Now, let us look a little bit deeper into the peculiarities of schemas as physical objects in different RDBMSs. This logical concept is synonymous with the structure or model of a database. It is important to differentiate between the logical concept of a schema that exists regardless of a specific DBMS and schema as a physical object. Schema Comparison Tableįor better understanding, we have created a comparison table with a set of the main differences between a database and schema: It works as a blueprint that shows where everything is in the database and how it is structured. A schema is basically a formal description of how a database is formed and where everything is located. The data in a database is usually organized in such a way that the information is easily accessible. Taking into account the above-mentioned definitions, let us derive the key differences between the two.Ī database is any collection of data. What is the main difference between database and schema? The schema defines the infrastructure of this field. An easy way to imagine a schema is to think of it as a field that contains tables, stored procedures, views, and related data resources. On the contrary, the term database schema can mean either a visual data representation, a set of rules it is subject to, or a complete set of objects owned by a particular user. Pages of dynamic sites are formed on the fly as a result of the interaction of scripts and databases after a corresponding request from the client to the webserver. Such websites are usually developed using a server-side programming language (for example, PHP) or based on a CMS (for example, WordPress), and do not have ready-made data pages by analogy with HTML sites. Often, these are online stores, portals, and corporate websites. Databases are actively used for dynamic sites with significant amounts of data. What is a database?įirst things first: a database (often referred to as DB) is an organized structure designed to store, modify, and process related information, mostly in large volumes. After that, we will take a closer look at the differences between databases and schemas in the following relational database management systems: SQL Server, MySQL, PostgreSQL, and Oracle.īefore getting into the differences themselves, let us define both terms. To be more precise, we will describe the main differences between these two terms in general. Today, we are going to talk about whether schema and database is the same.
