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.

Database Evaluation

Database evaluation covers the compatibility analysis, target database recommendation, workload evaluation, and migration risk identification on the object collection of the source database to identify the feasibility and risks of migrating data from the source database to the target database.

Schema Migration

Based on the selected target database and source database, equivalent syntax conversion and migration are performed on the collected objects, including DDL, DML, and PL/SQL objects.

Source Database Profiling

Source database profiling uses massive service scenarios as samples and key database metrics as features for training to abstract the database information, providing the data basis for further accurate and quick analysis of important information such as application scenarios and user operation habits of the source database.

Compatibility Analysis

Compatibility analysis analyzes and evaluates the convertibility of the collected objects in the target database, and provides the analysis result based on the selected source and target databases and full syntax tree analysis of the source database.
