![]() MongoDB: Connecting from the Command Line Note, settings such as the database username and password, and allowed IP ranges for connection can be set in the Database Access and Network Access links, respectively.īelow are two connection examples. The strings below can also be retrieved by logging into MongoDB Atlas Site and clicking the Connect button:įigure 1 – the MongoDB Atlas Dashboard with the Connect Button Highlighted Upon successfully configuring the Cloud-Based MongoDB Cluster, it will be necessary to note the particular connection string used to connect to it. How to Connect to the MongoDB Database Server Always make sure to include the path to the folder which contains this application in the Operating System path. The MongoDB Shell may not have an installation program.Ensure that any IP address from which any application, including MongoDB Shell, is configured in the security settings.The demonstrations in this article will use a cluster named Cluster0. The Cluster Name, once set, cannot be changed.The password that is used to connect an application to the database server must be saved securely as it cannot be recovered if it is lost. ![]() The hosting service shown in this article which is in Virginia may not be ideal for someone who is far away from there. Choose a data hosting service that is physically nearby.It can conveniently be linked to one’s Google account for the purposes of single-sign-on. The MongoDB Zero-Cost Cloud-Based Introductory Offering configuration is entirely web-based. How to Configure MongoDB for Software Development If the links are no longer active, these products can be downloaded via one’s preferred search engine. Please note that the links posted were active at the time this article was written. MongoDB Zero-Cost Cloud-Based Introductory Offering.Note that MongoDB Shell is one of many management tools that exist for MongoDB. The demonstrations in this article will use a MongoDB database created using this tool. Furthermore, like any database server, MongoDB provides a companion management tool called MongoDB Shell. ![]() The demonstrations in this database programming tutorial will use the cloud-hosted free instance of MongoDB.Īs is the case with Python and any database server, an additional database driver module, namely PyMongo, is required for Python to communicate with the MongoDB server and any databases contained within it. MongoDB, in addition to offering zero-cost downloadable server software, also offers a zero-cost cloud-based introductory option (via its Atlas offering) which mitigates the need for downloading and configuring an instance. Like MariaDB, it uses its own username and password system for access management. MongoDB is one of many “NoSQL” databases. NoSQL database servers are more focused on speed and scalability with “eventual consistency”, as opposed to SQL database servers which are focused more on immediate consistency. ![]() Going further under the hood, the design of NoSQL database servers shares the same dissimilarity. A developer who is more used to the SQL programming paradigm must adapt his or her thinking to match how NoSQL does business. NoSQL databases, in addition to mostly not using a query language, also structure data internally in a manner that is significantly dissimilar to SQL databases. This greatly eases application development because the native data structures of the programming language and its syntax are the de facto “query language,” provided of course the appropriate modules are added to the development environment. One of the most appealing features of these types of databases is the fact that there is, as the name implies, generally no additional query language, such as one of seemingly many variants of SQL, that must be learned in order to work with the database from a programmatic standpoint. One such “new” technology is the use of “NoSQL” databases. Python’s popularity continues to grow in popularity in part because of the ease of which it can work with new technologies. The demonstrations in this article will parallel the demonstrations used in other SQL Database programming articles involving Python, such as Python Database Programming with SQL Express for Beginners, and likewise, will use Python 3. The intended audience is beginner-level developers or intermediate-level developers who are familiar with using SQL-oriented databases such as Oracle, SQL Server, or MySQL. The purpose of this Python database programming tutorial is to provide a gentle introduction to using a NoSQL database as a data store for Python applications.
