3. Query.jl

For SQL-like data manipulation, Query.jl offers a powerful syntax that makes querying data intuitive. It's compatible with various data structures, allowing for complex transformations and analyses with ease.

Query is a package for querying julia data sources. It can filter, project, join and group data from any iterable data source, including all the sources supported in IterableTables.jl. One can for example query any of the following data sources: any array, DataFramesDataStreams (including CSVFeatherSQLiteODBC), DataTablesIndexedTablesTimeSeriesTemporalTypedTables and DifferentialEquations (any DESolution).

Query is heavily inspired by LINQ, in fact right now the package is largely an implementation of the LINQ part of the C# specification. Future versions of Query will most likely add features that are not found in the original LINQ design.

Features:

  • SQL-like syntax for data queries
  • Works seamlessly with DataFrames.jl and other data structures
