![]() The sort of database you choose should depend on the type of application you will be using the database with. It’s flexible enough to be used as a cache or message broker and can use data structures like lists, sets, and hashes. Redis is known for its flexibility, performance, and wide language support. It uses key-value pairs for storage instead of documents. Redis is is an open-source NoSQL in-memory data structure store. It's good for flexibility and unstructured data, and caching real-time analytics. It is horizontally scalable, which means multiple smaller machines will do the work for you. MongoDB is an open-source NoSQL document database designed to work with JSON and store schema-free data. SQLite is an open-source self-contained, file-based, “serverless” database, known for its portability, reliability, and good performance even in low-memory environments. These are also relational database management systems set up on servers with primary function of storing and retrieving data as requested by software applications. Microsoft SQL Server includes SQL Server on Windows, SQL Server on Linux, and SQL on Azure. It can handle JSON now too, but it is generally better for structured data, vertical scaling, and ACID-compliant needs like eCommerce and financial transactions. PostgreSQL (sometimes referred to as Postgres) is also an open-source SQL relational database with an emphasis on extensibility and standards compliance. It is currently the most widely used of the four database systems. It is vertically scalable, which means one ultimate machine will do the work for you. MySQL is an open-source SQL relational database, organizing data into one or more tables in which data types may be related to each other. The most popular choices for a database system include: Linux distribution running in WSL 2 mode.Install WSL and create a user name and password for the Linux distribution.Running Windows 10, updated to version 2004, Build 19041 or later.Get started with MySQL, PostgreSQL, MongoDB, Redis, Microsoft SQL Server, or SQLite. To attach an encrypted database using a binary password: // Attach to a database encrypted with a binary keyĬmd = new SQLiteCommand("ATTACH DATABASE 'c:\\pwd.This step-by-step guide will help you get started connecting your project in WSL to a database. If you are attaching an encrypted database using a cleartext password: // Attach to a database using a different key than the main databaseĬmd = new SQLiteCommand("ATTACH DATABASE 'c:\\pwd.db3' AS KEY 'mypassword'", cnn) ![]() To change this behavior, you use the KEY modifier as follows: Opens an encrypted database by calling SetPassword()Ĭnn.SetPassword(new byte ) īy default, the ATTACH keyword will use the same encryption key as the main database when attaching another database file to an existing connection. Passwords specified in the ConnectionString must be cleartext, but passwords supplied in the SetPassword() function may be binary byte arrays. To open an existing encrypted database, or to create a new encrypted database, specify a password in the ConnectionString as shown in the previous example, or call the SetPassword() function before opening a new SQLiteConnection. ![]() Removes the encryption on an encrypted database. SQLiteConnection cnn = new SQLiteConnection("Data Source=c:\\test.db3 Password=mypassword") To decrypt an existing encrypted database call ChangePassword() with a NULL or "" password: // Opens an encrypted database The connection remains valid and usable afterwards. SQLiteConnection cnn = new SQLiteConnection("Data Source=c:\\test.db3") To encrypt an existing unencrypted database, or to change the password of an encrypted database, open the database and then use the ChangePassword() function of SQLiteConnection: // Opens an unencrypted database You can use the built-in encryption of the sqlite.
