The process of transferring database involves two storage types, formats, or systems – the source and the target. Organizations and companies may want to transfer their databases for a number of reasons, including server or storage equipment replacements, maintenance or upgrades, application migration, website consolidation and data facility relocation. Database migration usually covers all database objects and categories: table definitions, data, indexes, constraints, views, triggers, stored procedures and processes, user accounts and permissions.
Databases can be moved manually or programmatically with the use of complex program often referred to as database converters. Manual technique normally consists of these steps:
- table definitions, indexes and constraints are exported from the source database in form of DDL statements
- these statements are converted into the destination format and imported to the target database (that must exist at this point)
- source data is exported into comma separated values (CSV) files as an intermediate storage
- the exported data must be transformed to comply with the destination format and then loaded into the target database
- views, stored procedures/functions and triggers are extracted from the source database in form of SQL statements and code
- these statements and code are converted according to the syntax of the target DBMS and imported into the database
Shortly after uploading to the new program, the processed data has to be authenticated to determine if the database was properly moved, processed and comes with suitable supports for programs in the new system. It is often advised to run both source and destination database systems at the same time through the entire authentication process to figure out areas of disparity, and forestall data loss or corruption, even after using an advanced database converter.
For giant and complex database migration task, carrying it out programmatically will help you achieve an automatic process flow and reducing human resources on complicated tasks. It is important to choose the appropriate tool known as database converter to transfer the database in the projected time-frame without data loss or data corruption.
Below is the list of basic features which can be provided with the aid of superb database converter:
- All modern releases of source and destination DBMS are supported
- Table definitions, indexes and constraints are converted with all necessary attributes
- Conversion settings must be stored into a profile for next use
- Full Unicode support
- Customization of types mapping, attributes of database objects and conversion rules
- Command line support
- Comprehensive documentation and 24/7 support service
There is also a range of software organizations that provide dedicated solutions to automate database migration. Intelligent Converters is one of this organizations that are delivering high-quality services in the field of database conversion, migration and synchronization from 2001. They develop a variety of database converters for a lot of well-known database management systems like PostgreSQL, MySQL, Oracle, SQL Server, Azure SQL, Microsoft Access, FoxPro and SQLite.
