Course Introduction：SQL database migration requires choosing the right tools, making preparations, and adopting reasonable strategies. Recommended tools include AWSDMS for cloud migration, SSMA for SQLServer ecological migration, MySQLWorkbench for migration to MySQL, Flyway and Liquibase for version control. Before migration, you must evaluate the structure and data volume, check compatibility, backup the source library, and verify in the test environment. The migration strategy can choose full incremental synchronization, phased migration, downtime migration or double write mechanisms. Common problems include data inconsistency, performance bottlenecks, structural conversion failures and permission issues, which need to be dealt with in advance.

Course Introduction：During Laravel development, it is often necessary to add virtual columns to the model to handle complex data logic.

This library not only simplifies the management of virtual columns, but also improves the maintainability and efficiency of the code.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
