Frequently Asked Questions on Database Caching Strategy
What is database caching?
Database caching is a mechanism that stores frequently accessed data in temporary memory. Whenever the application requests the data again, that can quickly get it from this helper, instead of from the main database. Cache helps to reduce the database workloads.
Which is the most commonly used caching mechanism?
The Cache-Aside strategy is the most commonly used caching mechanism. Generally, it is used in e-commerce and other web applications. It is also called Lazy Loading.
Which caching strategy is suitable for applications with frequent read operations?
A Read-Through caching strategy is suitable for applications with frequent read operations. Read-Through caching involves fetching data from the main DB through the cache.
Which caching strategy ensure the data consistency between the cache and DB?
A Write-Through caching strategy ensures data consistency between the cache and DB. So it is used in the banking application which contains reliable information.
Which caching strategy is suitable for blogging applications?
The Write-Back caching strategy is suitable for blogging applications. The application first writes the content changes to the cache. Then the cache does write operation to the database with delay.
Which caching strategy may lead to data loss?
The Write-Back caching strategy may lead to data loss. Because the application directly writes the data to the cache at first, then the cache writes to the DB after some delay. There is a possible risk of data loss if the cache fails before writing to the database.
What is Caching Strategies in DBMS?
In today’s digital world, the speed of an application plays a major role in its success. Generally, users expect the applications to run faster with quick responses. Also, It should support seamless experiences across all their digital interactions, whether they’re browsing a website, mobile app, or a software platform. Caching is used to implement a high-speed system with a large number of users. A cache is a high-speed data storage that stores data temporarily to serve future requests faster.
Database caching is like a helper for your primary database (DB). It is a mechanism that stores frequently accessed data in temporary memory. Whenever the application requests the data again, that can quickly get it from this helper, instead of from the main database. Cache helps to reduce the database workloads. So it increases system speed by reducing the need to fetch data from DB.
