatting details

I’m applying a formal academic layout: A4, Times New Roman, 14-point body text, 1.5 spacing, standard indents, centered page numbers, structured headings, compact code, and a clear monochrome schema diagram.

Applying report formatting

I’m using formal academic styling throughout: A4 pages, Times New Roman, structured headings, compact SQL excerpts, a monochrome schema diagram, Mermaid support, source notes, and clear disclosure of what was actually tested.
