SQL Compomnents is a compile time tool that build native JDBC Code out of Relationsal database instance. It also provides type safe SQL Builder for safer, secure and productive persdiatnce development. Before we see how it is diffrent from others , We should understand what all we should do when we interact with relational databases from java.
7

Consider a simple Java application that connects to a relational database like PostgreSQL to create a movie store. The database schema looks like this:
10
+
11
+
```sql
12
+
CREATETABLEmovie (
13
+
id smallserial PRIMARY KEY,
14
+
title VARCHAR(80),
15
+
directed_by VARCHAR(80)
16
+
);
17
+
```
18
+
19
+
Now, let's add some movies:
20
+
21
+
```sql
22
+
INSERT INTO movie (title, directed_by) VALUES
23
+
('Inception', 'Christopher Nolan'),
24
+
('The Dark Knight', 'Christopher Nolan'),
25
+
('Interstellar', 'Christopher Nolan'),
26
+
('Dunkirk', 'Christopher Nolan'),
27
+
('Pulp Fiction', 'Quentin Tarantino'),
28
+
('The Matrix', 'Lana Wachowski'),
29
+
('Fight Club', 'David Fincher'),
30
+
('The Social Network', 'David Fincher');
31
+
```
32
+
33
+
Suppose you want to list the movies directed by `Christopher Nolan`. As a Java developer, your responsibilities include:
34
+
35
+
1. Managing database connections
36
+
2. Creating model or DTO classes
37
+
3. Implementing Data Access Objects (DAO)
38
+
39
+
Over the years, various Java frameworks have addressed these challenges in different ways. In the following sections, we’ll explore how these frameworks approach the problem and how SQL Components provides a unique solution.

**Java Persistence API (JPA)** is a well-known framework that abstracts most of the database interaction for Java applications by utilizing **Object-Relational Mapping (ORM)**. JPA handles both **connection management** and **DAO implementation**, leaving the developer to focus on defining **model classes** and mapping them to database tables.

@Entity
13

@Table(name="movie")
14
+
publicclassMovie {
15
+
16
+
@Id
17
+
@GeneratedValue(strategy=GenerationType.IDENTITY)
18

16
31
```java
32
+
publicclassMovieRepository {
33
+
34
+
@PersistenceContext
35
+
privateEntityManager entityManager;
36
+
37
+
publicList<Movie>findByDirector(Stringdirector) {
38
+
String jpql ="SELECT m FROM Movie m WHERE m.directedBy = :director";
SQL Components will do the same functionality with better typesafe API.
46
+
### SQL Components: Flexibility Beyond ORM
47
+
48
+
While JPA simplifies connection management and DAO implementation, **SQL Components** provides greater flexibility by allowing developers to go beyond simple table-to-entity mappings. With SQL Components, you can easily work with **stored procedures**, **views**, and other advanced database features that are often difficult to handle with standard ORM frameworks like JPA.
49
+
50
+
Here’s what sets SQL Components apart:
51
+
52
+
1.**No ORM Restrictions**: SQL Components allows you to fully leverage relational databases without being restricted by table-entity mapping. You can work with **stored procedures**, **views**, and even complex queries effortlessly.
53
+
54
+
2.**Native Java Code Generation**: Unlike JPA, which often relies on **reflection APIs** for dynamic entity handling, SQL Components generates **pure Java code** at compile-time, significantly boosting performance.
55
+
56
+
3.**Type-Safe API**: SQL Components ensures compile-time type checking, reducing runtime errors and offering more reliability.
57
+
58
+
In SQL Components, the same query to list movies directed by a particular director would look like this:
20
59
21
60
```java
61
+
List<Movie> movies =DataManager.getManager().getMovieStore()
62
+
.select(directedBy().eq("Christopher Nolan"))
63
+
.returning();
22
64
```
23
65
24
-
where Model, Data Access Objects Interfaces will be automatically generated.
66
+
**Key Differences**:
67
+
68
+
-**Flexibility**: SQL Components supports stored procedures, views, and advanced SQL features without ORM limitations.
69
+
-**Performance**: Native Java code generation without reflection improves API performance.
