Software Engineering 101 Step 1: Brainstorming – Have ideas Step 2: Build it – write code –find the right schema –build test infrastructure Step 3: Run it – make $$$ –deployment: SW + HW configuration –Administration: patches, crashes, … –Management: monitor cost Step 4: Have new ideas – goto Step 2

The devil is in the detail Step 1: Brainstorming – Have ideas Step 2: Build it – write code –find the right schema –build test infrastructure Step 3: Run it – make $$$ –deployment: SW + HW configuration –Administration: patches, crashes, … –Management: monitor cost Step 4: Have new ideas – goto Step 2 All this is fun expensive

The world I dream of... Cost ($$$) –gets automatically cheaper every year –pay as you go along; no investment upfront –cost is predictable (grows linearly with business) Scalability –response time independent of number of clients –predictable client experience, clients never blocked Focus on business –„outsource“ patches, backups, fault tolerance –no need to overspecify application (schema + logic) Level of „ilities“ (consistency, security, availablity,...) –trade for cost

Idea #1 Get rid of the database –no installation, no administration, no upgrade –no investment in servers –no DB software and maintenance cost –no schema upfront: pay-as-you-go-along –no ACID transactions –no three-tier architecture –no DB security (or what we believe what it is)

Idea #2 Make everything a database –declarative programming (XQuery :-) ) applications, distributed protocols, security,... –declarative testing –automatic deployment –automatic optimization –virtualization of hardware –data independence (physical, logical, semantic) –all data survives forever

Challenge Putting it all together –integrate DB + Streams + Virtual Machine –integrate tool chain PL, debugging, deployment, testing, monitoring –simplify architecture: one layer applications –get rid of technology jungle (or hide it) –new business models: make it cheaper for everybody and make a ton of money yourself possible because of hardware trends, micro-payments, and increased volume –train end users to take ownership of their system
