ArangoDB - Using JavaScript in the database
ArangoDB is an open-source NoSQL database that stores data as schema-free JSON documents organized in collections, allowing for flexible data modeling. It provides an HTTP REST API for querying, supports complex SQL-like queries, and enables the creation of server-side JavaScript actions to extend functionality. Additionally, ArangoDB supports referencing between documents and offers special functions for graph processing, making it useful for various application needs.

- 4.Documents and collectionsArangoDB is a database that works withdocumentsDocuments are sets of name / value pairs(think of JSON objects), e.g.{ "name": "Jan", "age": 37 }Documents are organised in collections (liketables in relational databases) www.arangodb.org © j.steemann@triagens.de
- 5.Data types: JSON!ArangoDBoperates on JSON documentsJSON data can be saved as-is:db.users.save({ "name": "Jan", "uses": [ "vi", "js", "C++" ]}); www.arangodb.org © j.steemann@triagens.de
- 6.Schema-freeDocuments can beheterogenous –even in the same collection, e.g.{ "name": "Jan", "age": 37 },{ "name": "Tim", "likes": [ "js" ] },{ "name": { "first": "Patrick", "last": "Star" }}No need to care about schemas www.arangodb.org © j.steemann@triagens.de
- 7.API & protocolsArangoDBserver functionality is exposed via anHTTP REST APIArangoDB answers HTTP queries,so it can be used from the browserSimple to use from Javascript clients(3rd party) drivers available for node.js, Ruby,PHP, ...Javascript-enabled client shell provided www.arangodb.org © j.steemann@triagens.de
- 8.
- 9.Querying is simpleQuerya document by its unique id / key:db._document("users/9558905");Query by providing an example:db.users.byExample({ "name": "Jan", "age": 37}); www.arangodb.org © j.steemann@triagens.de
- 10.IndexesArangoDB allows queryingon any documentattributes or sub-attributesSecondary indexes can be created for higherquery performance:• Hash indexes (equality queries)• Skiplists (range queries)• 2d geo indexes (location queries) www.arangodb.org © j.steemann@triagens.de
- 11.Geo index examples//get b a r n ea r es t t o coor d in a t edb.bars.near(48.51, 2.21).limit(1);// get a ll s h op s w it h in r a d iu s// a r ou n d coor d in a t edb.shops.within(48.51, 2.21, rad); www.arangodb.org © j.steemann@triagens.de
- 12.ReferencesArangoDB can storereferences betweendocumentsReferences are documents with two endpoints(the documents they connect)Reference documents can carry own attributes www.arangodb.org © j.steemann@triagens.de
- 13.References exampleUsers documents: Relations documents: (references){ "name": "Jan", "age": 37 {} "_from": "users/jan", "_to": "users/tim",{ "type": "knows", "name": "Tim", } "city": "Paris"}// q u er y ou t b ou n d r ela t ion s f r om "J a n "db.relations.outEdges(jan); // => tim www.arangodb.org © j.steemann@triagens.de
- 14.Graph queriesReferences makeit possible to process graphswith ArangoDBSome special functions are provided todetermine paths in a graph etc.Can write own Javascript functions for specialtraversals www.arangodb.org © j.steemann@triagens.de
- 15.Query languageArangoDB canalso answer complexSQL-like queriesSuch queries are expressed in ArangoDB'stextual query languageThis language allows joins, sub-queries,aggregation etc. www.arangodb.org © j.steemann@triagens.de
- 16.Example queryFOR uIN users It er a t or FILTER u.addr.country == "US" && (u.isConfirmed == true || u.age >= 18) F ilt er LET userLogins = ( FOR l IN logins FILTER l.userId == u.id RETURN l ) S u b q u er y RETURN { "user": u, "logins": LENGTH(userLogins) } R es u lt www.arangodb.org © j.steemann@triagens.de

- 18.Application serverArangoDB cananswer web requests directlyThis also makes it an application serverUsers can extend its functionality with serverside Javascript „actions“Actions are user-defined functions that containcustom business logic www.arangodb.org © j.steemann@triagens.de
- 19.ActionsActions are boundto URLs and executed whenURLs are called, e.g./users?name=... => function(...)/users/.../friends => function(...) www.arangodb.org © j.steemann@triagens.de
- 20.Actions examplefunction (req,res) { // get r eq u es t ed u s er f r om d b , // n a m e is r ea d f r om U R L p a r a m et er var u = db.users.byExample({ "username": req.urlParameters.name }); // r em ov e p a s s w or d h a s h delete u.hashedPassword; // b ef or e r et u r n in g t o ca ller actions.resultOk(req, res, 200, u);} www.arangodb.org © j.steemann@triagens.de
