5/17/2021 0 Comments Data IntegrationData integration refers to the process of integrating data from various sources and presenting them to users in a consistent manner. This procedure becomes important in various fields, which include scientific and business domains. This helps in developing a common view or picture of the data, by creating a relationship among various pieces of the data. While some data integration happens automatically, most of the work is manual and requires adequate attention, knowledge and skills. Integration of legacy systems can be a challenging task for users. This is because most legacy systems are designed to provide information that cannot be processed directly. They contain rich information and records, that need to be converted into a format that can be processed efficiently. Traditionally, legacy systems were created to provide access to information from legacy databases, rather than to provide a means of integrating new information into an organization. However, there are several ways of making a data integration solution, depending on the quality and size of the required data integration system. ETL (Extract, Transform, Load) is a common data integration technique used to extract data from large ETL collections. ETL tools convert large ETL collections into data sets that can be consumed directly by applications. ETL tools are available for MS Visual Basic, Java and Visual C++. The major component involved in ETL is an Extract-Transform-Load (ETL). The ETL tool transform data sets in such a way that they can be accessed directly by the application. Data transformations to Google Big Query generally extract the required data from sources in a format that can be processed directly by the software. Data transformations include source systems (e.g., Excel, Lotus Domino, SQL Server) and transformation procedures (e.g., grouping and subtotaling, merging, grouping by dimensions, and so on). ETL tool vendors offer different types of ETL tools, including web-based tools, packaged as a set of Windows or Linux software, and stand-alone tools. The ETL tool can be run with the software itself or as part of an integration or data warehouse management package. Web based ETL tools are generally less expensive than other ETL tool vendors. Data integration involves the establishment of one unified data integration platform that includes all source systems and application components. The unified data integration platform facilitates the integration of diverse data sources into a common store or platform. Common examples of data integration platforms are ERP systems and legacy architectures. Data integration involves the automation of data extraction, transformation, and analysis tasks. ETL, data integration, and integration concept are interrelated. They help in the automation of business process and improve overall organization productivity. Data integration is achieved by combining data from different sources using advanced analytical technologies. ETL methodologies enable collaboration among multiple organizations through an integrated communication platform. They provide a single unified view of enterprise information for better decision making.
