Welcome to my series of articles on Unified Modeling Language. This is "Session 5 – Composite Structure Diagram" of the series. Please view my other documents where I have covered each UML diagram with examples
Object modeling represents the static structure of objects and their relationships using object diagrams. An object diagram shows instances of classes, their attributes and values, and relationships between objects through links representing associations, generalizations, or aggregations. Object diagrams are useful for understanding object behavior and relationships in a system, as well as its static view and for forward and reverse engineering.
Static modeling represents the static elements of software such as classes, objects, and interfaces and their relationships. It includes class diagrams and object diagrams. Class diagrams show classes, attributes, and relationships between classes. Object diagrams show instances of classes and their properties. Dynamic modeling represents the behavior and interactions of static elements through interaction diagrams like sequence diagrams and communication diagrams, as well as activity diagrams.
The document discusses various types of UML diagrams including use case diagrams, class diagrams, interaction diagrams (sequence and collaboration diagrams), state diagrams, and activity diagrams. It provides details on when each diagram should be used and includes examples to illustrate how to draw each type of diagram. The key points covered are that UML diagrams allow viewing a software system from different perspectives and varying degrees of abstraction, and each diagram type has a specific purpose to model different aspects of a system.
The Unified Modeling Language (UML) is a general-
purpose, developmental, modeling language in the field
of software engineering, that is intended to provide a
standard way to visualize the design of a system.
The document discusses UML component diagrams. It defines a component as a modular, deployable, and replaceable part of a system that encapsulates implementation and exposes interfaces. It describes how component diagrams show the various components in a system and their dependencies. It outlines the purpose of component diagrams as visualizing components, constructing executables through forward and reverse engineering, and describing component organization and relationships.

There are three main types of building superstructures: load bearing, framed, and composite. Framed structures have thinner walls, allowing more floor space and flexibility in design with no height restrictions, but are more expensive for low-rise buildings. Load bearing structures use thicker walls to support themselves, limiting height but providing economy for 1-2 story buildings with less construction time. Both types are appropriate depending on the soil conditions and number of planned stories.
The document discusses load bearing construction and materials. It begins by explaining that load bearing masonry is one of the oldest construction techniques, using stacked stones or bricks as load-bearing walls. It then discusses limitations like poor earthquake performance. Different materials used for load bearing walls are described like stone, brick, and concrete masonry units. Foundation types, evolution of construction techniques, and retrofitting of existing load bearing structures are also summarized.

This document discusses out of autoclave composite manufacturing and resin transfer molding (RTM) as alternative processes to traditional autoclave curing. RTM involves placing fiber reinforcement in a closed mold and injecting resin under pressure and heat without an autoclave. The resin cures as it flows through the mold. RTM produces high strength, lightweight composite parts with complex shapes. It is commonly used for aircraft, boat, and wind turbine components. The document provides overviews of RTM and out of autoclave processes, companies that use RTM, benefits, applications, and references for further information.
1. Structural systems include architectural structures like buildings that are assemblages of components designed to support loads through interconnected members.
2. Loads on structures can be static like dead loads or dynamic like wind loads, and forces like tension, compression, bending, and shear act on structural members.
3. Common structural forms include trusses, arches, shells, frames, and cable nets which use specific geometries and materials like steel and concrete to transfer loads.
This document provides an overview of foundations for building construction. It discusses the importance of foundations in distributing building loads to the ground. There are two main types of foundations - shallow foundations and deep foundations. Shallow foundations include spread footings, grillage foundations, raft foundations, stepped foundations, and mat/slab foundations. Deep foundations transfer loads deep into the earth and include drilled caissons, driven piles, and precast concrete piles. Foundation design considers factors like soil type, structural requirements, construction requirements, site conditions, and cost. The document also discusses waterproofing, drainage, and underpinning foundations.
The document outlines the key components of a building, including:
- The substructure (foundation and footings), superstructure (framed structures using reinforced concrete or prestressed concrete), walls, doors/windows, and finishing works.
- Building services such as electrical works, plumbing, firefighting systems, air conditioning and ventilation, and lifts.
- Other services like building management systems, security, and public address systems.
basic structural system in architectureshahul130103
This document discusses different structural systems including wall slab, post-lintel, and post slab. It provides details on the basic structural elements of slabs, walls, beams, and columns. For each structural system, it describes the load transfer method, structural members, openings allowed, spans, positioning of stairs, punching, cantilevers, and materials used. Examples of each system are given along with discussions of their strengths, weaknesses, opportunities, and threats. Case studies of specific buildings demonstrating wall slab structures are also included.
Package diagrams allow developers to organize model elements such as use cases, classes, and other packages. A package is a general mechanism for grouping these elements and can be rendered as a tabbed folder. Elements within a package can have public or private visibility. Relationships between packages include dependency and generalization. Dependency relationships indicate that one package depends on another, while generalization shows a parent-child relationship. Packages can be merged to combine their contents. Common architecture styles for organizing packages include decomposition, uses, generalization, and layered. These styles aid in tasks like planning, reuse, and managing complexity.

Use case diagrams define interactions between actors and a system to achieve goals. They show functional requirements as processes and the actors that initiate them. Processes can be broken down into smaller components using <<include>> to show integral parts, or <<extend>> to show optional parts. Well-designed diagrams keep the system boundary clear and use appropriate levels of detail.

This document discusses various component models and technologies, including ACME, Java Beans, COM/DCOM/MTS, CORBA, .NET, and OSGi. It covers topics such as component interfaces, connections, interactions, lifecycles, architectures, and specific models like Java Beans. The Java Bean component model is described in more detail, including its key features around reusable software components, interfaces focusing on methods, properties, events, and implementations as simple Java objects or more complex wrappers.
This document provides explanations of interaction overview diagrams and timing diagrams. It defines interaction overview diagrams as a combination of activity and sequence diagrams that can visualize two aspects of object behavior. Timing diagrams are used to represent timing constraints and state changes over time. There are two notation styles for timing diagrams: state lifelines that show states as lines, and value lifelines that show states as areas. An example diagram of an automatic door is presented to illustrate both notation styles.

UI5con 2024 - Bring Your Own Design SystemPeter Muessig
How do you combine the OpenUI5/SAPUI5 programming model with a design system that makes its controls available as Web Components? Since OpenUI5/SAPUI5 1.120, the framework supports the integration of any Web Components. This makes it possible, for example, to natively embed own Web Components of your design system which are created with Stencil. The integration embeds the Web Components in a way that they can be used naturally in XMLViews, like with standard UI5 controls, and can be bound with data binding. Learn how you can also make use of the Web Components base class in OpenUI5/SAPUI5 to also integrate your Web Components and get inspired by the solution to generate a custom UI5 library providing the Web Components control wrappers for the native ones.
Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

When it is all about ERP solutions, companies typically meet their needs with common ERP solutions like SAP, Oracle, and Microsoft Dynamics. These big players have demonstrated that ERP systems can be either simple or highly comprehensive. This remains true today, but there are new factors to consider, including a promising new contender in the market that’s Odoo. This blog compares Odoo ERP with traditional ERP systems and explains why many companies now see Odoo ERP as the best choice.
What are ERP Systems?
An ERP, or Enterprise Resource Planning, system provides your company with valuable information to help you make better decisions and boost your ROI. You should choose an ERP system based on your company’s specific needs. For instance, if you run a manufacturing or retail business, you will need an ERP system that efficiently manages inventory. A consulting firm, on the other hand, would benefit from an ERP system that enhances daily operations. Similarly, eCommerce stores would select an ERP system tailored to their needs.
Because different businesses have different requirements, ERP system functionalities can vary. Among the various ERP systems available, Odoo ERP is considered one of the best in the ERp market with more than 12 million global users today.
Odoo is an open-source ERP system initially designed for small to medium-sized businesses but now suitable for a wide range of companies. Odoo offers a scalable and configurable point-of-sale management solution and allows you to create customised modules for specific industries. Odoo is gaining more popularity because it is built in a way that allows easy customisation, has a user-friendly interface, and is affordable. Here, you will cover the main differences and get to know why Odoo is gaining attention despite the many other ERP systems available in the market.

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

Composite Structure
Diagram
Composite Structure Diagram is used to explore run time instances collaborating over
communication links. In other words Composite Structure diagram allows the users to peek
inside an object and see what it is composed of. Composite structure diagram provides a high
level abstraction of the system which helps modelers and engineers to better explain the
system to others. Its focus to explore the collaboration between entities and run time grouping
of instances. To be honest composite structure diagram is not much of use, there is no clear
boundary defined for using collaborations in composite structure diagram. Examples what I
have seen so far uses collaboration elements in composite structure diagrams. In my opinion it
is better to choose diagrams like sequence diagrams whose syntax is known by most of the
engineers than to go for different type of diagrams.
Elements of an Composite Structure Diagram
Figure 1: Composite Structure Diagram Elements
3. 3
Part
Part refers to one or two object instances that is owned by the class. Part is represented as a
rectangular box inside the classifier. Syntax for Part notation is as follows. All the three (Part
name, Part Type and multiplicity) are optional but should contain at least one of them.
Referenced Part
Part which are associated with other classifier are represented by dotted rectangle. Role names
of the collaboration are included to indicate which object it is collaborating with.
Port
Ports are the interaction points that are used by classifiers to connect with parts and with the
external environment. Ports that are visible to the environment are represented on the
boundary of the classifier, while that are protected to the environment is shown inside the
boundary. Multiplicity could also be associated with Port. There are two types of ports – Service
Port and Behavior Port
Service Port - Ports can be used to expose the services provided by the classifier to its
environment. Ports are service ports by default. In the below example Library Service is a
service class which provides library related services. Search Port is an explicit window for other
objects to interact with this encapsulated component.
Figure 2: Service & Behavior Port
Behavior Port – Port that helps its environment to access the behavior of the classifier. In
simple words -Calling a method of a member object by the containing object.
Part name: Part Type [multiplicity]

Connector
Communication between notations in a composite structure diagram is represented using
connectors. Syntax of a connector shown below.

Constructing Composite Structure Diagram for our Case Study
In our Order Processing system, a lot seem to be happening in Order object. Let us construct
our composite structure diagram for our Order classifier.
Step 1: Identify the parts present in the classifier
Order class interacts with the following classifiers
1. Account class for getting the details of our clients registered customer
2. Order details class for getting information for a particular order
Step 2: Is there any reference roles involved?
There are two reference role involved in our Order Processing System.
1. Account Class refers Client Database for getting registered customer information
2. Order Class refers the inventory for getting product details
Step 3: Presence of service port and behavior port?
We have behavior ports here since Order class has to use the member of other objects.
Step 4: How are they associated?
While looking at connectors we have to look out for multiplicity, role names and connector
name if available.

Our constructed composite structure diagram of Order class in Order Processing system looks
like the figure shown below.
