What is a federated search?
Federal search is access to asking multiple data files with a single query request. This is commonly used to access information about specific data or products. The federated query is relatively simple and provides quick access to multiple data files in a combined report format.
Federal search is one of the most basic methods of accessing data from multiple databases. This saves time because one search query can be automatically done in many data files. Most search engines perform a form of federal search over the Internet. These engines can evaluate multiple resources with a single requirement and make information available.
The popular Google® search engine is an example of a federated query that reads unstructured data on the Internet. This federal search engine provides quick results of different data files. Federated questions are used by special indexing techniques that allow sorting and return quickly.
Funnelback® is an example of a searchHo tools that uses a federated search. This tool can read structured and unstructured data contained in multiple databases. This search tool is similar to the standard indexing search engine that reads data based on specific search criteria and returns it in a single sorted view.
One of the primary disadvantages of federated search is the overload of information that is returned from this type of query. When a federated query is performed across several data sources, thousands of records can be returned. This causes too much data that makes it irrelevant.
Federated search system usually returns thousands of records to a single question. This requires a special business algorithm to return the most important data at the top of the list. There are several techniques that can be used for sorting relevant data. Are usually based on accuracy, use and korElaction of data with other relevant data within data.
Many commercial tools help companies create federated search features. These tools usually include special software connectors and interfaces that allow you to connect different data files. The integration of these federated search tools requires a professional understanding of databases and data access techniques.
