If a market accept Master card does it necessary means it accepts Maestro Card?

No but it is technically the same company. Maestro is the international debit card network. It will work at all place that take Maestro not MasterCard. I have done research on this subject. Yes you can use your card on the Internet but your bank must support this. Only a few countries allow this. Unfortunately the US does not allow this yet but Maestro cards can be used at some merchants in person with a pin by choosing the debit button. If you are in the US. You can get a debit card with a MasterCard symbol and use it on the web and it can be used at places in person that take either Maestro and/or MasterCard. Just a tip because of the way some merchants do their transactions on the Internet and off. I would keep at least double the purchase plus $5.00 in your account. Some hotels, restaurants and car rental put bigger holds on your card. I would use a credit card in this case. If you get an US debit card with either a Visa or MasterCard symbol on it. It could have any of these networks listed on the back of your card Star, Nyce, Visa Electron, Visa Delta, Visa Plus, Cirrus, Maestro, and your local bank network. Maestro and Visa Plus international network are used as the last resort when doing a debit (pin) purchase in the US and abroad and for compatibility with foreign issued cards.
