TechRadar pro IT insights for business. Although the space it uses varies depending on the system where it's installed, it can take up less than KiB of space. User-friendly : SQLite is sometimes described as a "zero-configuration" database that's ready for use out of the box.
Popular Mac Software
SQLite doesn't run as a server process, which means that it never needs to be stopped, started, or restarted and doesn't come with any configuration files that need to be managed. These features help to streamline the path from installing SQLite to integrating it with an application. Portable : Unlike other database management systems, which typically store data as a large batch of separate files, an entire SQLite database is stored in a single file. This file can be located anywhere in a directory hierarchy, and can be shared via removable media or file transfer protocol.
Disadvantages of SQLite Limited concurrency : Although multiple processes can access and query an SQLite database at the same time, only one process can make changes to the database at any given time. No user management : Database systems often come with support for users , or managed connections with predefined access privileges to the database and tables. Because SQLite reads and writes directly to an ordinary disk file, the only applicable access permissions are the typical access permissions of the underlying operating system.
This makes SQLite a poor choice for applications that require multiple users with special access permissions. Security : A database engine that uses a server can, in some instances, provide better protection from bugs in the client application than a serverless database like SQLite. For example, stray pointers in a client cannot corrupt memory on the server. Also, because a server is a single persistent process, a client-server database cancontrol data access with more precision than a serverless database, allowing for more fine-grained locking and better concurrency.
Examples include single-user local applications and mobile applications or games. Disk access replacement : In cases where an application needs to read and write files to disk directly, it can be beneficial to use SQLite for the additional functionality and simplicity that comes with using SQL. Testing : For many applications it can be overkill to test their functionality with a DBMS that uses an additional server process. SQLite has an in-memory mode which can be used to run tests quickly without the overhead of actual database operations, making it an ideal choice for testing.
However, the SQLite website recommends that any database approaching 1TB be housed on a centralized client-server database, as an SQLite database of that size or larger would be difficult to manage. High write volumes : SQLite allows only one write operation to take place at any given time, which significantly limits its throughput. If your application requires lots of write operations or multiple concurrent writers, SQLite may not be adequate for your needs.
Network access is required : Because SQLite is a serverless database, it doesn't provide direct network access to its data. This access is built into the application, so if the data in SQLite is located on a separate machine from the application it will require a high bandwidth engine-to-disk link across the network. This is an expensive, inefficient solution, and in such cases a client-server DBMS may be a better choice.
Numeric types : Data Type Explanation tinyint A very small integer. The signed range for this numeric data type is to , while the unsigned range is 0 to The signed range for this numeric type is to , while the unsigned range is 0 to The display length of entries for this data type is defined when the column is created, and every entry adheres to that length. String types : Data Type Explanation char A fixed-length string; entries of this type are padded on the right with spaces to meet the specified length when stored.
Advantages of MySQL Popularity and ease of use : As one of the world's most popular database systems, there's no shortage of database administrators who have experience working with MySQL. Likewise, there's an abundance of documentation in print and online on how to install and manage a MySQL database, as well as a number of third-party tools — such as phpMyAdmin — that aim to simplify the process of getting started with the database. Security : MySQL comes installed with a script that helps you to improve the security of your database by setting the installation's password security level, defining a password for the root user, removing anonymous accounts, and removing test databases that are, by default, accessible to all users.
Replication : MySQL supports a number of different types of replication , which is the practice of sharing information across two or more hosts to help improve reliability, availability, and fault-tolerance. This is helpful for setting up a database backup solution or horizontally scaling one's database. Licensing and proprietary features : MySQL is dual-licensed software, with a free and open-source community edition licensed under GPLv2 and several paid commercial editions released under proprietary licenses.
Because of this, some features and plugins are only available for the propriety editions. Slowed development : Since the MySQL project was acquired by Sun Microsystems in , and later by Oracle Corporation in , there have been complaints from users that the development process for the DBMS has slowed down significantly, as the community no longer has the agency to quickly react to problems and implement changes. Websites and web applications : MySQL powers many websites and applications across the internet. This is, in large part, thanks to how easy it is to install and set up a MySQL database, as well as its overall speed and scalability in the long run.

Expected future growth : MySQL's replication support can help facilitate horizontal scaling. Additionally, it's a relatively straightforward process to upgrade to a commercial MySQL product, like MySQL Cluster, which supports automatic sharding, another horizontal scaling process. Concurrency and large data volumes : Although MySQL generally performs well with read-heavy operations, concurrent read-writes can be problematic.
Numeric types : Data Type Explanation bigint A signed 8 byte integer. Character types : Data Type Explanation character A character string with a specified fixed length. Date and time types : Data Type Explanation date A calendar date consisting of the day, month, and year. Geometric types : Data Type Explanation box A rectangular box on a plane. Bit string types : Data Type Explanation bit A fixed-length bit string. Text search types : Data Type Explanation tsquery A text search query.

Other data types : Data Type Explanation boolean A logical Boolean, representing either true or false. Open-source and community-driven : A fully open-source project, PostgreSQL's source code is developed by a large and devoted community. Similarly, the Postgres community maintains and contributes to numerous online resources that describe how to work with the DBMS, including the official documentation , the PostgreSQL wiki , and various online forums.
Extensible : Users can extend PostgreSQL programmatically and on the fly through its catalog-driven operation and its use of dynamic loading. One can designate an object code file, such as a shared library, and PostgreSQL will load it as necessary. Each new process is allocated about 10MB of memory, which can add up quickly for databases with lots of connections. One consequence of this is that there are still fewer third-party tools that can help to manage a PostgreSQL database.
Similarly, there aren't as many database administrators with experience managing a Postgres database compared to those with MySQL experience. Integration with other tools : PostgreSQL is compatible with a wide array of programming languages and platforms. This means that if you ever need to migrate your database to another operating system or integrate it with a specific tool, it will likely be easier with a PostgreSQL database than with another DBMS. Complex operations : Postgres supports query plans that can leverage multiple CPUs in order to answer queries with greater speed.
This, coupled with its strong support for multiple concurrent writers, makes it a great choice for complex operations like data warehousing and online transaction processing.

Simple setups : Because of its large feature set and strong adherence to standard SQL, Postgres can be overkill for simple database setups. For read-heavy operations where speed is required, MySQL is typically a more practical choice. Complex replication : Although PostgreSQL does provide strong support for replication, it's still a relatively new feature and some configurations — like a primary-primary architecture — are only possible with extensions.
Replication is a more mature feature on MySQL and many users see MySQL's replication to be easier to implement, particularly for those who lack the requisite database and system administration experience.
