TeeBI

Datamining, Visualization, Machine-Learning, Big data

What is TeeBI ?

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

Ultra fast speed (every column or field is a simple array)
Import data from files, databases, objects (ORM) in one or few lines of code
Automatic relationships between columns (master-detail), indexes and foreign keys
SQL-like high-speed queries and summaries by code or "select" scripts
Geographic database (Countries, States, Provinces...) to automatically create summary queries and TeeChart world maps
Transparent remote web server fast data access (compressed binary streams)
Automatic visualizations of complex structures (charts, grids and more)
Interactive Dashboards rendered to screen (desktop and mobile) and HTML Web pages
Data export (csv,pdf,html,xml,excel,json), comparisons and manipulations
Machine-learning and statistics (native data pass to R Language and Python Scikit)
Big-data ready, billions of cells supported
Multi-platform (Windows, Mac OSX, Android, iOS, Linux and more)
Supported development environments:
- Embarcadero RAD Studio 11.3 Alexandria, and from Studio XE4 and up (Delphi and C++)
- Lazarus / FreePascal

steema-bi-samples's Issues

Multi-column master-detail links not working in BIDataset

Note: Single column/field works fine

Delay-loaded TDataset import

A boolean parameter in TBIDB Import method to not load all Dataset records, but just create and return a TDataItem filled with the structure of the Dataset (fields and subfields).

In this delayed mode, records will be loaded just-in-time when they are necessary (for example when calculating a query or presenting the TDataItem on a grid or chart).

This mechanism is already working when loading TDataItem from a binary file or stream (mydata.databi) so it should be easy to implement for both TDataSet and TConnection sources. The only issue here is the source dataset might be closed or destroyed before data has been loaded, in that case the TDataItem should not attempt to load data and just keep itself empty.

Refreshing the data items is also very easy, just call MyData.UnloadData and the internal delay-load flag will be reset, the data item will be emptied, and it'll load a new refreshed copy of the database data the next time is necessary

TObjectExpression support for complex expressions

TObjectExpression currently supports Object + field or property ( Edit1, 'Text' )

The enhancement is to support free expressions like:

'Button1.Width * 42 + (Panel1.Position.X / 3)'

A possible syntax:
var E : TExpression;
E:= TObjectExpression.From(Self, ' ......the expression...');
Caption:= E.Value;

The "Self" parameter is the "root" starting object, collection or component where to look for references in the expression (in this example, the Form owner of Button1 and Panel1)
