🔍 𝗕𝗲𝘀𝘁 𝗣𝗿𝗮𝗰𝘁𝗶𝗰𝗲: 𝗶𝗻𝘁 𝘃𝘀 𝗚𝗨𝗜𝗗 𝗳𝗼𝗿 𝗣𝗿𝗶𝗺𝗮𝗿𝘆 𝗞𝗲𝘆𝘀 𝗶𝗻 𝗘𝗻𝘁𝗶𝘁𝘆 𝗙𝗿𝗮𝗺𝗲𝘄𝗼𝗿𝗸 𝗖𝗼𝗿𝗲

As part of my 𝗽𝗲𝗿𝘀𝗼𝗻𝗮𝗹 𝗽𝗿𝗼𝗷𝗲𝗰𝘁 – 𝗝𝗼𝗯 𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻 𝗧𝗿𝗮𝗰𝗸𝗲𝗿, I researched which type of primary key is best for database models in .NET Core.

✅ 𝗶𝗻𝘁 (𝗜𝗻𝘁𝗲𝗴𝗲𝗿)

public int Id { get; set; }

• ✅ Better performance (faster indexing, smaller size)

• ✅ Human-readable, cleaner in URLs (/resume/25)

• ✅ Ideal for small/medium apps with a single DB

✅ 𝗚𝗨𝗜𝗗 (𝗚𝗹𝗼𝗯𝗮𝗹𝗹𝘆 𝗨𝗻𝗶𝗾𝘂𝗲 𝗜𝗱𝗲𝗻𝘁𝗶𝗳𝗶𝗲𝗿)

public Guid Id { get; set; }

• ✅ Unique across systems (great for microservices)

• ✅ Harder to guess in URLs (/resume/7e0f-...)

• ✅ Better security for public-facing routes

For this project, I'm using int for IDs (like ResumeFileId, JobApplicationId) since it's simple, performant, and fits well for apps using a single database.
