Just migrated from VB6 to Lazarus and Firebird

[asdf]

I'm so new to Lazarus.
After seeing some video tutorials,
I saw the tutor used 4 controls
such as TIBConnection, TSQLTransaction,TSQLQuery and TDatasource.
And the last one is TDBGrid to disply data.

Before that in VB6
I always used

sql1 = "select * From product Order By productcode"
Dim cndb As New ADODB.Connection
Dim rsdb As New ADODB.Recordset
cndb.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=inventory1.mdb;Persist Security Info=False"
cndb.Open
rsdb.Open sql1, cndb, adOpenStatic, adLockPessimistic
Text1.text=rsdb.Fields(0)
etc....

Could you please help teach writing code in Lazarus to connect firebird
the same style as I did in VB6. Thank you in advance.
