Knowing the Internals, Who Needs SQL Server Anyway?
You're stuck on a remote island with just a laptop and your main database .MDF file. The boss calls and asks you to retrieve some data, but alas, you forgot to install SQL Server on your laptop. Luckily you have a HEX editor by your side!
In this level 500 deep dive session we will go into the intimate details of the MDF file format. Think using DBCC Page is pushing it? Think again! As a learning experiment, I've created an open source parser for MDF files, called OrcaMDF. Using the OrcaMDF parser I'll go through the primary storage structures, how to parse page headers, boot pages, internal system tables, data & index records, b-tree structures as well as the supporting IAM, GAM, SGAM & PFS pages.
Has your database suffered an unrecoverable disk corruption? This session might just be your way out! Using a corrupt & unattachable MDF file, I'll demo how to recover as much data as possible. This session is not for the faint of heart, there will be bits & bytes.
