1 Building applications in less time Introduction to the Open Standard Business Platform (OSBP) Eclipsecon France 2018 Ralf Mollik, Compex Systemhaus GmbH, Heidelberg, Germany

2 Our Vision Our values are: team spirit, transparency, independency Devoted to open standard business applications 2

3 Guidelines Open Comprehensible and implementable source code and business processes. (de facto) Standards Standards are to be respected. It is better to use existing standards than to create one s own. Collaborative processes Voluntary and market-driven development and approval following a transparent, consensus-driven process that is reasonably open to all interested parties. 3

4 Become independent & protect investments Future-proof and independent from: programming languages system environments databases Application know-how by means of: domain specific modeling (DSM) domain specific languages (DSL) using best practices etc. operating systems devices 4

5 2BEE Concept BEE - Business Engineering Environment (1) BEE - Software A software factory in form of a integrated development environment, designed for the implementation of business applications and their functionalities conducting and executing described business models. BEE - Best Enterprise Engineering (2) BEE Method A method describing how to implement business models starting with its organizational context converting them into business applications. 5

6 2BEE Concept BEE - Business Engineering Environment (1) BEE - Software utilizes the best frameworks and cultivates relationships with high potential technology partners BEE - Best Enterprise Engineering (2) BEE Method based on V-Modell XT (macro scale), Scrum (micro scale), Prince 2 (organization) 6

16 Typical Software Development Source code is generated based on some written specification. Know-how is stashed in the source code. Specification Source Code Programming 16

17 Concept - Software factory Know-how is molded in an independent model respectively in a DSL. Model DSL Editor 17

18 Concept - Software factory One model (DSL) is mapped to a distinct component environment. Model DSL UI Generator Source Code: Java, etc. Business Rules Configuration files, etc. Data 18

19 Concept - Software factory A component environment is customized to build an application. Model DSL UI Application Source Code e.g. Java Browser Configuration etc. Services DB-Configuration Data 19

20 Models & DSL A model is a: representation of a system using general rules and concepts abstraction of things in the real world whether physical or social (virtual) classes represent abstractions of things A model that describes selected aspects of a sphere of knowledge is called a domain model A process that creates classes is called computer language A computer language specialized to a particular application domain is a domainspecific language (DSL) A model that describes a DSL is called Semantic Model and comes along with a Grammar enforcing its syntactical usage 20

Models & DSL Knowledge about programming Software developers define algorithms Algorithms remain persistent even when personell of the code generator changes Algorithms in the code generator are

21 Models & DSL Knowledge about programming Software developers define algorithms Algorithms remain persistent even when personell of the code generator changes Algorithms in the code generator are non-regressive Algorithms are progressive in terms of performance and security DECOUPLED FROM Professional knowledge Specialists define models Expertise remains persistent even with staff changes in the model Readable as a requirement specification Self-documenting Expandable at any time Combinable Can be commented 21

23 OS.bee paradigm Domain know-how is stored in models which are independent from platforms Coding know-how and patterns are stored in generators Therefore OS.bp and OS.bee applications are future-proof and independent from: frameworks programming languages system environments databases operating systems devices

28 Why OS.bp and OS.bee? Reduces time to market & total cost of ownership: engineered to minimize your costs of software development and deployment Open standards: 100% transparent, can be extended at any time to any requirement Protects investments: through independence of programming languages, operating systems, databases, etc. Best practices: Many years of experience in Softwaredevelopment condensed into proven methods 29

29 Why OS.bp and OS.bee? Solid technology stack: based on proven, best in class technologies with one of the largest open source ecosystems Model driven: efficient reusable development techniques Customizable reference model: design your own business applications using worldwide-approved engineering methods and functionality Flexible, ergonomic and intuitive user interface: automatically created for different devices/working environments 30

30 Live demonstration Business Engineering Environment (BEE )

31 Live Demo By drag and dropping a csv file on the Software factory we will generate a java app (OS.app) that will: generate a database with the data structure of the excel sheet upload the data from the csv file to the database offer a tab and a dialogue view to edit the data uploaded generate BI reporting generate a download functionality to write the database data to a csv file data protection by authorization and authentication mechanism 32

32 App Up in 5 minutes Product Open Data Brand Owner A Brand Owner is the owner of a brand. Brand Type A Brand Type is a group under which brands are classified. Brand A Brand is a symbol, word or a combination of these. 33

33 App Up in 5 minutes Product Open Data GTIN The Global Trade Item Number is a unique international number used to identify products. Package Type The package type represents the package of a GTIN. 34

34 App Up in 5 minutes By drag and dropping several csv files on the OS.bee software factory an application with a complex data model can be automatically generated. 35

35 App Up in 5 minutes csv file has been uploaded 36

36 App Up in 5 minutes Data can be edited in the OS.bee software factory (eclipse) 37

37 App Up in 5 minutes Column attributes can be defined by clicking on the column header. 38

38 App Up in 5 minutes Press button to create java app 39

39 App Up in 5 minutes Result: login for authentication and authorization has been generated 40

40 App Up in 5 minutes Result: upload interface has been generated Press button to import data from the csv file to the java app database 41

41 App Up in 5 minutes Result: download interface has been generated Press button to export data from the java app database to a csv file 42
