KS DB Merge Tools

KS DB Merge Tools is an easy to use diff & merge tool for MySQL, MariaDB, Oracle Database, SQL Server, PostgreSQL, SQLite, MS Access and Cross-DBMS databases allowing to compare and sync both schema and data. Starting with a schema changes summary, results can be narrowed down to object lists of particular object type (table definitions, views, etc.), and then down to definition of particular object. Data changes can be retrieved as a high-level list of changes totals across all tables in the database, each total row count can be observed as a side-by-side list of rows for the given table, each changed row can be analyzed for changes in each column. Various diff results provide quick filters to show only new/changed/new+changed items (schema objects or table data rows), ability to select required changed items and generate scripts to apply these changes to the other side database. This script can be executed immediately or saved for future use.

Liquibase

One area hasn’t benefited from the DevOps movement as much: The database change process. It’s time to bring CI/CD to the database. Application release technology has come a long way in the past several years. It used to take weeks or even months to release new software. Now that organizations have adopted new workflows and processes, the time it takes to complete a release has been reduced to days and even hours. Database schema migrations are an essential task for every software project. There are several different reasons why updates to the database are required. New features require new attributes in existing tables or entirely new tables. Bug fixes may lead to changes in names or data types in the database. Performance issues that require additional indexes in the database. Even in organizations that have adopted DevOps, manual rework is the norm when it comes to database schema and stored procedure changes.
