![]() ![]() ZODB is better suited for the following scenarios: No separate language is needed for operations related to the database.Seamless integration between code and database.ZODB is a native object database for Python. from tinydb.storages import MemoryStorage The default value is JSON, and if you want to change it to in-memory, you need to specify that explicitly. TinyDB enables developers to handle data in two different ways, as listed below: To delete all the values, give the following commands: db.purge() To remove values, type: db.remove(unt < 900) ![]() The following code snippet explores how to create and store the values in TinyDB: from tinydb import TinyDB, Queryĭb.insert(] As is the case with many other packages, TinyDB can be installed simply with the following command: $ pip install tinydb Having seen the pros and cons of TinyDB, let us look at how to use it. Similarly, HTTP server based access is another scenario in which it won’t be suitable. If you need to access the database from multiple processes or threads, then TinyDB won’t be optimal.TinyDB is not suitable for those scenarios in which high speed data retrieval is the key.It has certain limitations as listed below: Though TinyDB has various advantages, it is not a single-size-fits-all solution for problems. With the help of middleware, TinyDB behaviour can be extended to suit specific needs. Extensibility is another major feature of TinyDB.In addition, TinyDB supports all the recent versions of Python. Another likeable feature of TinyDB is the non-dependency.Primarily, TinyDB has been designed keeping ease of usage in mind. The API of TinyDB is very simple and clean.This type of storage is adopted in popular tools such as MongoDB. TinyDB is based on document-oriented storage.The complete source code is only 1200 lines. As the name indicates, TinyDB is very small.The major features of TinyDB are listed below: The applications which are best suited to TinyDB are small apps for which a traditional SQL-DB server based approach would be an overload. As the official documentation says, TinyDB is a database optimised for your happiness. It is written 100 per cent in Python and has no external dependencies. Figure 1: Python databases TinyDBĪs the name indicates, TinyDB is a compact, lightweight database and is document-oriented. PickleDB can be used for those scenarios in which the key-value store type of format is suitable. DUMP: Saves the database from the memory into the file specified with the load command.Īpart from the above mentioned commands there are various other commands.GETALL: Used to fetch all the keys in a database.GET key: Used to retrieve the value of the key.SET key value: This is the value of a key with the string.LOAD path dump: This is used to load a database from a file.Some of the popularly used commands of pickleDB are explained below. > db = pickledb.load('example.db', False) The following code segment illustrates the basics of using pickleDB. Though the later versions of pickleDB started using the SimpleJSON module, the name pickle was retained. The name pickleDB is inspired by a Python module named pickle, which pickleDB was using earlier. It may be installed effortlessly with the following command: $ pip install pickledb SimpleJSON is a pure Python implementation with no dependencies it functions as an encoder and decoder for Python versions 2.5+.ĭeveloped by Harrison Erd, pickleDB is available with the BSD three-clause licence. It is based on the Python module named SimpleJSON, which allows developers to handle JSON (JavaScript Object Notation) in a simple and faster manner.
