As the data in a database increases, search performance can suffer. The larger the dataset, the harder it is for the database engine to find the documents that match the query quickly. Database administrators can use indexes to aid the database engine and improve its performance. In this tutorial, you’ll learn what indexes are, how to create them, and confirm whether they’re used to query the database.
MySQL supports the use of stored procedures, which group one or multiple SQL statements for reuse under a common name. Using stored procedures, you can create reusable routines for common tasks to be used across multiple applications, provide data validation, or deliver an additional layer of data access security. In this tutorial, you’ll learn what stored procedures are and how to create basic stored procedures that return data and use both input and output parameters.
When retrieving data from a database, you may need to refer to more than one table at a time. In Structured Query Language (SQL), you can use the `UNION` operation, which takes the results of two queries with matching columns and merges them into one. In this guide, you will use `UNION` operations to retrieve data from more than one table simultaneously and combine the results. You will also combine the `UNION` operator with filtering to order the results.
Managed databases were developed to reduce the pain points commonly associated with database administration. This conceptual article outlines what managed databases are, how they can be beneficial to development teams, and some practical considerations one should make before building an application on top of one.
This conceptual article serves as an introduction to numerous database topics. It provides a brief overview of what databases are in the context of cloud computing and highlights a few concepts central to their design and function. It also contains links to relevant conceptual and procedural tutorials throughout.
