![]() It’s flexible because it allows you to process, transform, and analyze data of any structure.īecause of this, MongoDB allows fast data flows and features across 150 operators and expressions. You can use this framework to club several operators and expressions. To view a list of the collections that belong to a database, use the command listCollections. Secondly, the documents needn’t be of the same data type! They’re similar to tables in relational databases.Ĭollections, however, are much more flexible. CollectionsĪ collection is a group of documents associated with one database. They also offer protection against downtime during a system failure or planned maintenance. These copies are known as “ replica sets,” and they continuously replicate data between them, ensuring improved availability of your data. When you create a new database in MongoDB, the system automatically creates at least 2 more copies of your data. This ensures faster access and increased support for various data types like string, integer, boolean number, and much more! Replica Sets Additionally, MongoDB converts documents into a binary JSON (BSON) type. Fields in a JSON document can differ from document to document, so they won’t be added to every record in the database.ĭocuments can store structures like arrays that can be nested to express hierarchical relationships. That’s not the case with fields in a JSON document. In a relational database table, you must add a column to add a new field. A good database server provides tools to measure and profile the workload and performance at different usage points to utilize the available resources effectively.Uncover performance bottlenecks to deliver a better user experience and hit your business’s revenue goals. Sometimes, one of these resources may be overused, and others may be underutilized. ![]() Resource utilizationĮfficient utilization of resources like CPU, disk, or memory is essential for proportionate usage. Performance is a challenge that needs to be constantly worked upon by techniques like scaling, indexing, query optimization, and following best practices. When you test your application with 1000 users, the performance you get might not be the same as for a million or more concurrent users. ![]() Modern databases provide horizontal as well as vertical scaling capabilities. Scaling is complex, especially because the number of users can keep going up. The database system should be able to handle the increase in data. Your application data will increase as your user base increases. A good database should follow security best practices and provide end-to-end data protection. Hackers are always on the move and security measures need to be upgraded every now and then. However, thanks to modern databases, these challenges can be easily overcome. A DBMS achieves data independence at different levels: view, physical, and logical.Ĭommon database challenges and how to overcome themĪlthough data integrity and security are key benefits of a good database system, these are also challenges that need constant attention because of the high volume and availability of data over the internet. For example, end-users and applications need not know the internal data storage structure and are not affected by internal schema changes. ![]() ![]() Schema changes at one level do not impact the data at another level. Data independenceĭata independence helps in abstracting data representation details from application programs. Backup and recoveryĭBMSs can be configured to take care of periodic backup and recovery in case of a failure. Data securityĭatabase systems ensure data security and privacy by providing authentication and access control measures. Faster accessīy using database hosting, query optimization, indexing, and other performance optimization techniques, database systems ensure that users can retrieve and store data efficiently. Data integrityĪt any point in time, database systems ensure maximum consistency by providing provisions for regular archiving, backups, data audits, input validations, removing redundancies, and so on. The most important advantages of DBMS are security, faster data access, data independence, and data integrity. ![]()
