15 \section{Overview of \emph{\productbasename{}}}
16 %Section tag: pov0
17 \label{ciov0:spov0}
18
19 \emph{\productbasename{}} is a server-based and primarily web-based
20 collaboration product to serve the enterprise that develops software.
21 The \emph{\productbasename{}}
22 software (all of which runs on the server-side) will run only
23 on *nix platforms. The clients that use the software (web browsers)
24 may be run on any platform; including \emph{Windows}, \emph{Linux}, and
25 various embedded platforms such as intelligent cellphones and PDAs.
26
27 The \emph{\productbasename{}} software may be used in two primary ways
28 (not mutually exclusive):
29
30 \begin{itemize}
31 \item The product may be used as-is with no modifications.
32 \item The existing authentication and database framework may be used
33 to speed development of custom database applications; either
34 supplanting or completely replacing existing database
35 functionality.
36 \end{itemize}

42 \section{Challenges in the Software Development Enterprise}
43 %Section tag: CEN0
44 \label{ciov0:scen0}
45
46 Software development is typically characterized by:
47
48 \begin{itemize}
49 \item Awesome complexity and hundreds or thousands of details.
50 \item The need to resolve every detail correctly (this stems
51 directly from the nature of software and the requirement
52 for absolute correctness).
53 \item The need to create or import workproducts and move them through
54 a defined process.
55 \item The need to capture many different forms of data (for example,
56 scanned documents as
57 \emph{.PDF}\index{PDF file@\emph{.PDF} file} files or
58 images of product defects as
59 \emph{.JPG}\index{JPG file@\emph{.JPG} file} files) and integrate
60 them into a defined process.
61 \item The need to integrate individuals who are only peripherally part
62 of the enterprise (for example, customers and suppliers) into the
63 process.
64 \item The need to work and access data securely from remote locations (for example,
65 from home, from coffee shops, from libraries, from cellphones and PDAs,
66 from customer sites, and from foreign countries and airport kiosks
67 while traveling).
68 \end{itemize}
69
70 The complexity and need for correctness conflict directly
71 with human limitations in the following ways:
72
73 \begin{itemize}
74 \item Humans cannot reliably manage large numbers of details without
75 the danger of neglecting some of the details.
76 \item In the presence of large numbers of tasks to be
77 completed, humans often have difficulty identifying
78 the tasks that need to be completed and selecting
79 a task.
80 \item When forced to switch between tasks, humans cannot
81 efficiently save and restore context.
82 Typically, resuming a task
83 involves a brief period of reviewing the status of
84 the task and planning how to proceed.
85 \end{itemize}
86
87 Standard web database and
88 \index{two-factor authentication}two-factor authentication
89 technology can address all of the needs cited above.

95 \section{The \emph{buy-versus-build} Decision}
96 %Section tag: BVB0

99 \index{buy-versus-build}
100
101 Many software development organizations are reluctant to develop collaboration
102 tools in-house, citing the standard arguments against crafting solutions.
103
104 For certain commodity items---such as software development tools, version control
105 systems, and defect tracking systems---the \emph{buy} decision works well.
106
107 However, for non-commodity items, it usually happens that the commercial tools
108 available for purchase don't precisely fit enterprise processes and can't be
109 modified or customized. The enterprise is left with two choices:
110
111 \begin{itemize}
112 \item Purchase commercial tools that don't fit enterprise processes, forcing
113 the enterprise to misuse the tools or modify its processes to fit the
114 processes supported by the tools.
115 \item Fail to purchase commercial tools and forego tool support.
116 \end{itemize}
117
118 If, at every opportunity to make a buy-versus-build decision, the enterprise
119 chooses \emph{buy}, the end result after several years will be persistent gaps
120 in enterprise tool coverage. Most organizations in fact end up with
121 persistent gaps in tool coverage.
122
123 \emph{\productbasename{}-\productversion{}} is essentially a ``catch-all''
124 database framework designed to allow an organization to satisfy all unmet
125 database/collaboration needs in \emph{one} alternate framework.

141 \section{Records Retention Todos}
142 %Section tag: RRT0
143 \label{ciov0:srrt0}
144
145 Need to incorporate the following capability into the tool:
146
147 \begin{itemize}
148 \item \textbf{Legal Hold:}\\
149 Tool must be able to suspend deletion of some or all records
150 to support ``legal hold'' and similar notions. This probably
151 means that in addition to suspending records retention deletions,
152 the database views have to disregard older records as if they have been
153 deleted (i.e. virtual non-existence).
154 \item \textbf{Visible Record of Changes:}\\
155 The tool must not allow changes to be made that are ``silent'' where
156 the new data appears with no clear record that the data has been changed.
157 \emph{Bugzilla}, for example, shows changes via ``bug history''. For all data,
158 there has to be a view of how, when, and by who it was modified.
159 \end{itemize}
