Horváth F., Polgár L. (2008): MÉTA SQL expert interface and access service. Acta Botanica Hungarica> 50(Suppl.): 35-45.
Researchers of the MÉTA program have a strong demand to perform flexible and effective queries for further analyses of the database. Structured query language was applied and a web-based application was developed to facilitate understanding of database structure and content in detail, to help develop, store and annotate of SQL query statements, to help reuse of them, to facilitate save and download resulted data sets to the authorised users through the internet. A brief description of the MÉTA SQL Expert Interface and Access Service is given here, and several commented query examples demonstrate the easy and effective usage of the service.
