-# Final state of exercise 4 for CAA265 - Rapid Service Development with SAP Cloud Application Programming Model
+# Welcome to SAP Cloud Application Programming model samples
 
-**DO NOT MERGE IN MASTER**
+Find here the samples for the openSAP course [Building Applications with the SAP Cloud Application Programming Model](https://open.sap.com/courses/cp7).
+
+## Get Access to SAP Business Application Studio
+The recommended environment for the course is SAP Business Application Studio.  Watch [unit 2 of week 1](https://open.sap.com/courses/cp7/items/51pzQUzbXHr2kdbOmVs6jI) for how to get access.
+
+## Setup
+
+In SAP Business Application Studio, open a terminal.
+Then clone the repo with this specific branch:
+
+```sh
+git clone https://github.com/sap-samples/cloud-cap-samples projects/cloud-cap-samples -b openSAP-week3-unit6
+cd projects/cloud-cap-samples
+```
+
+In the `cloud-cap-samples` folder run:
+```sh
+npm install
+```
+
+## Run
+
+Now you're ready to run the samples, for example:
+```sh
+cd packages/bookshop
+cds watch
+```
+
+After that, watch out for the little popup in the lower right corner of SAP Business Application Studio that asks you to open the application in your browser.
+
+
+## Get Support
+
+Check out the cap docs at https://cap.cloud.sap. <br>

Many writers consider Anna Karenina the greatest work of literature ever,[2] and Tolstoy himself called it his first true novel. It was initially released in serial installments from 1873 to 1877 in the periodical The Russian Messenger.";Leo Tolstoy;4

Scott Fitzgerald that follows a cast of characters living in the fictional towns of West Egg and East Egg on prosperous Long Island in the summer of 1922. The story primarily concerns the young and mysterious millionaire Jay Gatsby and his quixotic passion and obsession with the beautiful former debutante Daisy Buchanan. Considered to be Fitzgerald's magnum opus, The Great Gatsby explores themes of decadence, idealism, resistance to change, social upheaval and excess, creating a portrait of the Roaring Twenties that has been described as a cautionary[a] tale regarding the American Dream.";F.

The novels chronicle the lives of a young wizard, Harry Potter, and his friends Hermione Granger and Ron Weasley, all of whom are students at Hogwarts School of Witchcraft and Wizardry. The main story arc concerns Harry's struggle against Lord Voldemort, a dark wizard who intends to become immortal, overthrow the wizard governing body known as the Ministry of Magic and subjugate all wizards and Muggles (non-magical people).";J.

-201;Wuthering Heights;"Wuthering Heights, Emily Brontë's only novel, was published in 1847 under the pseudonym ""Ellis Bell"". It was written between October 1845 and June 1846. Wuthering Heights and Anne Brontë's Agnes Grey were accepted by publisher Thomas Newby before the success of their sister Charlotte's novel Jane Eyre. After Emily's death, Charlotte edited the manuscript of Wuthering Heights and arranged for the edited version to be published as a posthumous second edition in 1850.";101;12;11.11;GBP;9
-207;Jane Eyre;"Jane Eyre /ɛər/ (originally published as Jane Eyre: An Autobiography) is a novel by English writer Charlotte Brontë, published under the pen name ""Currer Bell"", on 16 October 1847, by Smith, Elder & Co. of London. The first American edition was published the following year by Harper & Brothers of New York. Primarily a bildungsroman, Jane Eyre follows the experiences of its eponymous heroine, including her growth to adulthood and her love for Mr. Rochester, the brooding master of Thornfield Hall. The novel revolutionised prose fiction in that the focus on Jane's moral and spiritual development is told through an intimate, first-person narrative, where actions and events are coloured by a psychological intensity. The book contains elements of social criticism, with a strong sense of Christian morality at its core and is considered by many to be ahead of its time because of Jane's individualistic character and how the novel approaches the topics of class, sexuality, religion and feminism.";107;11;12.34;GBP;10
-251;The Raven;"“The Raven"" is a narrative poem by American writer Edgar Allan Poe. First published in January 1845, the poem is often noted for its musicality, stylized language, and supernatural atmosphere. It tells of a talking raven's mysterious visit to a distraught lover, tracing the man's slow fall into madness. The lover, often identified as being a student, is lamenting the loss of his love, Lenore. Sitting on a bust of Pallas, the raven seems to further distress the protagonist with its constant repetition of the word ""Nevermore"". The poem makes use of folk, mythological, religious, and classical references.";150;333;13.13;USD;1

-271;Catweazle;Catweazle is a British fantasy television series, starring Geoffrey Bayldon in the title role, and created by Richard Carpenter for London Weekend Television. The first series, produced and directed by Quentin Lawrence, was screened in the UK on ITV in 1970. The second series, directed by David Reid and David Lane, was shown in 1971. Each series had thirteen episodes, most but not all written by Carpenter, who also published two books based on the scripts.;170;22;15;EUR;3

Der Roman erzählt in Form einer Ich-Erzählung die Lebensgeschichte von Jane Eyre (ausgesprochen /ˌdʒeɪn ˈɛə/), die nach einer schweren Kindheit eine Stelle als Gouvernante annimmt und sich in ihren Arbeitgeber verliebt, jedoch immer wieder um ihre Freiheit und Selbstbestimmung kämpfen muss. Als klein, dünn, blass, stets schlicht dunkel gekleidet und mit strengem Mittelscheitel beschrieben, gilt die Heldin des Romans Jane Eyre nicht zuletzt aufgrund der Kino- und Fernsehversionen der melodramatischen Romanvorlage als die bekannteste englische Gouvernante der Literaturgeschichte
