This thesis concerns the question of data migration and specifically data migration into the Oracle Exadata database environment. A characteristic project of data migration has been designed which is then specified in a form of a data migration operating guideline creation. Suggested process is then tested on a real database migration. A part of this work is also a detailed description of the Oracle Exadata technological solution including an evaluation of its benefits and limitations in a practical usage. Information and feedbacks necessary to accomplish these goals were gained by interviewing specialists on different positions throughout the organisation that have a real experience with the system. This work can also serve as a valuable source of information for projects dealing with data migration, mainly data migration in the Oracle Exadata environment. As a matter of fact, potential future users can find this work very helpful when considering a purchase of the Oracle Exadata system package.
