 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;11
 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;16

-# Getting Started
-
-Welcome to your new project.
-
-It contains these folders and files, following our recommended project layout:
-
-| File or Folder   | Purpose                              |
-| ---------------- | ------------------------------------ |
-| `app/`           | will contain compiled front bundles  |
-| `app/front/`     | contains frontend app on react       |
-| `app/deployers/` | contains deployment stuff            |
-| `db/`            | your domain models and data go here  |
-| `srv/`           | your service models and code go here |
-| `test/`          | your services tests                  |
-| `package.json`   | project metadata and configuration   |
-| `mta.yaml`       | deployment config                    |
-| `readme.md`      | this getting started guide           |
-| `server.js`      | initial server set up                |
-
-## Development
-
-- Start cds service on 4004 port in watch mode:
-
-```json
-cds watch
-```
-
-- Open `app/front` folder and run next commands. This will install dependencies and run frontend src files watcher. When you will change src files your bundles in app directory will re-compiled. Now you can enjoy development:
-
-```json
-npm install
-npm run watch
-```
-
-> For better frontend development experience use below command instead of watcher. This will start frontend dev server on 3000 port. Now your bundles will be hot reloaded, this means you do not need reload the page to see changes:
->
-> ```json
-> npm run start
-> ```
-
-## Test
-
-- Change package.json db section
-
-```json
-  "db": {
-    "kind": "sql"
-  }
-```
-
-- Run tests
-
-```json
-npm run test
-```
-
-## Deployment
-
-- Make sure you already have hana trial instance in your cockpit dashboard (SAP Cloud Platform).
-  Or if you are using hana instance - change it in mta.yaml config file from hanatrial to hana
-- Change package.json db section
-
-```json
-  "db": {
-    "kind": "hana"
-  }
-```
-
-- Authenticate to the Cloud Foundry:
-
-```json
-cf login
-```
-
-- Open `app/front` folder and run the following commands. This will create frontend production bundles in app subfolder:
-
-```json
-npm install
-npm run build:prod
-```
-
-- Clean up app/deployers/html5Deployer/resources folder from the previous frontend build
-
-- From root directory run:
-
-```json
-mbt build -t ./
-cf deploy media-store_1.0.0.mtar
-```
-
-- Now your services should be deployed with hanatrial instance and filled with initial data
