SQL Server Based Software

SQL

 

 

We use SQL Server to store your Business Data. Sql is the safest Data collector with 0% corruption chances. Here is the list of advantages of SQL.

 

Advantages of SQL

 

Reliability

With Access each client reads and writes directly to the raw data tables. If a client machine crashes while writing data this will usually cause the back-end database to also crash and become corrupt. The same thing will occur if the network fails, has a glitch or temporarily becomes overloaded. This problem becomes more apparent as the amount of data or the number of users increases.

With SQL Server the clients do not talk directly with the tables but with an intelligent data manager on the server. This in turn reads and writes data from and to the tables. If a client machine crashes, or the network hiccups, this will not affect the underlying tables; instead the data manager realises that the transaction has not been completed and does not commit the partially transmitted data to the database. The database therefore continues to run without problem.

Performance

With Access all tables involved in a form, report or a query are copied across the network from the server to the client’s machine. The tables are then processed and filtered to generate the required recordset. For example if looking up details for one particular order from an orders table containing, say, 50,000 records then the whole table (all 50,000 records) is dragged over the network and then 49,999 of these records are thrown away (this is an over-simplification since indexing can be used to mitigate this to some extent).

 

The client/server software itself is designed for mission critical systems and is orders of magnitude more reliable than a file server system. On one system that we support the client used to experience around one to two crashes per year (admittedly their network was not exactly state of the art!) when running with an Access database. After we converted it to SQL Server two years ago the system has not experienced a single crash
