The mapper for Tag doesn t need to have the relation to Page specified because SQLAlchemy can already work it out via the secondary argument In this example, the Comment and Tag mappers actually need to be specified before the mapper for Page because the classes are used in the properties of the Page mapper You sometimes have to think quite carefully about the order mappers are defined in order to be able to specify all the relationships correctly in Python code One point to note is that this setup doesn t provide a way to get a list of pages that share one tag because you haven t specified a backref on the tags property in the Page mapper, but you can always use a query if you need that information.

The RAM in PDAs and cell phones, however, is typically not tamper-resistant. If an attacker gets ahold of a cell phone, it is much easier for the attacker to open up the device and access the chip containing the memory for the device. Another disadvantage is that a cell phone or PDA is usually larger than most smart cards. Finally, PDAs and phones are just little computers that can serve as a second factor, but can have bugs and software security vulnerabilities of their own. In addition, communication between such devices and other computers may be awkward but simple using wires. Wireless protocols such as Bluetooth can be used, but secure setup and association can be cumbersome.

When designing your mappers, there is a tradeoff between adding relational structure to express an important structure or to simplify accessing data that is frequently used vs the simplicity of using queries for things that might only occasionally be used Once again, SQLAlchemy has many more features than can be described here including lazy and eager loading, mapping to joins, and more The SQLAlchemy documentation is very good and has all the details..

When you are thinking about naming table columns, it is a strongly recommended that you don t start any of the column names with _. SQLAlchemy adds certain objects to mapped class instances, and each of these starts with _, so you won t want to create names that conflict with SQLAlchemy objects.

Another device that one could consider using for storing secrets is a key disk. A USB or key disk is a device that can attach into the USB port on a PC. A key disk has a set of non-volatile memory that can be used to store the bits of a secret or key. The key disk s biggest advantage is that it serves as a second factor. The key itself will not be on the user s PC, and will require the user to plug in the second factor, the USB key disk. However, most of these disks don t have a CPU that can run arbitrary programs. The device is not tamper-resistant. If an attacker gets ahold of it, he could simply stick the key disk into his PC and start reading the bits on it. In this case, a user could encrypt the bits on the key disk such that a password could be used to decrypt the data. As with smart cards, key disks have the problem of the untrusted reader. Whatever the user is entering the password into can be used to decrypt the bits on the key disk. The password could be potentially captured, and the key disk may not have good support for authentication.

Sometimes you can t rely on using a text file for your data For instance, you might want to support an already existing file format that is not text-based or you might want to produce smaller files By storing the actual data in a machine-readable, binary format instead of converting it to human-readable text, you can save both file size and complexity in your save and load method When you need to read and write binary data, you can use the QDataStream class There are two important matters you need to keep in mind when using data streams, however: data types and versioning With data types, you must ensure that you use exactly the same data type for the >> operator as for the << operator.
