Frameworks are large prewritten code to which you add your own code to solve a problem in a specific domain.
You make use of a framework by calling its methods,inheritance,and supplying “call-backs” listeners.
Spring is the most popular application development framework for enterprise Java™.
Millions of developers use Spring to create high performing, easily testable, reusable code without any lock-in.
This file contains the Spring Framework introduction.
Mainly about what is Spring Framework and its components, feature, advantages with a simple program example.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

45. Spring AOP
Spring AOP defaults to using standard J2SE
dynamic proxies for AOP proxies. This enables any
interface (or set of interfaces) to be proxied.
Spring AOP can also use CGLIB proxies. This is
necessary to proxy classes, rather than interfaces
It is good practice to program to interfaces rather
than classes, business classes normally will
implement one or more business interfaces.
SpringByExample.com.ua
45
@ua_spring
46. AspectJ
Spring AOP is often uses the AspectJ declaration
style
AspectJ itself uses Load Time Weaving (LTW) to
modify the bean code according to Aspect logic
LTW could do much more than dynamic proxies but it
is more time-consuming operation. This means that
LTW has a performance drawback.

53. Intro to Hibernate
Object Relational Mapping - is a programming
technique for converting data between incompatible
type systems in object-oriented programming
languages. This creates, in effect, a "virtual object
database" that can be used from within the
programming language.
SpringByExample.com.ua
53
@ua_spring
59. Read-only transactions
A read-only transaction can be used when your
code reads but does not modify data. Read-only
transactions can be a useful optimization in some
cases, such as when you are using Hibernate.
SpringByExample.com.ua

@ua_spring
60. Isolation levels
DEFAULT - The default isolation level for the
underlying resource (usually this is the
READ_COMMITTED isolation level)
SpringByExample.com.ua
60
@ua_spring
61. Isolation levels
READ_UNCOMMITTED - Least restrictive isolation
level. A transaction can read data updates even if
they haven't yet been committed. (The updates
might subsequently be rolled-back).
SpringByExample.com.ua
61
@ua_spring
62. Isolation levels
READ_COMMITTED - A transaction can only read
data that has already been committed. The
transaction doesn't see uncommitted updates.
SpringByExample.com.ua
62
@ua_spring
63. Isolation levels
REPEATABLE_READ - A transaction always reads
the same value after it has read some data. Other
transactions can update the data in parallel with the
original transaction.
SpringByExample.com.ua
63
@ua_spring
64. Isolation levels
SERIALIZABLE - This is the most restrictive
isolation level. Transactions are completely isolated
from each other. Resource managers frequently
implement this isolation level by locking large
amounts of data
