Basic Concepts
Source Database
Source database is the database to be migrated.
Target Database
Target database is the database that receives the data migrated from the source database. It can be a Huawei Cloud GaussDB or RDS database.
Compatibility Analysis
The entire syntax tree of the source database is analyzed, so you can learn what differences there are in the syntaxes of the source and target databases. You can learn how compatible the two databases are and what the expected migration success rate will be for the objects migrated.
Database Evaluation
Database evaluation includes a syntax compatibility analysis, target database recommendation, syntax reconstruction workload evaluation, and migration risk identification for the object collection of the source database. The database evaluation allows you to identify how feasible the migration will be and what risks may be involved.
Schema Migration
The database objects (tables, indexes, views, stored procedures, and functions) are converted to match the syntax of the target database. These converted objects are then added to the target database.
Source Database Profiling
The metadata of the source database is extracted and analyzed in multiple ways, such as the number of objects, type distribution, and complexity, to abstract the database information. This provides data basis for further accurate and quick analysis of important information, such as the application scenarios and user operation habits of the source database.
