Data Access Layer & Technology

Data access layer and data access technology are generic terms for software that is used to read or write data. Examples include ODBC.

What About SQL?

SQL is not a standalone data access technology but is an integral part of the interactions between the data access technology and databases

SQL (Structured Query Language) is a programming language designed for managing and manipulating relational databases. While SQL itself is not considered a data access technology, it is commonly used in conjunction with data access technologies to interact with databases.

Data access technologies, such as ODBC, JDBC, or ADO.NET provide the mechanisms to connect to databases, execute queries, retrieve data, and perform data manipulation operations. ODBC, JDBC and ADO.NET use some dialect of SQL to communicate with the underlying database system. Other technologies such as Providex use other query languages on the ‘back end’.

In summary, SQL is not a standalone data access technology but is an integral part of the interactions between the data access technology and the database system.
