Section 8: Deploying Flask Apps to HerokuĪ free cluster is a single database that we can access, but there are also paid clusters that can make and manage multiple copies of the database.Retrieving Microblog entries from MongoDB.Formatting dates correctly in our entries.Displaying past entries in the Microblog project.Setting up the Microblog project with Flask.Using render_template to Send Longer HTML Strings.Section 7: Introduction to Flask and MongoDB.Section 6: Project 1: Micro Blog (design+site).Create a new Class under Services/CustomerService. Let’s start building a service that can perform CRUD operations over the Customer Collection. Here is a small sample of the how the object get’s saved in MongoDB. Here the data of the user as well as the address data will be stored in a single JSON object, which ultimately makes it much simpler and quicker to retreive the data. As mentioned earlier, Document databases work with JSON objects. Let’s see how a Document based NOSQL Db can handle it. Right? Although this can be easily queried with a single INNER JOIN, what happens when the complexity increases or the number of users grow drastically? It would not be recommended to make several Joins. The Address table will include fields like AddressId, UserId, Country, PhoneNumber where UserId is a foreign key relationship to the User table. Users table will include fields like UserId, FirstName, LastName, DateofBirth. Make 2 tables, namely dbo.Users and dbo.Adresses. Here is the ideal way to design it on a SQL Database. The user will have fields like FirstName, LastName, Date Of Birth, multiple addresses etc. The requirement is to design a datastore to store the data of User. To get a better understanding, let’s take a very simple example. Caching is a perfect use case of such databases. This is an excellent choice when you want to store tons of data that are very simple like user preferences, application language texts, country informations. Dictionary Databases – Redis is a great example of Key-Value Database.Graph Database – A more complicated form of NOSQL DBs which stores data in nodes and edges.We will be talking extensively on MongoDB in this article. ![]() It can be used to store a large amount of complex data which can in turn be easily queried without any compromise to the performance / response times. MongoDB is the most popular Document Database out there. Document Database – These databases allows you to store data in the form of JSON objects.Now, there a quite a lot of types of NOSQL Databases. The advantages with using NOSQL Databases are as follows. An example of such an use case is, You could NOSQL Databases as a secondary Database that can be used to Search purposes as we know that it can outperform SQL DB. You could have both SQL and NOSQL Databases under a single application. Note that, this doesnt mean SQL Databases is no longer recommended. ![]()
