Database Programming

Database creation
We can't see databases physically, but we create them

A database is a collection of data organized for quick search and access, which, together with a system for administration, organization, and storage of that data, constitutes a database system. These databases can be of different types, including relational, object-relational, hierarchical, and network databases, each with its unique features and advantages. (More about databases on Wikipedia)

Database Creation

When working with a large number of different data, a database is necessary. The database is physically created on a hard disk. In the case of Microsoft SQL Server, the database typically has two files. One file contains the structure and data, while the other contains temporary records. It is important to store the file with the structure and data on multiple disks that act as one, with the ability to recover in case of failure. In this context, speed is not the most important - data preservation is key. The file with temporary records (log) is not as important, so it is crucial that it writes quickly to the disk(s).

Automatic Database Backup

To preserve data in case of system failure or hacker attack, backups of the database are made. This process is automatically performed at certain intervals. If you are using Microsoft SQL Server and if the database is in full recovery mode, it is necessary to also back up the log file. It is best to store backups on a separate hard disk or network location.

Maintaining and Updating the Database

Besides these aspects, it is important to understand that databases require regular maintenance and updating. This includes query optimization, creating indexes for faster searches, and implementing security measures to protect data.

Types of Databases

There are different branded types of databases, such as MySQL, MariaDB, Microsoft SQL Server, PostgreSQL, Oracle, SQLite, MongoDB, and IBM Db2. Here are the databases I work with:

MySQL is a popular open-source relational database, known for its speed, reliability, and ease of use. MySQL is often used in web applications and supports a large number of users and operations. More information can be found on the MySQL official website.

MariaDB is a fork of the MySQL database, offering improved performance, additional functionalities, and is open to all users. MariaDB focuses on the community and offers advanced data management capabilities. More information can be found on the MariaDB official website.

Microsoft SQL Server is a relational database developed by Microsoft, known for its high level of integration with Microsoft products and data analysis tools. SQL Server offers scalability and security for business applications. More information can be found on the Microsoft SQL Server official website.

PostgreSQL is a powerful, open-source object-relational database, known for its advanced support for SQL standards and extensibility. PostgreSQL is ideal for complex applications and data analysis. More information can be found on the PostgreSQL official website.

Database Programming Costs

The cost of database programming can vary significantly depending on numerous factors. This includes the complexity of the database, the amount of data processed, as well as specific security and performance requirements. To get the most accurate cost estimate, it is best to contact me with details about your project. You can send me a message with a description of what you need, the size of the project, the time frame, and other relevant information, and I will provide you with a personalized cost and time estimate for database creation.
