We specialize in the creation and deployment of business applications using new or existing technologies and services.

We have a team of individuals that understand the broad range of technologies being used in today's environments. Our customers include small businesses using Internet technologies to corporations using very large mainframe systems. Quite often, to reach larger markets or provide a higher level of service to existing customers it requires the newer Internet technologies to work in a complementary manner with existing corporate mainframe systems. We specialize in preparing applications and the associated data that are currently residing on a single platform to be distributed across a variety of platforms.

Preparing the application programs will require the transfer of source members that will be compiled and deployed on the target platform. The data will need to be transferred between the systems and may need to be converted and validated at various stages within the process.

SimoTime has the technology, services and experience to assist in the application and data management tasks involved with doing business in a multi-system environment. Table of Contents.

When technology complements business. We refer file as PS in Mainframe environment. In file data is organized as records. Each record is divided into set of fields. For example data related to employee file which consists of employee ID, employee name, employee Account. In this above file data is organized as multiple records each consists of 33 bytes. Cumulative size of all fields is considered as record length.

A file can be classified as fixed or variable length files. In fixed length file, size of all records must be same but in variable length file record length can be vary upon some fields which are not common.

Files are further classified into 3 types. Sequential files: The records are stored in the file in the same order in which they are entered. Here, the records can be accessed only sequentially. To process any record, one has to read all its preceding records. Further, records cannot be inserted or deleted.

Sequential files are simplest to handle, they are highly inflexible as they do not facilitate insertion and deletion of records. File opened with Extend Mode appends the writing records at the end of the file. An index sequential file is concep- tually made up of two files, a data file and an index file.
