Creation Of Material Views.

Hi,
I would like to create views in TOAD 9.1 Application.
Could any one help me how to write Sql.

Below are the tables which i have created.
1) DIM_RANK_GRP:


CREATE TABLE DIM_RANK_GRP
(RANK_GRP_ID NUMBER NOT NULL,
RANK_GRP VARCHAR (20),
PARENT_RANK_GRP VARCHAR (20)
HIERARCHY_TYPE VARCHAR (20)
);

ALTER TABLE DIM_RANK_GRP
ADD PRIMARY KEY (RANK_GRP_ID)


2) DIM_PROFITABILITY:


CREATE TABLE DIM_PROFITABILITY
(
PROFIT_ID NUMBER NOT NULL,
PROFIT_VAL NUMBER,
PROFIT_DESC VARCHAR (30)
);

ALTER TABLE DIM_PROFITABILITY
ADD PRIMARY_KEY (PROFIT_ID)


3) Fact Table: Agg_Rx_Weekly_Sales:



CREATE TABLE AGG_RX_WKLY_SLS
(TERR_ID Number,PFZ_PROD_ID Number ,DT_SK Date,CHNL_ID Number,SPEC_ID Number,RANK_GRP_ID Number,PRFTY_ID Number,Nrx Float(64),Trx Float(64),
Nrx_unit Float(64),Trx_unit Float(64),Nrx_Dol Float(64),Trx_Dol Float(64),Mkt_Nrx_Unit Float(64),Mkt_Trx_Unit Float(64),Mkt_Nrx_Dol Float(64),Mkt_Trx_Dol Float(64),Mkt_Nrx Float(64),Mkt_Trx Float(64)
);


ALTER TABLE “AGG_RX_WKLY_SLS�
ADD CONSTRAINT FK_DIM_TERR
FOREIGN KEY (“TERR_ID�)
REFERENCES “DIM_TERR� (“TERR_ID�);

ALTER TABLE�AGG_RX_WKLY_SLS�
ADD CONSTRAINT FK_DIM_PERD
FOREIGN KEY (“DT_SK�)
REFERENCES “DIM_PERD� (“DT_SK�);

ALTER TABLE “AGG_RX_WKLY_SLS�
ADD CONSTRAINT FK_DIM_SPEC

ALTER TABLE “AGG_RX_WKLY_SLS�
ADD CONSTRAINT FK_REL_PROD_MKT
FOREIGN KEY (“PFZ_PROD_ID�)
REFERENCES “REL_PROD_MKT� (PFZ_PROD_ID�);

ALTER TABLE “AGG_RX_WKLY_SLS�
ADD CONSTRAINT FK_DIM_RANK_GRP
FOREIGN KEY (“RANK_GRP_ID�)
REFERENCES “DIM_RANK_GRP�(RANK_GRP_ID�);

ALTER TABLE “AGG_RX_WKLY_SLS�
ADD CONSTRAINT FK_DIM_PRFTY
