Data Access Layer is created for accessing the database for the purpose of querying, creating or updating data. The approach can be to create fresh code for a data access layer or use an existing implementation. Some available existing implementations of Data Access Layer are below.

FireStorm DAO

A common design pattern for accessing data is Data Access Object or DAO design pattern. The DAO design pattern makes it easy to separate the object persistence and the logic for data access. The FireStorm API is created on the DAO pattern and is an API tool for accessing the database. The API implementation has been provided by CodeFutures.com, which is a leading provider of database tools for accessibility and performance. The FireStorm API is based on Java and designed to connect with any RDBMS data source like MySQL, Oracle, MS SQL or Sybase. The API is robust however it is designed to be used with Java language only utilizing Java DataBase Connectivity APIs (Codefutures, 2015). The API is chargeable and comes for a license fee.

Google Tag Manager

Google Tag Manager is an open free API that allows to update and manage tags. It offers a data layer for managing and implementing tags. It is simple to use and does not require advance development skills. The API works through a set of specific commands that pull information from the backend. Google Tag Manager is designed to work with web applications. The Javascript-based commands and libraries make the Google Tag Manager independent of platform and implementing programming language (Google.com, 2015).

Spring Data JPA

Spring Data JPA is an API tool for implementing data access layer for applications. The API makes it easy to implement data access layer code by simplifying the querying, updating and pagination of data. The Spring Data API significantly reduces the effort of data layer implementation. The API is config XML based and easy to implement in Java projects. The API implementation is open source and free. The below snippet is a way to include the API library into the project.
<dependencies>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
<version>1.7.2.RELEASE</version>
</dependency>
</dependencies>
