Data conversion refers to the process of changing data from one format to another, which is a crucial step in data integration. This allows data to be used in different applications or databases. Think of it like translating a text from one language to another so that people who speak different languages can read and understand it. In the same way, data conversion enables different networks or users to use the same data in different character sets or formats.
Why Data Conversion is Important
Hardware, operating systems, and computer programs all handle data differently, which means that data format varies, too. As a result, when data is transferred from one system to another, it needs to be converted into a compatible format that can be used by the receiving system. Data conversion allows this to happen, ensuring that data can be read and executed across different applications, databases, and operating systems.
How Data Conversion Works
Data conversion is usually performed using software tools that read data in one format, and convert it to another format. This process can be simple or complex, depending on the environment and data format. The converted data needs to preserve all its information, while enabling it to be used in the target application, database or system.
Data conversions are commonly performed when data is extracted from source systems and loaded into a data warehouse. The conversion can either be implemented as an ETL (Extract, Transform, Load) transformation or through the source-to-target mapping application.
What is the purpose of data conversion?
The primary purpose of data conversion is to enable interoperability between different systems and allow data to be read and used across different applications, databases and operating systems.
What are some common data conversion methods?
Some common data conversion methods include file conversion (CSV, XML, TXT), database conversion (from one database platform to another), and document conversion (PDF to Word or Excel).
Who usually performs data conversion?
Data conversion is usually performed by technical professionals such as software developers, data analysts, and database administrators using software tools that are designed for this purpose.
