![]() If you omit a filename, no data will be stored on the disk after exiting the DBMS. Whenever you use a file with the same name (and path), the data saved on the database's tables will be persisted (saved for later use). The parameter sqlite.db is the chosen name for the file that stores the database's data. Linux's distributions commonly offer different DMBSs (such as SQLite, PostgreSQL, MariaDB and MySQL). You should use root or administrator accounts only to install the DBMS.Īfter the installation, use a regular user account, with lower privileges, to run the DBMS and program using it. You should choose the most appropriate language to program applications (instead of using SQL).ĭatabases and SQL are useful to store and retrieve data SQL is not a good language to create programs. Nevertheless, the examples are only illustrative. To allow comparisons with other programming languages, the examples are the same adopted in previous languages. The remainder of this text assumes the use of SQLite, though some examples may work with other options. Nevertheless, after you learn one, it is relatively simple to start programming on others.Īfter all, the concepts are the same or similar. Unfortunately, resources and even the syntax to program in SQL can vary among different DBMSs. SQLite is, perhaps, the simplest option for beginners, as it does not require configuring services.ĭatabases created by SQLite are individual files, something that makes the DBMS an excellent choice to be embedded in other programming languages (for instance, in the C programming language or Python).įor servers or complex databases, the other options can be more suitable. The DBMS is the system that managers the database, and is responsible to define how to perform the operations defined in SQL. The first step to start programming with databases is choosing a DBMS. In other words, normally the choice of how the command will be performed is the responsibility of the DBMS instead of the programmer's.Įither as a primary language for database administrators and designers, or as a secondary language for software developers, SQL is a useful programming language.Ĭomplex applications for multiple domains use databases to store and retrieve data required for multiple sessions of use or for different users.ĭatabases deserve own topics for discussion, something that is not on the scope of this page.įor SQL documentation, ideally you will refer to the resources provided by your choice of DBMS. In declarative languages, programmers define what a machine should do, instead of instructing a computer about how it should perform a task. SQL is a programming language following the declarative paradigm. ![]() It can also serve as the primary language for people who are interested in administering or modeling databases (like database administrators or DBAs). In other words, SQL is an excellent secondary programming language. Therefore, it is usually a good option to work with structured data. The reason is that virtually every program has data complex program can have large amounts of data. The language is not suitable for writing programs or applications, though it can be a good introductory option. Structured Query Language (SQL) rarely is the first choice of people who want to learn programming. SQL as the First Programming Language Python and Lua lead my list of recommended programming languages for beginners, as previously commented in introduction about development environments the third option is JavaScript, due to the Internet. Therefore, if certain paragraphs seem familiar, it will not an impression, but déjà vu.Īs a matter of fact, this will also occur in new entries about development environments for other programming languages.Īfter all, the setup procedures are similar. Part of the contents of this page will be identical to the Python's page.
