In the computing world, striking a balance between user friendliness and performance is a difficult choice to make. Thus software companies typically end up creating different products aimed at distinct target audiences based on their need for ease of use or complex features. In the RDBMS arena, Microsoft has two distinct offerings, the Ms Access application which is essentially targeted at small businesses and the SQL Server application that is targeted at corporate and large organizations. In Ms Access, Microsoft has included a whole set of features through which it has become exceedingly easy even for a layman to maintain a database and query data from it. The convenience offered by Access has lead many to create Line of Business applications based on it, some of whom often serve as lifelines for many companies. Yet we must all understand that Ms Access has serious limitations and they need to be always kept in mind.
Limit on Concurrent Users
Ms Access does not allow you to have more than 255 concurrent users at any point of time. However when you run a Line of Business application on Access you may find this limit to be rather low in practical terms. In case of a poorly designed application, even 100 users may lead to inconsistent results. Ideally you should restrict the count of users to less than eighty if possible.
The entire database gets saved on one file by default
The Access application by default creates a single MDB file for a given database which not only makes the database vulnerable to corruption but makes operations rather slow when multiple terminals are involved. Ideally you should look to split the database into parts with a separate application containing queries and reports being placed to different terminals.
Small Size Limit
Most versions of Access are restricted at the 2GB limit however in a practical scenario even a 1GB size can give you jitters. You should always regularly compact your database to keep it in shape.
Keeping a Recovery Tool Handy Improves the business reliability of the Ms Access database
As discussed above, Ms Access typically uses a single file to store the entire data unless you decide to split the files. Given the scenario, Ms Access remains quite susceptible to data loss arising out of an MDB corruption issue. Now if you are running a business application on Ms Access and are worried about the security of your data, opting for an access recovery tool would be a prudent choice. Amongst the several applications you may come across, the DataNumen Access Repair application would most likely meet the most stringent demands, given its capacity to negotiate different media types and tackle intricate MDB corruption issues. Further its potency in discovering the location of Access data files along with its capacity to recover data in the quickest possible timeframe would make it a rather agreeable tool for your contingency plans.
