An information system is a set of components that collect, store, manipulate, and disseminate data to provide information and feedback. It includes people, hardware, software, networks, and data. Data are raw facts while information is organized data that has additional meaning. Information systems process data into information through tasks like calculating, sorting, and summarizing. They output information to users through displays, paper, or audio and store data in organized files and databases. The value of information depends on how it helps decision makers achieve organizational goals. Information systems support different management levels and functions through transaction processing systems, management information systems, and decision support systems.

Database documentation is an important part of any database project. Good database documentation can help to improve communication and understanding, reduce errors, increase efficiency, improve maintainability, and reduce risk.
There are a number of benefits to having good database documentation, including:
Improved communication and understanding: Good database documentation can help to improve communication and understanding between users, database administrators, and developers. This can lead to better decisions about the design and use of the database.
Reduced errors: Database documentation can help to reduce errors in the database design, implementation, and use. This can save time and money in the long run.
Increased efficiency: Database documentation can help users to use the database more efficiently. This can lead to improved productivity and better decision-making.
Improved maintainability: Database documentation can help database administrators to maintain the database more effectively. This can lead to improved performance and reliability.
Reduced risk: Database documentation can help to reduce the risk of data loss or corruption. This is because database documentation can provide instructions on how to back up and restore the database, and how to recover from data loss or corruption.

Database documentation is a collection of documents that describe a database and its contents. It is important to have good database documentation because it can help users to understand how to use the database, database administrators to maintain the database, and developers to create applications that use the database.
Database documentation can include a variety of different types of documents, such as:
Conceptual models: Conceptual models describe the high-level entities and relationships in the database. They are often used to communicate the design of the database to users and stakeholders.
Logical models: Logical models describe the structure of the database in more detail, including the tables, columns, and relationships between tables.
Physical models: Physical models describe how the database is implemented on the underlying storage system.
Data dictionaries: Data dictionaries provide detailed information about the data in the database, such as the data types, constraints, and default values.
User guides: User guides provide instructions on how to use the database, including how to create, read, update, and delete data.
Administration guides: Administration guides provide instructions on how to maintain the database, such as how to back up and restore the database, and how to grant and revoke access to the database.
Database documentation should be kept up to date as the database is changed. This can be done by using a database documentation tool or by manually updating the documentation whenever the database is changed.
Information Systems is a set of interrelated components that collect (input), manipulate (process), store, and disseminate (output) data and information and provide a feedback mechanism to meet an objective.

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!

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

2. An Introduction to
Information Systems
Information System:
An information system is a set of
interrelated components that collect,
manipulate, store data and disseminate
information and provide a feedback
mechanism to monitor performance.
3. What is an Information
System?
An organized combination of
people, hardware, software,
communications networks, and
data resources that collects data,
transforms it, and disseminates
information.
4. Data Vs. Information
Data: Raw unorganized facts
Information:
A collection of facts organized in such a
way that they have additional value
beyond the value of the facts themselves.
Defining and organizing relationships among
data creates information.
5. Information Concepts
Process:
A set of logically related tasks performed
to achieve a defined outcome.
Knowledge:
An awareness and understanding of a set
of information and ways that information
can be made useful to support a specific
task or reach a decision
6. The Value of Information
The value of Information
is directly linked to how
it helps decision makers
achieve their organization’s
goals.
7. System
A system is a set of elements or
components that interact to
accomplish goals.
13. TPS and ERP
• Transaction
– business related exchange
– Evidence of a business event
• Transaction Processing System (TPS)
– A system which records completed
business transactions
• Enterprise Resource Planning (ERP)
– A set of integrated programs for managing
the entire business operations
14. Business Information
Systems
Management Information System:
A system used to provide routine
information to managers and decision
makers
Decision Support System:
A system used to support problem-
specific decision making
16. Expert System:
A system that gives a computer the ability to
make suggestions and act like an expert in a
particular field.
Knowledge Base:
The collection of data, rules,
procedures, and relationships that
must be followed to achieve value or
the proper outcome.
21. Systems Design,
Implementation, Maintenance
and Review
Determine how the new system will
meet business needs
Put the new system into operation
Ensure the system continues to
meet changing business needs

Interaction with environment (user or other
system) via an interface
29. Input of Data Resources
• Data entry
• Editing
• Machine readable

– Optical scanning; menu; prompts; fill in
blanks
30. Process Data into
Information
• Calculate
• Compare
• Sort
• Classify
• Summarize
The quality of the data must be maintained by a
continual process of correcting and updating
activities
31. Output of Information
• Transmit information to users
– Display; paper; audio
• Storage of data
– Data are retained in an organized manner
• Fields; records; files; data bases
• Control of system performance
– Feedback must be monitored and
evaluated to determine if the information
system is meeting established
performance standards
