Data Director

BENEFITS

Versatility

Resilience

Remote Administration

Total integration

- The Data Director is

versatile. In addition to being able to

communicate with all versions of

Microsoft Dynamics NAV or AX, it can

also communicate with Microsoft SQL

Server and MicrosoftAccess.

- The Data Director is

resilient to network and server

breakdowns. In case of a network or

server breakdown, packages are

queued up until connections have

b e en r e -e s ta b li s he d a n d t h e

transmission can continue.

- Remote

administration is built into the Data

Director. Abnormal events are loggedinto the Microsoft Windows Event

Log.

- The Data Director

is managed through the familiar

M i c ro s o f t D y n a mi c s N AV / A X

environment. It is fully integrated with

Microsoft Dynamics NAV/AX and LS

Retail.

Data Director in LS Retail NAV

The LS Data Director is a tool which takes care of high-speed data exchange between

different Microsoft Dynamics NAV databases, and other databases that are not based on

Microsoft Dynamics NAV. The Data Director was specifically designed to increase the

speed of replication over Wide Area Networks (WAN). It uses shorter time to send data

and requires lesser bandwidth than previous generations.

These features are especially important to users who have databases in different areas

or regions, as they are able to save communication costs, get higher speed and spend

lesser time.

The Data Director speeds up the replication process by pre-processing the data. Before

the data is sent, it is put into packages that can be re-sent to multiple destinations. This

reduces the time spent in reading data from the source database drastically, since the

data is read only once, even if it is sent to multiple destinations. The packages are

compressed before they are sent, which decreases transmission time even more. The

end result is that the Data Director can be up to 20 times faster than the previous

database replication solutions when performingtypical replication jobs.

Database plugins enablethe DDand theTS to connect to various differentdatabases.

Methods of replication

Normal

Normal with Replication Counter

By Action

- It reads the records from source database, finds the corresponding records indestinationdatabase, and makes them identical

- A normal replication with Replication Counter limitsthe records replicated each time. Replication Counter value is incremented when thereis anyinsertion or modificationin therecords of that table.

- Whenever there is any change (insert, modify, delete or rename) in therecords of a table, system keeps track of those changes. Using By Actions method, thesystem uses Preaction/Actions to replicate data from source table to destination.

Modesof Data Director

Data Director

2nd Stage Data Director

Transaction Server

This is the regular flavour of Data Director. This mode is used to senddata between databases and is non-interactive.

This mode of Data Director is used to forward the datapackages being created by Data Director Service running in Data Director Mode.

This is interactive mode of Data Director used by POS to makequeries into remote databases.

Resilient to network and server breakdowns.

It allowsreplicationof data between twodatabases.

It allowsto schedulethe replication of each table at user defined intervals.

It allowscontrolling data distributioni.e., which records areto be replicated where.

It allows identifies and configures the fields in a table that are to be replicated depending on theirfunctionality.

It offersseveral methods of replication, based on the core area of interest be it the replication timeor the need to extend replicated data from databases to POS terminals, all depending on thetablesbeing replicated.

It allows replication of data between two databases that do not have the same table and fieldstructure.
