Biological data is scattered across many sources. This paper reviews methods for integrating diverse bioinformatics data, addressing challenges and evaluating tools for better data accessibility.

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Genomics

Background:

  • Biological data is increasingly dispersed across numerous sources like GenBank, EMBL, and SWISS-PROT.
  • These data sources include traditional databases and structured files in various formats (e.g., ASN.1, ACE).
  • Sequence analysis software (e.g., BLAST, FASTA) also generates data, acting as additional sources.

Purpose of the Study:

  • To survey the technical challenges in integrating heterogeneous biological data sources.
  • To classify existing approaches for data integration in bioinformatics.
  • To critique the available tools and methodologies for biological data integration.

Main Methods:

  • Literature review and survey of bioinformatics data integration strategies.
