Trino is an open-source distributed SQL query engine designed to query large data sets distributed over one or more heterogeneous data sources. [1] Trino can query data lakes that contain a variety of file formats such as simple row-oriented CSV and JSON data files to more performant open column-oriented data file formats like ORC or Parquet [2] [3] residing on different storage systems like ...
Comma-separated values (CSV) is a text file format that uses commas to separate values, and newlines to separate records. A CSV file stores tabular data (numbers and text) in plain text, where each line of the file typically represents one data record. Each record consists of the same number of fields, and these are separated by commas in the ...
The application can also import data (tables) from external data sources (MySQL, PostgreSQL, Microsoft Access files, dBASE files) and export data to MySQL or PostgreSQL servers. There is rich support for importing and exporting CSV files. The same CSV format can be used for copying and pasting clipboard data so the data can be easily ...
Hyper Text Structured Query Language (HTSQL) is a schema-driven URI-to-SQL query language that takes a request over HTTP, converts it to a SQL query, executes the query against a database, and returns the results in a format best suited for the user agent (CSV, HTML, etc.) [1] The HTSQL language is implemented on "HTSQL servers," which use HTSQL to convert web requests into equivalent SQL ...
Import data from CSV, JSON and SQL; Export data to various formats: CSV, SQL, XML, JSON, PDF (via the TCPDF library), ISO/IEC 26300 - OpenDocument Text and Spreadsheet, Word, Excel, LaTeX, SQL, and others; Administering multiple servers; Creating PDF graphics of the database layout; Creating complex queries using query-by-example (QBE)
The default install includes a web interface allowing end-users to execute ANSI SQL directly and export data tables as CSV files without any programming. The dashboard library, Apache Superset , [ 10 ] is particularly well suited for visualization of data queried with Drill.
It allows the use of SQL or another scripting language suitable for the data source to perform required transformations. Scriptella does not offer any graphical user interface . Typical use
