A Multi-Model Database Perfect for Building Microservices
Databases are commonly classified by the data model they conform to. Hierarchical databases structure their data elements in trees, relational databases store data in the rows and columns of interconnected tables, and document databases work with collections of objects stored in JSON (or other) document form.
Different database models excel at different tasks. For example, storing and managing large numbers of data points collected over time is trivial for a time series database, but unrealistically complicated and slow using a relational database.
Considering the abundance of database models in existence, how do we get the most from our data without using an overwhelming number of services? Take, for instance, a company that wants a document store for its orders, ACID reliability for its accounting, distributed counters for web analytics, and would also like to use incremental time series to track transaction volume.
Deploying and integrating multiple data stores to provide this set of services is likely to become a costly and complex balancing act.
An ideal solution would be deploying not several stores, but a single multi-model system that provides all the services you need. A multi-model database is exactly that, providing a set of services that in the past could be provided only by multiple specialized databases.
Why Choose a Multi Model Database
There are many advantages to using a multi-model database, which provides a single endpoint for your document store, time series, distributed counters, and other database services.
Cost-Efficiency
- Ongoing maintenance and the introduction of new versions and features are also less costly and much easier to implement for a single database.
High ROI
- The reduction in immediate expenses is followed by reduced operational expenditure, giving you another push toward ever-growing ROI.
Lower Learning Curve
- The learning curve of developers building services is focused and minimized, saving them and their employers much effort and time.
Increased Agility
- The enormous reduction in overall complexity is expressed in increased agility.
Excellent Support
- The same trustworthy contacts are available to support all services.
Counters
A RavenDB counter is a Conflict-free Replicated Data Type (CRDT). Multiple clients can modify the same counter concurrently with no conflict or data loss. Counters are kept outside the documents that own them, so updating a counter’s value doesn’t modify the document the counter belongs to. This way counter operations do not trigger document replication and remain cheap regardless of how many counters you have and how often their values are updated.
Revisions
By enabling the revisions feature, your system administrator can make RavenDB log changes made to your documents. This gives you a built-in audit trail ready for use when needed, and the ability to reconstruct documents to their previous versions. You can also use revisions to follow changes made in the database using subscriptions. This can be very useful for regression analysis, applying business rules and seeing how the data changes over time.
A Multi Model Database that Gives You ROI that Compounds Year after Year
A multi-model database, RavenDB, lets you become an information octopus, while only having to learn and maintain one system. But your gain over time goes well beyond the initial investment in a single system rather than in many, as this layout continues to encourage developer productivity and prevent unnecessary expenses year after year throughout the life of your project.
With RavenDB, your team can innovate faster, scale easier, and reduce the friction caused by juggling different platforms. Each component works seamlessly within the same ecosystem and enables efficient development workflows.
This cohesion minimizes context switching and eliminates the integration overhead. The result is a robust and secure foundation for demanding applications. In other words, your early investment in RavenDB pays off repeatedly, multiplying the value you gain as your application evolves.
