Data migration process deals with databases: to put it simply, data from one database is transferred to another one.
You might have already heard about Extract, Transform, Load (ETL) concept which is applied here:
However, this process is not that trivial as it might seem at first sight. Why? You might encounter certain difficulties while doing data migration:
This is where a professional service provider comes to rescue your project!
Sometimes it can be done manually. Alternatively, a special script can be written to automate this process. This script can be tuned so that the migration process can be done on a regular basis, not just single-time.
As for automatic data transfer, most software solutions providers utilize two methods to achieve this. Let’s look through them.
Which way to choose depends on many factors – kind of a project and tasks to be solved, available specialists, etc. Here at ISS Art we know the best ways to transfer data without any loss.
Based on ISS Art company experience, we can say data migration is useful when we work with one type of data, and we need another type as an output (for example, a Customer needs to generate reports in another form). In case there is one database, and having another one is preferable, conversion tools can be used. Spark – an engine for data stream analysis – is one of them.
We rendered data migration services to our Customers while working on complex projects. When building a social network for music lovers, we implemented big data migration. In particular, we transported data from PostgreSQL to Hadoop, converted it to a proper format with Spark, and inserted back to PostgreSQL.
If your project deals with data of different types and structures, and your desired output is another format — don’t worry, we know what to do. ISS Art is happy to be your consultant and your service provider. Get in touch with us to learn more.
