Summary of requirement initial analysis, by Reviewer: (as unambiguously as possible, describe who (List of Actors) is interacting with the system, what the business goal is and how the system might support the actor's ability to acheive their goal)

caIntegrator2 has an EAV (Entity-Attribute-Value)

mechanism

for

capturing

datasets

of

new

data

types.

  This

is

necessary

for

them

to

quickly

capture

new

data

for

new

types

of

data,

which

is

a

very

frequent

occurrence

for

their

users.

  However,

they

would

like

to

represent

the

columns

of

these

new

datasets

as

CDEs

in

the

caDSR

so

that

the

dataset

can

easily

be

interpreted

and

reused.

  They

have

designed

a

model

and

a

process

by

which

they

can

easily

create

these

new

dataset

types

in

their

EAV

model,

link

them

to

CDEs,

and

produce

XMI

that

could

be

used

to

create

an

object-oriented

view

of

the

dataset.

While

this

is

similar

to

dynamic

extensions,

it

does

have

some

unique

qualities.

  These

include

the

fact

that

there

is

an

existing

EAV

model

in

use,

the

necessity

to

rapidly

add

entirely

unique

types

of

data,

and

the

fact

that

the

dataset

itself

is

large

and

(for

the

most

part)

numerical

(unlike

clinical/tissue

data).
