+# Service oriented
+
+Service-oriented architecture (SOA) is an enterprise-wide approach to software development of application components that takes advantage of reusable software components, or services.
+
+SOA provides four different service types:
+
+1. Functional services (i.e., business services), which are critical for business applications.
+2. Enterprise services, which serve to implement functionality.
+3. Application services, which are used to develop and deploy apps.
+4. Infrastructure services, which are instrumental for backend processes like security and authentication.

+# Nosql databases
+
+NoSQL databases (aka "not only SQL") are non-tabular databases and store data differently than relational tables. NoSQL databases come in a variety of types based on their data model. The main types are document, key-value, wide-column, and graph. They provide flexible schemas and scale easily with large amounts of data and high user loads.
+
+Types of NoSQL databases
+* Document databases Ex. MongoDB
+* Key-value databases Ex. Amazon S3
+* Wide-column databases Ex. Cassandra
+* Graph databases Ex. Neo4J
