This makes tasks like in-database real time analytics feasible. PostgreSQL vs. MS SQL Server is one perspective on the differences between the two database servers from a data analyst. Designing Highly Scalable Database Architecturescovers horizontal and vertical scaling, replication and caching in relational database architectures. Five Mistakes Beginners Make When Working With Databasesexplains why you should not store images in databases as well as why to be cautious with how you normalize your schema.
Alternative storage abstractions are explained on the NoSQL page. Databases are a concept with many implementations, including PostgreSQL, MySQL and SQLite. Learn more in the data chapter or view the table of contents for all topics.

MySQL is another viable open source database implementation for Python applications. MySQL has a slightly easier initial learning curve than PostgreSQL but is not as feature rich. The database storage abstraction most commonly used in Python web development is sets of relational tables.
Object-relational mappers allow developers to access data from a backend by writing Python code instead of SQL queries. Each web application framework handles integrating ORMs differently. There’san entire page on object-relational mapping that you should read to get a handle on this subject.
Databases 101 gives a great overview of the main relational database concepts that is relevant to even non-developers as an introduction. is a detailed longform post on the sorting, searching, merging and other operations we often take for granted when using an established relational database such as PostgreSQL. SQL Tutorial teaches the SQL basics that can be used in all major relational database implementations.
Before complex data warehousing and before the cloud, there was the desktop database designed to run on a single machine. These solutions are simple and inexpensive, but also fairly limited in terms of data availability, storage, and functionality. A non-relational database is modeled by means other than the tabular system used in the relational database. A major advantage of the non-relational database is that it can easily incorporate and store all kinds of Big Data, including unstructured and semi-structured data.
You may plan to use anobject-relational mapper as your main way of interacting with a database, but you should still learn the basics of SQL to create schemas and understand the SQL code generated by the ORM. The following resources can help you get up to speed on SQL if you have never previously used it. BitCan provides both MySQL and MongoDB hosted databases with extensive backup services.
They also give you a mental framework for how the data should be saved and retrieved instead of having to figure out what to do with the data every time you build a new application.

- 80% of their typical actions such as starting a timer, attaching a file or updating status can be done straight from their dashboards.
- Collaboration is powerful with project discussions, @mention comments, file sharing, document version control, and activity stream.
Everyone agrees that data stores just keep getting larger, so scalability is also a factor that should affect your decision. When looking at database software, you should understand how growth can be managed and how the system can adapt to upgrades throughout your IT infrastructure.
