The most commonly implemented type of database is a relational database , which consists of data tabled in rows and columns and connected to other tables with complementary information by a system of keywords that includes primary keys and foreign keys.

A relational database consists of tables with rows and columns. In a relational database, each row of a table is known as a tuple or a record.

Each column of the table represents a specific attribute or field. The four CRUD functions can be called by users to perform different types of operations on selected data within the database. This could be accomplished using code or through a graphical user interface.

Let's review each of the four components in-depth to fully appreciate their collective importance of facilitating database interactions. The create function allows users to create a new record in the database. Remember that a record is a row and that columns are termed attributes. A user can create a new row and populate it with data that corresponds to each attribute, but only an administrator might be able to add new attributes to the table itself.

The read function is similar to a search function. It allows users to search and retrieve specific records in the table and read their values.

Users may be able to find desired records using keywords, or by filtering the data based on customized criteria. For example, a database of cars might enable users to type in " Toyota Corolla", or it might provide options to filter search results by make, model and year. The update function is used to modify existing records that exist in the database. To fully change a record, users may have to modify information in multiple fields. For example, a restaurant that stores recipes for menu items in a database might have a table whose attributes are "dish", "cooking time", "cost" and "price".

One day, the chef decides to replace an ingredient in the dish with something different. As a result, the existing record in the database must be changed and all of the attribute values changed to reflect the characteristics of the new dish. Sometimes, singular resources can also be specified through query string paremeters in the URL.

This behavior depends on the individual API endpoint. Reading lists of resources is done by requesting a resource endpoint without specifying an individual resources id. Sometimes resources require query string parameters or else they cannot produce valid lists. This is because a web site must be specified to tell the API which applications should be shown.

Resources are retrieved on an individual basis by providing the id of the resource in the URL of the resource endpoint. Some API endpoints also allow specifying individual resources by providing uniquely identifying query string parameters. The files endpoint provides this behavior because only one file can exist for any given physical path, so it is a uniquely identifying query string parameter. When a PATCH request is performed, the properties of the request body are read, and if the resource has a property with the same name the property of the resource will be set to the new value.

Patch request to update the name of the resource.
