AWS Schema Conversion Tool Interview Questions
1. What is the AWS Schema Conversion Tool (SCT)?
The AWS Schema Conversion Tool (SCT) is a tool provided by Amazon Web Services (AWS) to assist with database migrations to Amazon Aurora or other databases in the AWS Cloud. It automates much of the process of converting database schemas and migrating data, making it easier and faster to move a database to the cloud.
2. How does the SCT help with database migrations to Amazon Aurora or other databases in the AWS Cloud?
The SCT helps with database migrations to Amazon Aurora or other databases in the AWS Cloud by automating the process of converting database schemas and migrating data. It can analyze the source database schema, identify any issues or incompatibilities, and provide recommendations for how to proceed with the migration. It can also generate the necessary SQL scripts and other required artifacts to facilitate the migration.
3. What types of database schemas can the SCT convert?
The SCT can convert database schemas for a variety of different database engines, including Oracle, Microsoft SQL Server, MySQL, and PostgreSQL.
4. Can the SCT convert stored procedures, functions, and triggers? If so, how does it handle conversion of these database objects?
Yes, the SCT can convert stored procedures, functions, and triggers, as well as other database objects such as views and sequences. It can generate the necessary SQL scripts to recreate these objects in the target database, and can also provide recommendations for any changes that may be required to ensure compatibility with the target database.
5. How does the SCT handle data type conversions during the schema migration process?
The SCT handles data type conversions during the schema migration process by analyzing the source database schema and identifying any data types that are not compatible with the target database. It can then provide recommendations for how to proceed with the migration, such as by modifying the data types or using appropriate data type mapping rules.
6. Can the SCT be used to migrate a database from on-premises to the AWS Cloud, or is it only for migrating between different database engines in the cloud?
Yes, the SCT can be used to migrate a database from on-premises to the AWS Cloud, as well as between different database engines in the cloud.
7. Can the SCT be used to migrate a database from one AWS region to another?
Yes, the SCT can be used to migrate a database from one AWS region to another.
8. Does the SCT support incremental migrations, or does it require a full-database migration each time?
The SCT supports both full-database migrations and incremental migrations, depending on the needs of the user. Incremental migrations allow users to migrate only the data that has changed since the last migration, which can be useful for reducing the time and resources required for the migration process.
9. How does the SCT handle conflicts or errors that may arise during the schema migration process?
The SCT handles conflicts or errors that may arise during the schema migration process by providing recommendations and suggestions for how to resolve these issues. It can also generate SQL scripts that can be used to fix any problems that may be encountered during the migration.
10. Are there any limitations to using the SCT for database migrations?
There are a few limitations to using the SCT for database migrations. For example, it may not be able to fully automate the migration process for certain complex database schemas or configurations, and manual intervention may be required. In addition, the SCT may not support all possible data types or database features, and some changes or modifications to the source database schema may be required to ensure compatibility with the target database.

20. How do you access and use the AWS Schema Conversion Tool?
You can access and use the AWS Schema Conversion Tool by downloading it from the AWS website and installing it on your local machine. Once installed, you can use the SCT to connect to a source database, analyze the schema, and generate the necessary SQL scripts and other artifacts to migrate the database to the target database. You can then use these scripts and artifacts to perform the actual migration process.
