![]() In order to produce more sophisticated insights, analytical workloads may require complex queries involving multiple steps of joining, filtering and other data processing steps. For example, an analyst might be interested in calculating the average value of all orders placed last quarter in California. These database operations are called aggregate functions and involve grouping together and performing computations on values from many rows. Analytical workloadsĪs we mentioned above, analysts and data scientists are interested in processing large amounts of information in order to calculate summary statistics. ![]() While processing large amounts of data at once is great for data scientists, it’s not so useful for software engineers who are more concerned with manipulating objects on an individual level. Transactional workloads tend to focus more on individual objects and records than aggregate data. Though that’s still a very broad definition, that’s also the point - transactional databases can satisfy a very broad range of applications and workloads.īut before we get into that, let’s explore who uses them in the first place. While inconsistencies might occur while a transaction is in progress, they’re valid as long as the database regains its original consistency after a successful transaction.Īs you can probably imagine by now, a transactional database is simply one that supports this dynamic. In short, ACID guarantees that every transaction will keep the database consistent.
