Imagine you’re working in a UNIX-based environment, managing multiple databases like MariaDB, PostgreSQL, or Oracle, and you have to connect their data to different applications. Without UNIX ODBC drivers, you’d have to write custom code for each database, which would quickly turn into a nightmare — each database has its own way of handling queries, connections, and authentication. Luckily, ODBC drivers can save the day by acting as “translators”.

Components in Delphi save the essential time it often takes for developers to write code from scratch, providing pre-built options you can continuously reuse to assemble software, create a smooth user interface, and handle complex data connectivity tasks. Streamlined development, reduced number of errors, and consistency are only some of the advantages that you get when using components while you work with Delphi.

A data type is a particular kind of data item that is defined by the values it can take and the operations that can be performed on it. SQL supports various data types, including numeric, date and time, character and string, binary, and more. The choice of data type affects data integrity, storage, and performance; the choice of the optimal data type is not always all that obvious.

Oracle Database remains a global leader in database management, valued for its power and enterprise-level features. It is often the default choice for managing large databases and handling complex transactions, despite its complexity and cost. Effective tools for working with Oracle Database can significantly ease the workload for specialists. Both Oracle Corporation and various third-party vendors have developed a range of solutions designed for diverse database-related tasks in Oracle environments.

In one of our previous articles, we discussed how to rename a database in MySQL in detail. In this article, we will focus specifically on renaming tables in MySQL. Rename table operations are common. Quite often, as business situations and requirements change, it becomes necessary to change the names of tables in MySQL databases.

Here comes an update of Devart ODBC Drivers, our high-performance connectivity solutions that enable access to a variety of data sources from ODBC-compliant reporting, analytics, BI, and ETL tools on both 32-bit and 64-bit Windows, macOS, and Linux. Our Drivers fully support standard ODBC API functions and data types, grant easy and secure access to live data from 80+ sources, and can be integrated with 100+ third-party tools.

Restoring a database backup directly from a newer version of SQL Server to an older one fails or causes incompatibility errors. For example, a backup created on SQL Server 2019 cannot typically be restored on a SQL Server 2017 instance. Since a direct downgrade isn’t possible, we’ll demonstrate alternative methods to migrate a SQL Server database from 2019 to 2017.

An integrated development environment (IDE) for Delphi can streamline workflows, making it easier to deliver high-quality applications. The best Delphi IDE is essentially an all-in-one toolkit for crafting, testing, and deploying your application. Advanced IDEs empower developers to modernize data access components while preserving code security. Yet, not all of them ease the complexities of multi-platform development in the same way.

The importance of regular database backup and recovery can be neither underestimated nor ignored. And since your data is subject to modification, the primary task is to ensure its safety and mitigate the risks of data loss. That’s why we have database backups at hand—and in this article, we’ll guide you through main types and key concepts of backups as related to SQL Server databases.

When it comes to building interactive, scalable, and data-driven websites and applications, you may consider a combination of PHP with MySQL. Integrating PHP as a server-side language with MySQL as a relational database allows for dynamic content generation, user authentication, form handling, and easier data management. In the article, we’ll explore several methods to connect PHP with a MySQL database, including the mysqli and PDO (PHP Data Objects) extensions.
