FireDAC Components

あらゆるデータソースにRDB と同感覚で連携が可能に



標準FireDAC Components


MySQL やSQL Server のようなRDBMS への接続と同感覚。 TDFManager、TDFConnection、TDFQueryUse といった標準FireDAC components として。


	FDConnection1.Name := 'Neo4JConnection';
	FDConnection1.DriverName := 'CData.Fire.Neo4J';
	with FDConnection1.Params as
	    TFDPhysCDataNeo4JConnectionDefParams do begin

	    ...
	end;


	FDConnection1.Connected := true;
	FDQuery1.Active := true;
	FDQuery1.Open('select * from Neo4J');

	...

Type SQL, Get Neo4J


データ連携アプリケーションを開発する最適解。 RDBMS の扱いと同感覚で、Neo4J への連携を、標準SQL で実装可能。JOIN、更新系、集計など多彩なSQL サポート。

SELECT WITH INNER JOIN

	SELECT Neo4J.Id, Neo4J.Name, Neo4J.Fax,
	  Opportunity.AccountId, Opportunity.CloseDate
	FROM Neo4J
	INNER JOIN Opportunity
	  ON Neo4J.Id = Opportunity.AccountId

集計関数

	SELECT Name, AVG(AnnualRevenue) FROM Neo4J GROUP BY Name

CRUD 処理

	UPDATE Neo4J SET Name='John' WHERE Id = @myId
