SaaS: Software as a service (SaaS; pronounced /sæs/) is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted. It is sometimes referred to as “on-demand software”. SaaS is typically accessed by users using a thin client via a web browser. (https://en.wikipedia.org/wiki/Software_as_a_service)
PaaS: Platform as a service (PaaS) is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. (https://en.wikipedia.org/wiki/Platform_as_a_service)
IaaS: Infrastructure as a Service (IaaS) is a form of cloud computing that provides virtualized computing resources over the Internet. IaaS is one of three main categories of cloud computing services, alongside Software as a Service (SaaS) and Platform as a Service (PaaS).

Metrics in Banking Industry: ARPU/COA/COR
ARPU: Average revenue per user (sometimes known as average revenue per unit), usually abbreviated to ARPU, is a measure used primarily by consumer communications and networking companies, defined as the total revenue divided by the number of subscribers. … Most telecommunications carriers operate by the month. (https://en.wikipedia.org/wiki/Average_revenue_per_user)
COA: Cost of Acquisition. A business sales term referring to the expense required to attain a customer or a sale. In setting a marketing and sales strategy, a company must decide what the maximum cost of acquisition will be, which effectively determines the highest amount the company is willing to spend to attain each customer. http://www.investopedia.com/terms/c/costofacquisition.asp)
COR:The cost of revenue is the total cost of manufacturing and delivering a product or service. Cost of revenue information is found in a company’s income statement, and is designed to represent the direct costs associated with the goods and services the company provides. Cost of revenue is different from cost of goods sold (COGS) because it includes costs outside of production, such as distribution and marketing.

SCCM: System Center Configuration Manager. System Center Configuration Manager (SCCM, also known as ConfigMgr),formerly Systems Management Server (SMS) is a systems management software product developed by Microsoft for managing large groups of computers running Windows NT, Windows Embedded, OS X, Linux or UNIX, as well as Windows Phone, Symbian, iOS and Android mobile operating systems. Configuration Manager provides remote control, patch management, software distribution, operating system deployment, network access protection and hardware and software inventory.

PERL: Practical Extraction and Reporting Language. Perl is a family of high-level, general-purpose, interpreted, dynamic programming languages. The languages in this family include Perl 5 and Perl 6. Perl was originally developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier.[9] Since then, it has undergone many changes and revisions. Perl 6, which began as a redesign of Perl 5 in 2000, eventually evolved into a separate language. Both languages continue to be developed independently by different development teams and liberally borrow ideas from one another. (https://en.wikipedia.org/wiki/Perl)
Graph Database: Nodes/Edges/Properties
graph database is a database that uses graph structures for semantic queries with nodes, edges and properties to represent and store data. A key concept of the system is the graph (or edge or relationship), which directly relates data items in the store. The relationships allow data in the store to be linked together directly, and in most cases retrieved with a single operation.
Graph databases are based on graph theory. Graph databases employ nodes, edges and properties.
Nodes represent entities such as people, businesses, accounts, or any other item you might want to keep track of. They are roughly the equivalent of the record, relation or row in a relational database, or the document in a document database.
Edges, also known as graphs or relationships, are the lines that connect nodes to other nodes; they represent the relationship between them. Meaningful patterns emerge when examining the connections and interconnections of nodes, properties, and edges. Edges are the key concept in graph databases, representing an abstraction that is not directly implemented in other systems.
Properties are pertinent information that relate to nodes. For instance, if Wikipedia were one of the nodes, one might have it tied to properties such as website, reference material, or word that starts with the letter w, depending on which aspects of Wikipedia are pertinent to the particular database.
