From Text-based Genome, Population Variations, and Transcriptome Datafiles to SQLite Database and Web Application: A Bioinformatical Study on Alfalfa

In this study, a web database application with the Flask framework was developed to implement three types of queries and visualize the results over a bioinformatical dataset from Alfalfa ( Medicago sativa ). A backend SQLite database was constructed from genome FASTA, population variations, transcriptome, and annotation files with extensions “.fasta”, “.gff”, “vcf”, “.annotate”, etc. Further, a supplementary command-line-based Java application was also developed for faster access to the database without direct SQL programming. Overall, Python, Java, and HTML were the main programming languages used in this application. Those scripts and the development procedures are valuable for bioinformaticians to build online databases from similar raw datasets of other species. ### Competing Interest Statement The authors have declared no competing interest.
