The document provides an extensive overview of database implementation and maintenance, focusing on MySQL. It covers physical design, performance optimization, and access control alongside aspects of data integrity, recovery, and high availability architectures. Best practices for backup and recovery techniques are also discussed.

1. PART 1: Database Implementation
Overview of the versatile tasks of a DBA.
Physical design and implementation of MySQL objects:
Object definition: decision rules
Possibilities for the implementation of a logical design: datatypes, primary/foreign keys,
indexes, triggers, auto-incremented columns, LOBs, views, storage engines, partitioning, ...
storage considerations: files, directories, disks
Implementing a test environment & preparing for production: DDL (create/alter/drop) &
MySQL-specific extensions and deviations to the SQL standard
Prepare the database for performance analysis
Access control to MySQL objects:
Defining users; managing passwords;
Scenarios for efficient security management and auditing requirements
The MySQL data dictionary
The MySQL database
The object catalog: the INFORMATION_SCHEMA database
Displaying system information and metadata
PART 2: Database maintenance, integrity control, performance optimization
Maintenance considerations:
Shutting down and restarting the server
Configuring data caching and query caching
Benchmarking, profiling, capacity planning

2. Utilities: export/import of external data; defragmentation; check and repair
(Re) partitioning of tables; moving data to other disks; changing the engine
Use of data compression
Hardware-tuning of the MySQL server
Scaling and high availability architectures
Data integrity, locking and transactions
PART 3: Database recovery
Logging and replication
Backup and recovery techniques:
Copying databases to another machine
Point-in-time recovery and disaster recovery: best practices
