A simple class to implement in-memory database complex structures, to provide:

• Ultra fast speed (every column or field is a simple array)

• Big-data ready, billions of cells supported

• Multi-platform (Windows, Mac OSX, Android, iOS, Linux and more), for VCL, Firemonkey, Delphi and C++. 100% Pure Pascal, no dependencies, no server, just RTL.

• Automatic visualizations of complex structures (charts, grids, optional TeeGrid and more)

• SQL-like high-speed queries and summaries by code or "select" scripts

• Multi-dimensional Excel-like pivot tables, with drag & drop editor

• Geographic database (Countries, States, Provinces...) to automatically create summary geo queries, TeeChart world maps, and statistics

• Transparent optional remote web server fast data access (compressed binary streams of raw arrays)

• Automatic relationships between columns (master-detail), indexes and foreign keys

• Import data from files, databases, objects (ORM), AI in one or few lines of code

• Export data (to csv,pdf,html,xml,excel,json), comparisons, manipulations and conversions

• TeeBI makes very easy to create custom dashboard no-code analytic applications for your end-users. Ready to use dialogs enable easy runtime connections to many database engines and to all kind of data sources, and drag and drop in the query dialogs allow selecting fields as measures, dimensions, parameters and filters with just mouse clicks.

• Supported development environments:

  • Embarcadero RAD Studio Florence 13.0, and from Studio XE4 and up (Delphi and C++)
  • Lazarus / FreePascal

• Installer Tool and Installing info

uses BI.DataItem, BI.CSV, BI.Db, BI.Xml, BI.Json, BI.AI;

var Data1 : TDataItem;
Data1 := TBICSV.FromFile( 'mydata.csv' );  // also From TStrings, String etc

// other importing methods:
Data1 := TBIDB.From( SQLConnection1 ); // loads all tables in one line of code
Data1 := TBIJson.From ...
Data1 := TBIXML.From ... // import different formats

// import from Artificial Intelligence AI agents, like Google Gemini:
Data1 := TBIAI.From('Give me the list of the highest 10 mountains by elevation in csv format, just the list');

// from arrays, TCollection, custom Records (via RTTI):
Data1 : TTypeProvider<TCustomer>.Create(Self, MyArrayOfCustomers).Data; 

// import from components with automatic detection:
Data1 := TComponentImporter.From(Self, Memo1.Lines);
Data1 := TComponentImporter.From(Self, DataSource1);

// importing from any URL, automatic detection of content format:
Data1 := TBIURLSource.From('https://www.mysite.com/get/mydata?param=123');

// queries, including group by, sort, expressions, having, sub-select, distinct, date operators etc
Data1 := TBISQL.From( Data2, 'sum(Amount) where (Customer=123) and (Product<456) group by Country, Year');
Data1 := TBISQL.From( Data2, 'ProductName, UnitPrice where UnitPrice > select Average(UnitPrice)');
Data1 := TBISQL.From( Movies, 'top 100 offset 15000 year, length');

// visualizing
BIGrid1.Data := Data1;
BIChart1.Data := Data1;

BIGrid2.Data := Data1['Products']; // sub-tables

// importing data from a standard TeeChart Series:
Data1 := TChartData.From(Series1);
