1. Reduced Cost and Time-of-Retrieval by developing intelligence
over an existing Electronic Data Discovery tool for
a Litigation Support Services Provider

2. T h e c l i e n t s e r v e s l e a d i n g
corporations, law firms and
government agencies through their
broad range of litigation and business
consulting services. Dealing with
large amount of data, the client
wanted a seamless electronic data
discovery tool that would provide
them digital archival and retrieval of
data so as to ensure security and
reliability for future reference. The
c l i e n t a p p r o a c h e d S i g m a
Infosolutions to leverage their
expertise on Electronic Data
Discovery and develop a robust tool
that could automate large scale data
search and retrieval. This tool will
integrate with the suite of e-
discovery solutions already offered
by the client.
Headquartered in Seattle, the client is a premier provider of broad range of
litigation & business consulting services to corporations, law firms and
government agencies across NorthAmerica.
The ClientExecutive Summary
The client initially used DT Search for retrieving sensitive data from its
customers’ network. However, every time the discovery needed to be
performed, a thin client had to be installed on its customers' network. This
limited flexibility resulted in the client having to manually share and unshare
the drives in the network and also manually copy the information to a specific
location. The client wanted a domain expert to design, build,and test an
electronic data discovery tool that would provide centralized access to all
necessary data needed for zero defect archival & retrieval. They also wanted
the tool to automatically save a copy of the extracted data onto a preferred
location and archive to a common repository when the client plugged back
into its own network. This solution would also improve the overall
performance of the EDD process.

Challenges
The client was often working with sensitive data and could not afford to
compromise on the integrity of the data. This was a significant challenge for
the successful operation of this tool. Also, the tool needed to remove traces
of all activity to ensure security compliance and prevent network
vulnerability. Since the client would plug itself into their customers' network
during this discovery, the tool had to have the capability to crawl across the
network, share the drives, extract data and then unshare drives to ensure
minimal data pilferage risk.
While testing, it was a challenge to simulate up to 1700 boxes and such large
data silos. Preventing network hacks and vulnerability on the network during
extraction was a significant challenge.
Solution
Sigma Infosolution’s team worked closely with the client's team to design and
develop MARCO - comprising of 3 modules namely eDiscovery, Indexing, and
Search Engine. MARCO was implemented as an intelligent solution layer onto
30% time savings
during discovery
and retrieval
of e-documents

3. Technology
 J2EE
 .NET components
 SQL Server 2000 database used for
storage. Compatible with Oracle &
MySQL
 Hibernate used as ORM tool for
efficient connection pooling
 Supports exchange server indexing
(compatible with Exchange Server
2000 & above
Business Benefits
Key benefits included:
 Cost effective tool to review a
large set of data in their native
format
 Faster indexing at a speed of 4-5
GB of data per hour
 Supports Microsoft Exchange
indexing along with files systems
and various document formats
 Supports all the searching features
extended by DT Search
 License Free Software with
complete ownership
 Capability to support context based
search for analysis
the existing DTsearch framework to develop a centralized web-based
application that would offer the combined powerful search capabilities
across an enterprise network. MARCO supported all the basic search types
like boolean, phrase or proximity based, along with fuzzy searching,
relevancy ranking and natural language based searching. MARCO was built to
be installed on an individual laptop of the client's executive and when
connected to an enterprise's network would act as a portable server to
completely automate the document retrieval process. It would:
 Automatically crawl into the network to detect the numerous Microsoft
Windows OS based heterogeneous boxes like e-mail servers, network
servers, backup tapes, desktops, laptops, PDAs, etc.
 Automatically share main drives of these boxes on the network to
perform indexing
 Index all the documents stored in various electronic file formats
 Perform search on the indexed set of documents to acquire the data as
per client's requisites
 Automatically save a local repository of the entire set of documents
searched on to the client's portable server
 Automatically un-share all the various systems attached
 Perform filtering by removing duplicate and other non-responsive files
to retrieve the exact set of e-documents
The entire solution was developed, tested and deployed with zero variance
on schedule and budget.
