Tiedonintegraatio

Tiedonintegraatio, also known as data integration, is the process of combining data residing in different sources and providing users with a unified view of it. This unification aims to make data more accessible and usable for a variety of purposes, such as analysis, reporting, and application development. It is a crucial concept in information technology and business intelligence, enabling organizations to leverage their diverse data assets effectively.

The need for tiedonintegraatio arises because data often exists in disparate systems, formats, and locations. These can include databases, spreadsheets, cloud applications, and legacy systems. Without integration, accessing and correlating information across these sources can be a complex and time-consuming task. Tiedonintegraatio employs various methods and technologies to address this challenge. These can range from simple data transfer and transformation techniques to more sophisticated approaches like data warehousing and master data management.

Key objectives of tiedonintegraatio include improving data quality, ensuring data consistency, and enhancing data accessibility. By consolidating data, organizations can gain a more comprehensive understanding of their operations, customers, and markets. This leads to better decision-making, improved operational efficiency, and the ability to identify new business opportunities. The process typically involves several stages, including data extraction, transformation, and loading (ETL), or extract, load, and transform (ELT). The choice of approach depends on factors such as the volume and complexity of the data, as well as the specific requirements of the organization.
